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 times for higher technologies machinery such as workplace equipment, healthcare machines and industrial robots, we supply 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 below significant top quality management primarily essential for tiny sizes, taking dress in resistance also into consideration.
Choice of chain
Refer on the “Low-speed selection”. Having said that, the chain operation pace might be set considerably higher determined by the sort of lubrication as shown from the table below.
Connecting backlinks and offset links
R connecting backlinks are applied for modest pitch chains. Nonetheless, given that their power is reduced than that of the base chain, and because the clip is more likely to come off in high speed operation, the use of connecting backlinks is just not recommended. Use a loop chain without attaching connecting links.
Offset 
backlinks are available for chains besides 15 and 15H1, but their use isn’t encouraged for that exact same cause as stated for the R Connecting back links.
Working velocity and style of lubrication
15: A substantial precision mini-pitch bushing chain that is certainly smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain among ANSI common chains making use of curl bushings.
35: A ANSI typical bushing chain ideal for smaller precision machines that demand high power.
