The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response on the demands for smaller chains in recent times for large technological innovation machinery such as workplace gear, health-related machines and industrial robots, we provide 15 of four.7625 mm (3/16 inch) pitch as well as 15H1 like a high-power version of 15. These large precision chains are produced underneath extreme high quality manage specifically necessary for tiny sizes, taking dress in resistance also into account.
Selection of chain
Refer on the “Low-speed selection”. However, the chain operation speed may be set significantly higher based on the sort of lubrication as shown during the table beneath.
Connecting hyperlinks and offset hyperlinks
R connecting backlinks are utilized for tiny pitch chains. Even so, considering that their strength is reduce than that of your base chain, and because the clip is prone to come off 
in large velocity operation, the usage of connecting back links just isn’t proposed. Use a loop chain with out attaching connecting backlinks.
Offset links are available for chains apart from 15 and 15H1, but their use will not be advised for that identical explanation as stated for that R Connecting backlinks.
Working speed and form of lubrication
15: A large precision mini-pitch bushing chain that is definitely smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain amongst ANSI typical chains applying curl bushings.
35: A ANSI normal bushing chain appropriate for compact precision machines that require substantial power.
