The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Even so, in response on the demands for smaller sized chains in recent years for substantial technologies machinery this kind of as office tools, health care machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as being a high-power edition of 15. These higher precision chains are manufactured under severe quality handle primarily demanded for little sizes, taking put on resistance also into consideration.
Choice of chain
Refer on the “Low-speed selection”. However, the chain operation velocity might be set considerably higher determined by the type of lubrication as shown while in the table under.
Connecting links and offset hyperlinks
R connecting links are made use of for tiny pitch chains. Having said that, considering the fact that their strength is lower than that in the base chain, and since the clip is likely to come off in large speed operation, the usage of connecting hyperlinks is just not advisable. Use a loop chain without attaching connecting hyperlinks.
Offset back links can be found for chains aside from 15 and 15H1, but their use is not really suggested to the similar explanation as stated for that R Connecting hyperlinks.
Operating velocity and variety of lubrication
15: A higher precision mini-pitch bushing chain that may be smaller sized than a compact drive chain 
for general applications, 25
25: Smallest bushing chain between ANSI common chains working with curl bushings.
35: A ANSI typical bushing chain ideal for smaller precision machines that require higher strength.
