The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response towards the demands for smaller sized chains lately for large technology machinery such as office equipment, medical machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power version of 15. These high precision chains are manufactured under severe quality manage especially essential for modest sizes, taking wear resistance also into account.
Choice of chain
Refer towards 
the “Low-speed selection”. However, the chain operation speed might be set considerably high based upon the sort of lubrication as shown while in the table under.
Connecting hyperlinks and offset back links
R connecting hyperlinks are made use of for little pitch chains. Nonetheless, because their strength is lower than that in the base chain, and since the clip is more likely to come off in higher velocity operation, using connecting backlinks is not really suggested. Use a loop chain with out attaching connecting backlinks.
Offset backlinks can be found for chains apart from 15 and 15H1, but their use is not really advisable for that identical explanation as stated for that R Connecting links.
Working pace and sort of lubrication
15: A higher precision mini-pitch bushing chain which is smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain among ANSI regular chains working with curl bushings.
35: A ANSI normal bushing chain suitable for tiny precision machines that need higher strength.
