The smallest chain complying to ANSI is 25 of 6.35 mm pitch. However, in response to the demands for smaller sized chains in recent times for higher technology machinery this kind of as workplace products, healthcare machines and industrial robots, we deliver 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as a high-power version of 15. These higher precision chains are produced underneath severe high quality control in particular required for tiny sizes, taking dress in resistance also into account.
Selection of chain
Refer to your “Low-speed selection”. Nonetheless, the chain operation pace might be set significantly large according to the type of lubrication as shown in the table below.
Connecting links and offset backlinks
R connecting backlinks are applied for modest pitch chains. Having said that, because their strength is decrease than that in the base chain, and because the clip is more likely to come off in higher pace operation, using connecting links just isn’t encouraged. Use a loop chain without having attaching connecting links.
Offset backlinks are available for chains other than 15 and 15H1, but their use is just 
not suggested to the exact same cause as stated for that R Connecting hyperlinks.
Working pace and variety of lubrication
15: A substantial precision mini-pitch bushing chain that’s smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain among ANSI conventional chains utilizing curl bushings.
35: A ANSI normal bushing chain ideal for little precision machines that call for high power.
