The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response on the demands for smaller sized chains lately for large technologies machinery such as office gear, health-related machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 being a high-power version of 15. These high precision chains are manufactured below extreme top quality management especially demanded for smaller sizes, taking wear resistance also into consideration.
Variety of chain
Refer towards the “Low-speed selection”. Nonetheless, the chain operation pace might be set considerably large depending on the type of lubrication as proven from the table under.
Connecting hyperlinks and offset back links
R connecting hyperlinks are made use of for little pitch chains. On the other hand, because their strength is reduce than that with the base chain, and since the clip is more likely to come off in large velocity operation, using connecting back links is not really suggested. Use a loop chain with no attaching connecting back links.
Offset back links can be found for chains apart from 15 and 15H1, but their use isn’t proposed for that identical explanation as stated for the R Connecting links.
Working pace and form of lubrication
15: A large precision mini-pitch bushing chain which is 
smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain amongst ANSI common chains applying curl bushings.
35: A ANSI normal bushing chain appropriate for smaller precision machines that demand large strength.
