The smallest chain complying 
to ANSI is 25 of six.35 mm pitch. Having said that, in response to the demands for smaller sized chains in recent years for large engineering machinery this kind of as workplace equipment, health-related machines and industrial robots, we offer 15 of four.7625 mm (3/16 inch) pitch and also 15H1 being a high-power model of 15. These higher precision chains are manufactured under significant excellent handle in particular expected for modest sizes, taking put on resistance also into consideration.
Selection of chain
Refer on the “Low-speed selection”. Nevertheless, the chain operation pace is often set substantially large depending on the kind of lubrication as shown during the table under.
Connecting backlinks and offset links
R connecting back links are utilised for compact pitch chains. However, due to the fact their power is reduced than that from the base chain, and because the clip is likely to come off in higher velocity operation, the usage of connecting backlinks just isn’t advisable. Use a loop chain without attaching connecting back links.
Offset back links can be found for chains besides 15 and 15H1, but their use is not really advised for that exact same purpose as stated for your R Connecting backlinks.
Working velocity and kind of lubrication
15: A higher precision mini-pitch bushing chain which is smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain among ANSI normal chains working with curl bushings.
35: A ANSI regular bushing chain appropriate for tiny precision machines that need substantial strength.
