The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response on the demands for smaller sized chains in recent years for higher engineering machinery this kind of as workplace gear, health care machines and industrial robots, we supply 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 like a high-power model of 15. These large precision chains are produced under extreme high-quality management particularly required for modest sizes, taking dress in resistance also into consideration.
Choice of 
chain
Refer towards the “Low-speed selection”. Nonetheless, the chain operation velocity can be set significantly high according to the sort of lubrication as proven inside the table beneath.
Connecting links and offset hyperlinks
R connecting hyperlinks are utilised for tiny pitch chains. However, because their strength is lower than that from the base chain, and because the clip is more likely to come off in high pace operation, using connecting back links is not suggested. Use a loop chain with out attaching connecting links.
Offset backlinks can be found for chains aside from 15 and 15H1, but their use just isn’t recommended for the identical reason as stated for the R Connecting hyperlinks.
Operating speed and kind of lubrication
15: A substantial precision mini-pitch bushing chain that is definitely smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI regular chains employing curl bushings.
35: A ANSI regular bushing chain ideal for small precision machines that demand high strength.
