The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response to your demands for smaller chains in recent times for higher technologies machinery such as workplace gear, health care machines and industrial robots, we supply 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power version of 15. These high precision chains are manufactured underneath significant quality control especially expected for compact sizes, taking put on resistance also under consideration.
Selection of chain
Refer to the “Low-speed selection”. On the other hand, the chain operation pace might be set significantly large dependant upon the kind of lubrication as shown inside the table under.
Connecting links and offset links
R connecting backlinks are utilised for modest pitch chains. Nonetheless, considering the fact that their strength is lower than that with the base chain, and since the clip is prone to come off in substantial pace operation, the usage of connecting back links is not really 
advised. Use a loop chain with no attaching connecting hyperlinks.
Offset links can be found for chains other than 15 and 15H1, but their use is not advisable for your identical purpose as stated for your R Connecting back links.
Operating pace and sort of lubrication
15: A substantial precision mini-pitch bushing chain that is definitely smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain among ANSI conventional chains applying curl bushings.
35: A ANSI standard bushing chain appropriate for smaller precision machines that require substantial strength.
