The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Even so, in response to the demands for smaller sized chains in recent years for higher technologies machinery this kind of as workplace tools, health care machines and industrial robots, we provide 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power model of 15. These substantial precision chains are produced underneath serious top quality handle particularly necessary for tiny sizes, taking dress in resistance also under consideration.
Variety of chain
Refer on the “Low-speed selection”. Nevertheless, the 
chain operation pace may be set considerably large determined by the type of lubrication as proven from the table below.
Connecting back links and offset backlinks
R connecting back links are employed for tiny pitch chains. Having said that, since their strength is decrease than that from the base chain, and because the clip is likely to come off in large speed operation, the usage of connecting back links will not be recommended. Use a loop chain devoid of attaching connecting links.
Offset back links are available for chains other than 15 and 15H1, but their use is not advised to the similar reason as stated for the R Connecting hyperlinks.
Working velocity and kind of lubrication
15: A higher precision mini-pitch bushing chain that may be smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI normal chains applying curl bushings.
35: A ANSI conventional bushing chain ideal for compact precision machines that call for large power.
