The smallest chain complying to ANSI is 25 of six.35 mm pitch. Having said that, in response to your demands for smaller chains in recent years for higher technology machinery this kind of as workplace products, healthcare machines and industrial robots, we provide 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 as a high-power version of 15. These higher precision chains are produced under serious quality management specifically expected for smaller sizes, taking wear resistance also under consideration.
Choice of chain
Refer to the “Low-speed selection”. However, the chain operation pace can be set considerably high dependant upon the kind of lubrication as proven inside the table under.
Connecting backlinks and offset backlinks
R connecting back links are used for tiny pitch chains. Having said that, considering that 
their power is lower than that of the base chain, and because the clip is more likely to come off in higher velocity operation, using connecting links will not be advised. Use a loop chain with no attaching connecting backlinks.
Offset backlinks can be found for chains other than 15 and 15H1, but their use isn’t advised for that exact same purpose as stated to the R Connecting backlinks.
Working pace and variety of lubrication
15: A high precision mini-pitch bushing chain that is smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain amongst ANSI conventional chains making use of curl bushings.
35: A ANSI common bushing chain ideal for smaller precision machines that need large strength.
