The rear axle driveshaft sits at the heart of this mechanical chain, channelling thousands of newton-metres of torque through angles and distances that would destroy lesser components within weeks. A properly engineered cardan coupling is not simply a convenience in these machines; it is the structural spine that makes continuous operation economically viable. At Ever Power, we have spent nearly two decades designing, manufacturing, and refining cardan shaft assemblies specifically for the punishment of large-scale mineral extraction environments \u2014 and in this article, we walk through exactly why these components matter, how they work, and what to look for when specifying them for heavy mining truck rear axle applications.<\/p>\n<\/div>\n<p><!-- PRODUCT IMAGE BLOCK 1 --><\/p>\n<div style=\"padding: 2% 4% 3%; background: #f4f6fb; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; justify-content: center; align-items: stretch;\">\n<div style=\"flex: 1 1 280px; max-width: 420px; border-radius: 10px; overflow: hidden; box-shadow: 0 6px 30px rgba(13,27,42,0.13); transition: transform 0.3s, box-shadow 0.3s; border: 2px solid #e2e8f0;\">\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: 240px; object-fit: cover; display: block;\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-cardancoupling.top-4-1-1.webp\" alt=\"Heavy duty cardan coupling for mining truck rear axle driveshaft\" title=\"\"><\/p>\n<div style=\"padding: 14px 16px; background: #fff;\">\n<p style=\"margin: 0; font-size: clamp(12px, 1.2vw, 14px); color: #4a5568; font-weight: 600;\">Ever Power \u2014 Heavy-Duty Cardan Coupling Series for Mining Applications<\/p>\n<\/div>\n<\/div>\n<div style=\"flex: 1 1 280px; max-width: 420px; border-radius: 10px; overflow: hidden; box-shadow: 0 6px 30px rgba(13,27,42,0.13); transition: transform 0.3s, box-shadow 0.3s; border: 2px solid #e2e8f0;\">\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: 240px; object-fit: cover; display: block;\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-cardancoupling.top-5-1-1.webp\" alt=\"Cardan shaft coupling components for ultra-class mining vehicle drivetrain\" title=\"\"><\/p>\n<div style=\"padding: 14px 16px; background: #fff;\">\n<p style=\"margin: 0; font-size: clamp(12px, 1.2vw, 14px); color: #4a5568; font-weight: 600;\">Precision-machined universal joint flanges with high-load cross assemblies<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- ENQUIRY BUTTON --><\/p>\n<div style=\"padding: 2% 4%; background: #fff; text-align: center; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<p><a style=\"display: inline-block; background: linear-gradient(135deg, #e63946, #c1121f); color: #fff; font-size: clamp(14px, 1.8vw, 18px); font-weight: 800; letter-spacing: 1px; padding: 16px 40px; border-radius: 6px; text-decoration: none; box-shadow: 0 4px 24px rgba(230,57,70,0.35); transition: transform 0.2s, box-shadow 0.2s;\" href=\"mailto:sales@cardancoupling.top\">\ud83d\udce7 Request a Custom Quote \u2014 sales@cardancoupling.top<\/a><\/p>\n<p style=\"margin: 10px 0 0; font-size: clamp(11px, 1.2vw, 13px); color: #718096;\">UK &amp; Global Enquiries Welcome \u00b7 Typically respond within 4 business hours<\/p>\n<\/div>\n<p><!-- SECTION: THE CHALLENGE --><\/p>\n<div style=\"padding: 3% 4%; background: #f4f6fb; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px, 3vw + 6px, 32px); font-weight: 800; color: #0d1b2a; margin: 0 0 20px; border-left: 5px solid #e63946; padding-left: 16px;\">The Real Engineering Challenge: Why Mining Truck Rear Axles Break Couplings<\/h2>\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: 180px; object-fit: cover; display: block;\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-39-1-1.webp\" alt=\"Mining truck rear axle driveshaft cardan coupling application\" title=\"\"><\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; width: 100%; max-width: 100%; box-sizing: border-box;\">\n<div style=\"flex: 1 1 260px; background: #fff; border-radius: 10px; padding: 3%; box-shadow: 0 4px 20px rgba(13,27,42,0.09); border-top: 4px solid #2563eb; transition: transform 0.3s, box-shadow 0.3s; box-sizing: border-box;\">\n<div style=\"font-size: 28px; margin-bottom: 8px;\">\u26a1<\/div>\n<h3 style=\"font-size: clamp(15px, 1.8vw, 19px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Shock Torque Spikes<\/h3>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); color: #4a5568; line-height: 1.75; margin: 0;\">When an ultra-class mining truck hits a rock ledge at 15 km\/h with a 220-tonne payload, the drivetrain experiences impulsive torque loads that can reach 3\u20135\u00d7 the nominal operating torque in milliseconds. Standard industrial couplings fracture under this kind of shock without warning, causing costly unscheduled downtime and, more critically, safety incidents. A mining-grade cardan coupling must absorb, dampen, and redistribute these spikes without fatigue cracking.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; background: #fff; border-radius: 10px; padding: 3%; box-shadow: 0 4px 20px rgba(13,27,42,0.09); border-top: 4px solid #e63946; transition: transform 0.3s, box-shadow 0.3s; box-sizing: border-box;\">\n<div style=\"font-size: 28px; margin-bottom: 8px;\">\ud83d\udcc8<\/div>\n<h3 style=\"font-size: clamp(15px, 1.8vw, 19px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Continuous Angular Misalignment<\/h3>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); color: #4a5568; line-height: 1.75; margin: 0;\">Rear axle housings in mining trucks flex, twist, and shift under dynamic loading. The driveshaft between the transfer case output and the axle input must accommodate angular offsets that change constantly as the suspension compresses and rebounds. A rigid shaft would fracture within hours; a cardan coupling with properly matched universal joint geometry handles these angles \u2014 typically up to 15\u00b0 \u2014 continuously and without generating prohibitive vibration harmonics.<\/p>\n<\/div>\n<div style=\"flex: 1 1 260px; background: #fff; border-radius: 10px; padding: 3%; box-shadow: 0 4px 20px rgba(13,27,42,0.09); border-top: 4px solid #16a34a; transition: transform 0.3s, box-shadow 0.3s; box-sizing: border-box;\">\n<div style=\"font-size: 28px; margin-bottom: 8px;\">\ud83c\udf1e<\/div>\n<h3 style=\"font-size: clamp(15px, 1.8vw, 19px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Extreme Operating Environment<\/h3>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); color: #4a5568; line-height: 1.75; margin: 0;\">Open-pit mines in the UK \u2014 from Cornish kaolin operations to Welsh slate quarries and Scottish aggregates sites \u2014 expose drivetrain components to silica dust, standing water, sub-zero overnight temperatures, and abrasive particulate ingress that destroys standard sealing arrangements.

In a mining truck&#8217;s rear axle driveshaft, this typically takes the form of a two-joint or three-joint assembly where the central slip spline accommodates axial length changes as the suspension travels through its range of motion.<\/p>\n<p style=\"font-size: clamp(13px, 1.5vw, 17px); line-height: 1.85; color: #2d3748; margin: 0 0 14px;\">The critical engineering detail that separates a well-designed cardan coupling from a poorly specified one is the phasing of the joints. When both universal joints in a two-joint assembly are set to equal angles and phased correctly \u2014 with their yokes aligned in the same plane \u2014 the inherent velocity variation introduced by the first joint is cancelled by the second. This is known as &#8220;constant-velocity&#8221; phasing and it is non-negotiable in mining truck applications, where uncontrolled velocity fluctuation at the output shaft causes premature bearing wear across the entire rear axle assembly, introduces resonant vibration into the chassis, and accelerates fatigue in the wheel hub bearings.<\/p>\n<p style=\"font-size: clamp(13px, 1.5vw, 17px); line-height: 1.85; color: #2d3748; margin: 0;\">The slip spline section, positioned between the two universal joint assemblies, uses involute spline geometry \u2014 typically 30 teeth or more in heavy mining versions \u2014 to allow axial sliding under load without binding or stick-slip behaviour. Grease retention in this slip section is achieved through a combination of internal grease channels and multi-stage lip seals, maintaining a lubricant film even under the centrifugal forces generated at high rotational speeds.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- APPLICATION SCENE IMAGE STRIP --><\/p>\n<div style=\"padding: 2% 4%; background: #0d1b2a; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<h3 style=\"color: #a8c8e8; font-size: clamp(13px, 1.5vw, 16px); letter-spacing: 3px; text-transform: uppercase; margin: 0 0 16px; font-weight: 600;\">Application in the Field \u2014 Mining Operations<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3633\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-40-1-1.webp\" alt=\"Mining trucks\" width=\"1248\" height=\"832\" title=\"\" srcset=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-40-1-1.webp 1248w, https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-40-1-1-980x653.webp 980w, https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-40-1-1-480x320.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1248px, 100vw\" \/><\/p>\n<\/div>\n<p><!-- SECTION: TECHNICAL SPECS TABLE --><\/p>\n<div style=\"padding: 3% 4%; background: #f4f6fb; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px, 3vw + 6px, 32px); font-weight: 800; color: #0d1b2a; margin: 0 0 20px; border-left: 5px solid #16a34a; padding-left: 16px;\">Technical Specifications \u2014 Mining-Grade Cardan Coupling Reference Parameters<\/h2>\n<p style=\"font-size: clamp(13px, 1.5vw, 17px); line-height: 1.85; color: #2d3748; margin: 0 0 20px; max-width: 900px;\">The parameters below reflect the typical performance envelope of Ever Power&#8217;s heavy-duty cardan coupling series as applied to large mining truck rear axle driveshaft configurations.

In mining trucks that start and stop dozens of times per shift under full payload, this translates directly into measurably longer service life between overhauls.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fff; border: 2px solid #e2e8f0; border-radius: 10px; padding: 3%; box-sizing: border-box; transition: transform 0.3s, box-shadow 0.3s, border-color 0.3s;\">\n<div style=\"font-size: 32px; margin-bottom: 10px;\">\u2696<\/div>\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Dynamic Balancing to G1.0<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 15px); line-height: 1.75; color: #4a5568; margin: 0;\">Our ultra-class cardan coupling assemblies are dynamically balanced to ISO 1940-1 Grade G1.0 on in-house balancing equipment. In practice, this means residual vibration at the rear axle input is reduced to levels measurable only with precision accelerometers \u2014 not felt by the operator or transmitted destructively to wheel hub bearings. For fleets running 20-hour shifts across Welsh quarries or Scottish aggregate sites, balanced shafts mean wheel bearing replacement intervals extend significantly.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fff; border: 2px solid #e2e8f0; border-radius: 10px; padding: 3%; box-sizing: border-box; transition: transform 0.3s, box-shadow 0.3s, border-color 0.3s;\">\n<div style=\"font-size: 32px; margin-bottom: 10px;\">\ud83d\udcc8<\/div>\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Centralised Grease Distribution Channels<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 15px); line-height: 1.75; color: #4a5568; margin: 0;\">Each cross journal assembly is supplied with an internal grease circuit that routes lubricant simultaneously to all four bearing cups through a single grease nipple access point. Under the awkward access conditions typical of a loaded mining truck, this means maintenance personnel can regrease all four contact zones in under two minutes without partial disassembly.

For fleet operators maintaining mixed brands of ultra-class trucks \u2014 a common reality in UK contract mining operations \u2014 this interchangeability reduces spares inventory complexity and accelerates field replacement when a shaft fails at the worst possible moment during peak production.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div style=\"padding: 3% 4%; background: #fff; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px, 3vw + 6px, 32px); font-weight: 800; color: #0d1b2a; margin: 0 0 20px; border-left: 5px solid #2563eb; padding-left: 16px;\">Where Our Cardan Couplings Deliver Results in Mining Truck Rear Axle Systems<\/h2>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; width: 100%; max-width: 100%; box-sizing: border-box;\">\n<div style=\"flex: 1 1 280px; box-sizing: border-box;\">\n<div style=\"background: #f8fafc; border-radius: 10px; padding: 3%; border-left: 4px solid #e63946; margin-bottom: 16px; transition: box-shadow 0.3s;\">\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Ultra-Class Rear Axle Driveshaft (Primary Application)<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 16px); line-height: 1.8; color: #374151; margin: 0;\">The rear axle driveshaft on trucks in the 150\u2013400 tonne payload class connects the transfer box or tandem-drive third differential to the rear drive axle input pinion. In these applications, nominal shaft torques routinely exceed 80,000 Nm at low-speed ramp climbs, with shock multiples during abrupt braking on downhill loaded runs. Our cardan coupling assemblies in this position are designed with forged 42CrMo4 yokes, triple-lip FKM seals, and full dynamic balance to G1.0 to survive the full tyre-to-axle torque chain without inducing resonance into the chassis structure at any loaded speed between 0 and 55 km\/h.<\/p>\n<\/div>\n<div style=\"background: #f8fafc; border-radius: 10px; padding: 3%; border-left: 4px solid #2563eb; transition: box-shadow 0.3s;\">\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Front Axle Steer-Drive Applications<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 16px); line-height: 1.8; color: #374151; margin: 0;\">Some ultra-class mining trucks operate with all-wheel-drive capability for enhanced traction on wet or unstable pit floor conditions \u2014 a genuine issue on UK quarry sites during winter operations. The front steer-drive application demands a cardan coupling that accommodates both the suspension travel angle and the steering articulation simultaneously. Our constant-velocity cardan shaft configurations, using wide-angle joints with phased yoke geometry, provide the precise output velocity uniformity required to prevent tyre wear from non-constant-velocity torque delivery at the front wheels.<\/p>\n<\/div>\n<\/div>\n<div style=\"flex: 1 1 280px; box-sizing: border-box;\">\n<div style=\"background: #f8fafc; border-radius: 10px; padding: 3%; border-left: 4px solid #16a34a; margin-bottom: 16px; transition: box-shadow 0.3s;\">\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Tandem-Axle Intermediate Driveshaft<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 16px); line-height: 1.8; color: #374151; margin: 0;\">On large articulated haul trucks with tandem rear axle configurations, a shorter intermediate cardan coupling assembly connects the primary rear axle differential to the secondary bogie axle. This shaft operates in the most challenging position geometrically \u2014 often at higher working angles due to the bogie pivot articulation \u2014 and requires a wide-angle joint design with a shorter overall length to fit the installation envelope. Our compact mining series addresses this with offset yoke geometry and reduced-diameter journal assemblies that maintain full torque rating within the tighter angular constraints of the tandem layout.<\/p>\n<\/div>\n<div style=\"background: #f8fafc; border-radius: 10px; padding: 3%; border-left: 4px solid #9333ea; transition: box-shadow 0.3s;\">\n<h3 style=\"font-size: clamp(14px, 1.8vw, 18px); font-weight: bold; color: #0d1b2a; margin: 0 0 10px;\">Transfer Case to Main Driveline<\/h3>\n<p style=\"font-size: clamp(12px, 1.3vw, 16px); line-height: 1.8; color: #374151; margin: 0;\">Between the engine-gearbox assembly and the transfer case output, many mining truck configurations use a short cardan coupling assembly to accommodate powertrain flex-mount movement under load and thermal expansion. At this position the torque levels are at their highest absolute values \u2014 the full engine output torque multiplied by the lowest gear ratio \u2014 and the coupling must resist fatigue under millions of torque reversal cycles across the vehicle&#8217;s life. Our high-cycle fatigue testing protocols specifically validate coupling cross and tube assemblies for this position, with test protocols reaching 10 million cycles at 130% nominal torque before sign-off for series production.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3287\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-2-1-1.webp\" alt=\"cardan coupling\" width=\"1248\" height=\"832\" title=\"\" srcset=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-2-1-1.webp 1248w, https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-2-1-1-980x653.webp 980w, https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-2-1-1-480x320.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1248px, 100vw\" \/><!-- SECTION: MATERIALS --><\/p>\n<div style=\"padding: 3% 4%; background: linear-gradient(135deg, #0d1b2a 0%, #1b3a5c 100%); color: #fff; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px, 3vw + 6px, 32px); font-weight: 800; color: #fff; margin: 0 0 20px; border-left: 5px solid #e63946; padding-left: 16px;\">Materials That Define Performance \u2014 Inside the Ever Power Mining Cardan Coupling<\/h2>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; width: 100%; max-width: 100%; box-sizing: border-box;\">\n<div style=\"flex: 1 1 200px; background: rgba(255,255,255,0.07); border: 1px solid rgba(255,255,255,0.13); border-radius: 10px; padding: 3%; box-sizing: border-box; transition: background 0.3s, transform 0.3s;\">\n<p style=\"font-size: clamp(12px, 1.3vw, 14px); text-transform: uppercase; letter-spacing: 2px; color: #e63946; margin: 0 0 8px; font-weight: bold;\">Cross Journals<\/p>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); color: #fff; font-weight: bold; margin: 0 0 8px;\">42CrMo4 Alloy Steel<\/p>\n<p style=\"font-size: clamp(11px, 1.2vw, 14px); color: #a8c8e8; line-height: 1.7; margin: 0;\">Vacuum-arc refined, through-hardened to 58\u201362 HRC on journal surfaces, with 12\u201314 mm case depth on heavy mining variants.

Their existing <a href=\"https:\/\/cardancoupling.top\/hi\/product\/swp-f-long-big-flex-type-universal-joint-coupling\/\">cardan coupling<\/a> supplier \u2014 a European catalogue brand \u2014 was delivering rear axle driveshaft assemblies with an average in-service life of approximately 1,100 hours before significant cross-journal wear necessitated replacement. With six trucks each requiring two to three shaft replacements per year, the combined parts and downtime cost was exceeding \u00a385,000 annually.<\/p>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); line-height: 1.85; color: #374151; margin: 0 0 12px;\">The quarry&#8217;s plant manager contacted Ever Power after seeing our mining-grade cardan coupling specifications referenced in a UK Plant Engineer Association industry bulletin. Following an engineering data exchange \u2014 covering the haul road gradient, loaded vehicle mass, transfer case output flange dimensions, and suspension travel range \u2014 Ever Power proposed a custom heavy mining series assembly using nitrided 42CrMo4 cross journals, quad-lip FKM seals, and a wider slip spline bore to accommodate the higher axial travel at the specific suspension compression angles recorded on the site&#8217;s downhill haul section.<\/p>\n<p style=\"font-size: clamp(13px, 1.4vw, 16px); line-height: 1.85; color: #374151; margin: 0;\">After 18 months of in-service operation across the six-truck fleet, average in-service life before the first cross-journal regreasing intervention reached 2,400 hours \u2014 more than double the previous supplier&#8217;s figures. The first full shaft replacement interval extended to beyond 3,100 hours on four of the six trucks. Total annual drivetrain maintenance cost for the rear axle driveshaft assemblies dropped by approximately 52%, and unscheduled shaft-related breakdowns across the fleet fell from an average of 11 incidents per year to two.<\/p>\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: 180px; object-fit: cover; display: block;\" src=\"https:\/\/cardancoupling.top\/wp-content\/uploads\/2026\/05\/ep-gear-coupling.top-42-1-1.webp\" alt=\"Heavy mining haul truck drivetrain in open pit quarry UK\" title=\"\"><\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- TESTIMONIALS --><\/p>\n<h3 style=\"font-size: clamp(16px, 2vw + 6px, 24px); font-weight: 800; color: #0d1b2a; margin: 0 0 16px;\">What Our Customers Say<\/h3>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; width: 100%; max-width: 100%; box-sizing: border-box;\">\n<div style=\"flex: 1 1 240px; background: #fff; border-radius: 10px; padding: 3%; box-shadow: 0 4px 20px rgba(13,27,42,0.09); border-top: 4px solid #e63946; box-sizing: border-box; transition: transform 0.3s, box-shadow 0.3s;\">\n<p style=\"font-size: 28px; margin: 0 0 8px; color: #e63946;\">\u275d<\/p>\n<p style=\"font-size: clamp(12px, 1.3vw, 15px); line-height: 1.8; color: #374151; margin: 0 0 14px; font-style: italic;\">We&#8217;ve run four of Ever Power&#8217;s ultra-class cardan coupling assemblies on our 180-tonne Komatsu fleet operating out of a Scottish aggregates site for 14 months now.
