The smallest chain complying to ANSI is 25 of 6.35 mm pitch. On the other hand, in response on the demands for smaller sized chains in recent times for high engineering machinery this kind of as workplace tools, medical machines and industrial robots, we provide 15 of four.7625 mm (3/16 inch) pitch as well as 15H1 as being a high-power edition of 15. These higher precision chains are produced below severe high quality management specifically required for tiny sizes, taking put on resistance also into consideration.
Choice of chain
Refer to your “Low-speed selection”. Nonetheless, the chain operation velocity is often set significantly higher determined by the kind of lubrication as shown from the table under.
Connecting backlinks and offset backlinks
R connecting hyperlinks are used for modest pitch chains. Having said that, because their strength is lower than that in the base chain, and since the clip is likely to come off in substantial pace operation, the usage of connecting hyperlinks will not be encouraged. Use a loop chain without attaching connecting backlinks.
Offset links are available for chains other than 15 and 15H1, but their use isn’t advised to the same reason as stated for the R Connecting hyperlinks.
Operating velocity and kind of lubrication
15: A large precision mini-pitch bushing chain that may be smaller than a compact drive chain for general applications, 25
25: Smallest bushing chain among ANSI common chains working with curl bushings.
35: A ANSI typical bushing chain ideal for compact precision machines that demand higher power.
