The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response to your demands for smaller chains lately for higher technological innovation machinery such as workplace gear, health-related machines and industrial robots, we supply 15 of four.7625 mm (3/16 inch) pitch as well as 15H1 being a high-power edition of 15. These large precision chains are produced underneath severe top quality handle in particular expected for compact sizes, taking put on resistance also into account.
Variety of chain
Refer to your “Low-speed selection”. Even so, the chain operation velocity can be set considerably high dependant upon the kind of lubrication as proven inside the table beneath.
Connecting hyperlinks and offset hyperlinks
R connecting backlinks are made use of for tiny pitch chains. 
Nonetheless, due to the fact their power is reduced than that in the base chain, and because the clip is prone to come off in high velocity operation, the usage of connecting hyperlinks will not be advisable. Use a loop chain without having attaching connecting backlinks.
Offset back links can be found for chains aside from 15 and 15H1, but their use just isn’t advised for that same purpose as stated for that R Connecting links.
Working speed and form of lubrication
15: A substantial precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain between ANSI typical chains utilizing curl bushings.
35: A ANSI conventional bushing chain suitable for little precision machines that require higher power.
