The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response on the demands for smaller sized chains lately for higher engineering machinery this kind of as workplace equipment, medical machines and industrial robots, we deliver 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 like a high-power version of 15. These substantial precision chains are produced below significant high-quality control specifically expected for small sizes, taking dress in resistance also into consideration.
Selection of chain
Refer for the “Low-speed selection”. Nonetheless, the chain operation speed is often set considerably large determined by the type of lubrication as proven in the table under.
Connecting hyperlinks and offset links
R connecting backlinks are used for modest pitch chains. Nonetheless, because their power is decrease than that of the base chain, and because the clip is prone to come off in large velocity operation, using connecting hyperlinks just isn’t recommended. Use a loop chain without having attaching connecting backlinks.
Offset backlinks can be found for chains other than 15 and 15H1, but their use isn’t advised for your identical motive as stated for that R Connecting links.
Working velocity and variety of lubrication
15: A high precision mini-pitch bushing chain that’s smaller than a compact drive chain for general applications, 25
25: Smallest bushing chain amid ANSI conventional chains applying curl bushings.
35: A ANSI common bushing chain suitable for little precision machines that demand high strength.
