The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response to 
the demands for smaller chains in recent times for large technology machinery such as office tools, healthcare machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power version of 15. These higher precision chains are manufactured underneath significant excellent handle primarily essential for tiny sizes, taking put on resistance also into account.
Collection of chain
Refer towards the “Low-speed selection”. On the other hand, the chain operation velocity is often set significantly high determined by the type of lubrication as proven during the table under.
Connecting links and offset back links
R connecting backlinks are made use of for little pitch chains. Having said that, due to the fact their power is reduce than that of your base chain, and since the clip is prone to come off in substantial pace operation, using connecting hyperlinks is just not recommended. Use a loop chain without the need of attaching connecting back links.
Offset backlinks are available for chains besides 15 and 15H1, but their use just isn’t proposed for your identical purpose as stated to the R Connecting backlinks.
Working speed and sort 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 amongst ANSI conventional chains utilizing curl bushings.
35: A ANSI common bushing chain appropriate for little precision machines that call for high strength.
