The smallest chain complying to ANSI is 25 of six.35 mm pitch. Even so, in response for the demands for smaller chains lately for higher technology machinery this kind of as office gear, medical machines and industrial robots, we provide 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as 
being a high-power edition of 15. These large precision chains are manufactured beneath serious excellent control particularly required for small sizes, taking dress in resistance also into account.
Selection of chain
Refer on the “Low-speed selection”. Nevertheless, the chain operation pace might be set significantly substantial depending on the type of lubrication as proven while in the table under.
Connecting links and offset back links
R connecting hyperlinks are applied for tiny pitch chains. Nonetheless, considering the fact that their power is decrease than that in the base chain, and since the clip is likely to come off in higher pace operation, the use of connecting back links is not encouraged. Use a loop chain with out attaching connecting back links.
Offset links are available for chains apart from 15 and 15H1, but their use isn’t encouraged for the similar cause as stated for your R Connecting links.
Working pace and kind of lubrication
15: A large precision mini-pitch bushing chain that is definitely smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain among ANSI conventional chains making use of curl bushings.
35: A ANSI typical bushing chain suitable for tiny precision machines that call for higher strength.
