The smallest chain complying to ANSI is 25 of six.35 mm pitch. Even so, in response to your demands for smaller sized chains in recent times for substantial technology machinery such as workplace tools, medical machines and industrial robots, we present 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power edition of 15. These large precision chains are manufactured beneath severe good quality handle specially demanded for compact sizes, taking put on resistance also under consideration.
Selection of chain
Refer to the “Low-speed selection”. However, the chain operation speed might be set substantially higher depending on the type of lubrication as proven while in the table below.
Connecting links and offset back links
R connecting links are utilized for tiny pitch chains. Nevertheless, considering the fact that their strength is lower than that of your base chain, and since the clip is prone to come off in large velocity operation, the usage of connecting backlinks is just not proposed. Use a loop 
chain without the need of attaching connecting links.
Offset back links are available for chains aside from 15 and 15H1, but their use is just not suggested for that similar purpose as stated for that R Connecting back links.
Operating speed and style of lubrication
15: A high precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain amongst ANSI normal chains using curl bushings.
35: A ANSI normal bushing chain suitable for tiny precision machines that call for higher power.
