The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Even so, in response to your demands for smaller chains in recent times for high technologies machinery such as office products, health-related machines and industrial robots, we give 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 like a high-power version of 15. These large precision chains are manufactured under severe high quality manage specially required for small sizes, taking wear resistance also into consideration.
Choice of chain
Refer to your “Low-speed selection”. Nevertheless, the chain operation pace is usually set considerably high depending on the kind of lubrication as proven from the table under.
Connecting back links and offset backlinks
R connecting hyperlinks are utilised for small pitch chains. Nonetheless, given that their power is decrease than that with the base chain, and because the clip is likely to come off in higher speed operation, using connecting backlinks will not be recommended. Use a loop chain with no attaching connecting backlinks.
Offset back links are available for chains aside from 15 and 15H1, but their use is not really advisable for your similar purpose as stated for your R Connecting back links.
Operating velocity and form of lubrication
15: A large precision mini-pitch bushing chain that is smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain amid ANSI standard chains applying curl bushings.
35: A ANSI normal bushing chain ideal for little precision machines that require high strength.
