The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Having said that, in response towards the demands for smaller sized chains in recent years for higher technology machinery such as workplace equipment, medical machines and industrial robots, we offer 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power edition of 15. 
These higher precision chains are manufactured under serious good quality manage especially demanded for compact sizes, taking dress in resistance also into account.
Collection of chain
Refer to your “Low-speed selection”. However, the chain operation pace is usually set substantially high based upon the type of lubrication as proven within the table under.
Connecting hyperlinks and offset hyperlinks
R connecting links are made use of for little pitch chains. However, considering the fact that their strength is reduce than that of the base chain, and since the clip is more likely to come off in substantial speed operation, the usage of connecting backlinks isn’t advisable. Use a loop chain with out attaching connecting backlinks.
Offset links are available for chains other than 15 and 15H1, but their use is not really proposed for the same explanation as stated for your R Connecting backlinks.
Working pace and style of lubrication
15: A high precision mini-pitch bushing chain that is smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI regular chains working with curl bushings.
35: A ANSI normal bushing chain ideal for little precision machines that need substantial power.
