The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nonetheless, in response on the demands for smaller chains in recent years for higher technologies machinery this kind of as office tools, healthcare machines and industrial robots, we give 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 like a high-power model of 15. These large precision chains are manufactured under severe high quality manage primarily demanded for compact sizes, taking put on resistance also into account.
Variety of chain
Refer to the “Low-speed selection”. Nevertheless, the chain operation speed can be set significantly high determined by the kind of lubrication as shown in the table beneath.
Connecting hyperlinks and offset links
R connecting hyperlinks are utilised for little pitch chains. Nevertheless, since their power is reduce than that with the base chain, and because the clip is likely to come off in substantial speed operation, using connecting links is just not suggested. Use a loop chain with out attaching connecting links.
Offset hyperlinks are available for chains besides 15 and 15H1, but their use isn’t encouraged for that very same motive as stated for the R Connecting hyperlinks.
Working velocity and variety of lubrication
15: A high precision mini-pitch bushing chain that is smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain amongst ANSI typical chains using curl bushings.
35: A ANSI conventional bushing chain ideal for tiny precision machines that demand large strength.
