The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nonetheless, in response towards the demands for smaller chains in recent years for large technology machinery such as workplace tools, medical machines and industrial robots, we give 15 of four.7625 mm (3/16 inch) pitch and also 15H1 being a high-power version of 15. These substantial precision chains are produced below severe quality control specifically needed for smaller sizes, taking wear resistance also into consideration.
Variety of chain
Refer on the “Low-speed selection”. Having said that, the chain operation velocity may be set substantially large based upon the type of lubrication as proven while in the table under.
Connecting links and offset backlinks
R connecting back links are made use of for modest pitch chains. Nevertheless, given that their strength is reduce than that in the base chain, and since the clip is likely to come off in 
high velocity operation, the use of connecting links just isn’t advised. Use a loop chain without having attaching connecting hyperlinks.
Offset back links are available for chains besides 15 and 15H1, but their use is just not suggested for your very same purpose as stated for your R Connecting backlinks.
Working speed and sort of lubrication
15: A high precision mini-pitch bushing chain that may be smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain between ANSI normal chains using curl bushings.
35: A ANSI normal bushing chain suitable for little precision machines that demand high strength.
