The smallest chain complying to ANSI is 25 of 6.35 mm pitch. However, in response to the demands for smaller chains lately for substantial technological innovation machinery this kind of as workplace products, medical machines and industrial robots, we provide 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power model of 15. These large precision chains are manufactured under severe top quality management especially necessary for modest sizes, taking dress in resistance also into account.
Variety of chain
Refer on the “Low-speed selection”. Nevertheless, the chain operation pace might be set considerably substantial depending on the sort of lubrication as proven inside the table under.
Connecting links and offset links
R connecting hyperlinks are employed for smaller pitch chains. Nevertheless, due to the fact their power is reduce than that with the base chain, and since the clip is likely to come off in large pace operation, the usage of connecting links is not advisable. Use a loop chain with no attaching connecting links.
Offset backlinks can be found for chains besides 15 and 15H1, but their use will not be suggested for your identical cause as stated to the R Connecting 
back links.
Operating speed and variety of lubrication
15: A high precision mini-pitch bushing chain that is smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI normal chains working with curl bushings.
35: A ANSI standard bushing chain ideal for smaller precision machines that need higher power.
