The smallest chain complying to ANSI is 25 of six.35 mm pitch. Even so, in response to your demands for smaller sized chains in recent years for substantial technological innovation machinery such as office equipment, health-related machines and industrial robots, we deliver 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as a high-power edition of 15. These large precision chains are manufactured under significant high-quality manage specifically needed for compact sizes, taking dress in resistance also under consideration.
Collection of chain
Refer to your “Low-speed selection”. Even so, the chain operation pace is often set considerably large dependant upon the sort of lubrication 
as proven from the table beneath.
Connecting links and offset backlinks
R connecting hyperlinks are utilized for compact pitch chains. Even so, since their power is reduced than that of your base chain, and since the clip is more likely to come off in substantial pace operation, the usage of connecting links isn’t advised. Use a loop chain without attaching connecting hyperlinks.
Offset links are available for chains besides 15 and 15H1, but their use is not encouraged for that very same reason as stated for that R Connecting hyperlinks.
Operating speed and sort of lubrication
15: A higher precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain amongst ANSI regular chains employing curl bushings.
35: A ANSI conventional bushing chain appropriate for little precision machines that need high strength.
