The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nevertheless, in response for the demands for smaller chains in recent years for higher engineering machinery such as office equipment, health care machines and industrial robots, we supply 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as being a high-power model of 15. These higher precision chains are manufactured under extreme quality manage particularly essential for tiny sizes, taking dress in resistance also into consideration.
Variety of chain
Refer on the “Low-speed selection”. Even so, the 
chain operation velocity can be set significantly substantial dependant upon the sort of lubrication as shown in the table under.
Connecting back links and offset hyperlinks
R connecting back links are made use of for small pitch chains. On the other hand, given that their power is reduced than that on the base chain, and because the clip is likely to come off in higher pace operation, using connecting links isn’t advisable. Use a loop chain with no attaching connecting backlinks.
Offset hyperlinks can be found for chains apart from 15 and 15H1, but their use is not encouraged for your identical motive as stated for your R Connecting backlinks.
Working velocity and sort of lubrication
15: A large precision mini-pitch bushing chain that is smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain between ANSI standard chains employing curl bushings.
35: A ANSI standard bushing chain appropriate for small precision machines that need substantial strength.
