The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nonetheless, in response to the demands for smaller sized chains in recent times for high technologies machinery this kind of as office gear, medical machines and industrial robots, we present 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 as a high-power version of 15. These substantial precision chains are manufactured underneath severe good quality manage particularly needed for modest sizes, taking put on resistance also under consideration.
Choice of chain
Refer to your “Low-speed selection”. Having said that, the chain operation velocity can be set considerably higher determined by the sort of lubrication as shown within the table below.
Connecting backlinks and offset back links
R connecting hyperlinks are applied for small pitch chains. Having said that, due to the fact their strength is reduced than that on the base chain, and because the clip is prone to come off in higher speed operation, the usage of connecting back links isn’t suggested. Use a loop chain without having attaching connecting backlinks.
Offset backlinks are available for chains besides 15 and 15H1, but their use isn’t recommended for that identical cause as stated for that R Connecting hyperlinks.
Working velocity and variety of lubrication
15: A higher precision mini-pitch bushing chain that is certainly smaller than a compact drive chain for general applications, 25
25: Smallest bushing chain amid ANSI standard chains using curl bushings.
35: A ANSI common bushing chain suitable for 
modest precision machines that need higher power.
