The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nevertheless, in response to the demands for smaller chains in recent years for large technology machinery such as office equipment, healthcare machines and industrial robots, we provide 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 beneath serious high quality manage specially needed for little sizes, taking wear resistance also into account.
Collection of chain
Refer on the “Low-speed selection”. However, the chain operation pace is usually set significantly substantial according to the kind of lubrication as shown within the table below.
Connecting backlinks and offset hyperlinks
R connecting back links are utilised for smaller pitch chains. Having said that, considering the fact that their strength is reduce than that in the base chain, and because the clip is more likely to come off in high pace operation, the use of connecting backlinks is not really advisable. Use a loop chain devoid of attaching connecting links.
Offset hyperlinks are available for 
chains aside from 15 and 15H1, but their use is just not advisable to the very same purpose as stated for the R Connecting hyperlinks.
Working pace and kind of lubrication
15: A higher precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for common applications, 25
25: Smallest bushing chain between ANSI normal chains using curl bushings.
35: A ANSI typical bushing chain ideal for tiny precision machines that call for large power.
