Characteristics and Performance Details
The S-Flex coupling style and design is comprised of 3 components: two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth
Torque is transmited by way of the flanges mounted on both the driver and driven shafts via the sleeve
Misalignment and torsional shock loads are absorbed by shear deflection inside the sleeve
The shear characteristic in the S-Flex coupling is very nicely suited to soak up affect loads
The S-Flex coupling provides combinations of flanges and sleeves which may be assembled to fit your particular application
Thirteen sizes can be found with torque capabilities that vary from 60 in-lbs to 72,480 in-lbs
The S-Flex flanges are offered in 5 models which are made from zinc or cast iron
Sleeves are available in EPDM rubber, Neoprene to address a wide range of application specifications
Safety from misalignment, shock, and vibration:
PARALLEL:
The S-Flex coupling accepts as much as .062 in of parallel misalignment with no dress in. The flexible coupling sleeve minimizes the radial loads imposed on gear bearings, an issue frequently connected with parallel misalignment.
AXIAL:
The S-Flex couplings may be used in applications which demand a constrained quantity of shaft end-float without having transferring thrust loads to products bearings. Axial motion of about 1/8 inch accepted.
ANGULAR:
The flexing action in the elastomeric sleeve and also the locking function from the mating teeth permits the S-Flex coupling to effectively handle angular misalignment up to 1??.
TORSIONAL:
S-Flex couplings properly dampen torsional shock and vibration to protect connected gear. The EPDM and Neoprene sleeves have torsional wind-up flexibility of 15?? at their rated torque. Hytrel offers 7??wind-up.
