The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response for the demands for smaller sized chains lately for substantial engineering machinery this kind of as office gear, health care machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 as a high-power model of 15. These high precision chains are produced under extreme excellent handle especially expected for small sizes, taking dress in resistance also into account.
Selection of chain
Refer to the “Low-speed selection”. Nevertheless, the chain operation pace is usually set considerably high based on the sort of lubrication as proven in the table below.
Connecting back links and offset back links
R connecting hyperlinks are employed for little pitch chains. Having said that, due to the fact their power is decrease than that of your base chain, and because the clip is more likely to come off in substantial speed operation, using connecting backlinks is not really encouraged. Use a loop chain devoid of attaching connecting backlinks.
Offset links can be found for chains apart from 15 and 15H1, but their use isn't proposed to the same motive as stated to the R Connecting back links.
Operating velocity and variety of lubrication
15: A large precision mini-pitch bushing chain that is certainly smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI standard 
chains making use of curl bushings.
35: A ANSI standard bushing chain appropriate for compact precision machines that require substantial power.
