The smallest chain complying 
to ANSI is 25 of six.35 mm pitch. Having said that, in response to your demands for smaller sized chains lately for higher engineering machinery this kind of as office tools, health-related machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power version of 15. These large precision chains are manufactured under significant excellent control in particular expected for small sizes, taking wear resistance also under consideration.
Variety of chain
Refer for the “Low-speed selection”. Nonetheless, the chain operation velocity can be set significantly substantial based on the sort of lubrication as shown from the table below.
Connecting backlinks and offset back links
R connecting back links are used for compact pitch chains. Nevertheless, considering the fact that their strength is reduce than that from the base chain, and since the clip is more likely to come off in high speed operation, the use of connecting hyperlinks is not really encouraged. Use a loop chain with out attaching connecting hyperlinks.
Offset back links are available for chains apart from 15 and 15H1, but their use is just not advised for the similar motive as stated for that R Connecting links.
Working velocity and type of lubrication
15: A higher precision mini-pitch bushing chain that may be smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain between ANSI conventional chains working with curl bushings.
35: A ANSI regular bushing chain ideal for tiny precision machines that need high power.
