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 substantial technological innovation machinery such as office equipment, medical machines and industrial robots, we supply 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 as a high-power model of 15. These substantial precision chains are produced underneath severe high quality handle in particular demanded for small sizes, taking wear resistance also into consideration.
Variety of chain
Refer towards the “Low-speed selection”. Even so, the chain operation velocity is usually set substantially higher according to the kind of lubrication as shown while in the table below.
Connecting links and offset hyperlinks
R connecting back links are used 
for small pitch chains. Nonetheless, given that their power is reduce than that with the base chain, and since the clip is more likely to come off in large speed operation, the usage of connecting back links isn’t advised. Use a loop chain with no attaching connecting back links.
Offset hyperlinks can be found for chains apart from 15 and 15H1, but their use is not advisable for that similar cause as stated for the R Connecting hyperlinks.
Operating speed and style of lubrication
15: A higher precision mini-pitch bushing chain which is smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI standard chains employing curl bushings.
35: A ANSI standard bushing chain ideal for smaller precision machines that call for higher power.
