The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response to your demands for smaller sized chains lately for substantial technology machinery this kind of as workplace products, health care machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and also 15H1 like a high-power version of 15. These high precision chains are produced beneath severe high-quality handle primarily required for compact sizes, taking dress in resistance also into consideration.
Collection of chain
Refer to the “Low-speed selection”. Nevertheless, the chain operation pace can be set significantly high according to the sort of lubrication as shown 
during the table under.
Connecting backlinks and offset links
R connecting back links are employed for small pitch chains. Nevertheless, given that their strength is reduced than that of your base chain, and because the clip is likely to come off in higher pace operation, using connecting backlinks isn’t advised. Use a loop chain without attaching connecting links.
Offset backlinks can be found for chains aside from 15 and 15H1, but their use isn’t recommended for the same reason as stated for that R Connecting backlinks.
Working pace and variety of lubrication
15: A large precision mini-pitch bushing chain that may be smaller than a compact drive chain for general applications, 25
25: Smallest bushing chain between ANSI normal chains using curl bushings.
35: A ANSI common bushing chain suitable for little precision machines that call for higher strength.
