The smallest chain complying to ANSI is 25 of six.35 mm pitch. Having said that, in response to the demands for smaller chains in recent times for substantial technologies machinery this kind of as office products, health-related machines and industrial robots, we offer 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 as being a high-power edition of 15. These higher precision chains are manufactured below significant quality control specifically necessary for modest sizes, taking put on resistance also under consideration.
Selection of chain
Refer to the “Low-speed selection”. On the other hand, the chain operation pace could be set substantially higher according to the sort of lubrication as proven within the table beneath.
Connecting hyperlinks and offset links
R connecting backlinks are used for compact pitch chains. Even so, since their strength is lower than that from the base chain, and because the clip is likely to come off in large pace operation, using connecting backlinks is not advisable. Use a loop chain without attaching connecting back links.
Offset back links are available for chains apart from 15 and 15H1, but their use is just not recommended for that similar cause as stated for your R Connecting back links.
Working pace and variety of lubrication
15: A high precision mini-pitch bushing chain that’s smaller than a compact drive chain for basic applications, 25
25: Smallest bushing 
chain between ANSI typical chains working with curl bushings.
35: A ANSI conventional bushing chain suitable for tiny precision machines that demand high strength.
