The smallest chain complying to ANSI is 25 of 6.35 mm pitch. However, in response for the demands for smaller chains lately for high engineering machinery this kind of as workplace products, medical machines and industrial robots, we offer 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power version of 15. These high precision chains are produced underneath severe good quality management primarily expected for little sizes, taking put on resistance also into consideration.
Choice of chain
Refer for the “Low-speed selection”. Nevertheless, the chain operation speed may be set substantially high depending on the kind of lubrication as shown while in the table beneath.
Connecting back links and offset links
R connecting back links are utilised for little pitch chains. Nonetheless, due to the fact their strength is reduce than that on the base chain, and because the clip is likely to come off in large speed operation, the use of connecting backlinks is not really proposed. Use a loop chain without having attaching connecting links.
Offset hyperlinks are available for chains apart from 15 and 15H1, but their use will not be suggested for your exact same explanation as stated to the R Connecting links.
Working velocity and variety of lubrication
15: A substantial precision mini-pitch bushing chain that may be smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain among ANSI typical chains applying curl bushings.
35: A ANSI normal bushing chain suitable for compact precision machines that call for large power.
