The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nevertheless, in response to your demands for smaller sized chains lately for substantial engineering machinery this kind of as office gear, health-related machines and industrial robots, we provide 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 like a high-power model of 15. These substantial precision chains are produced under serious high quality management specially essential for small sizes, taking put on resistance also under consideration.
Variety of chain
Refer to your “Low-speed selection”. Even so, the chain operation velocity may be set considerably substantial depending on the type of lubrication as proven in the table under.
Connecting links and offset backlinks
R connecting links are utilised for smaller pitch chains. On the other hand, since their power is lower than that with the base chain, and since the clip is likely to come off in high speed operation, the usage of connecting back links is not recommended. Use a loop chain with out attaching connecting backlinks.
Offset backlinks are available for chains other than 15 and 15H1, but their use is not really proposed for your identical purpose as stated for that R Connecting back links.
Working velocity and variety of lubrication
15: A large precision mini-pitch bushing chain that is definitely smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain amid 
ANSI typical chains applying curl bushings.
35: A ANSI typical bushing chain ideal for smaller precision machines that require large strength.
