The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response for the demands for smaller sized chains lately for large technological innovation machinery this kind of as workplace tools, healthcare machines and industrial robots, 
we provide 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as being a high-power edition of 15. These high precision chains are produced below serious high-quality handle specially necessary for compact sizes, taking dress in resistance also into account.
Collection of chain
Refer to the “Low-speed selection”. Nevertheless, the chain operation speed could be set significantly large depending on the type of lubrication as shown while in the table beneath.
Connecting links and offset hyperlinks
R connecting backlinks are used for tiny pitch chains. Nevertheless, since their power is decrease than that of your base chain, and because the clip is more likely to come off in large pace operation, using connecting hyperlinks is just not advisable. Use a loop chain devoid of attaching connecting back links.
Offset back links can be found for chains apart from 15 and 15H1, but their use is just not advised for the very same explanation as stated for the R Connecting backlinks.
Working speed and kind of lubrication
15: A large precision mini-pitch bushing chain that may be smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain between ANSI normal chains making use of curl bushings.
35: A ANSI conventional bushing chain appropriate for compact precision machines that demand large strength.
