The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response towards the demands for smaller chains lately for high technologies machinery this kind of as office equipment, health care machines and industrial robots, we deliver 15 of four.7625 mm (3/16 inch) pitch and also 15H1 like a high-power model of 15. These substantial precision chains are manufactured underneath significant quality management primarily expected for little sizes, taking dress in resistance also into consideration.
Choice of chain
Refer to the “Low-speed selection”. Having said that, the chain operation speed can be set substantially high according to the type of lubrication as shown from the table under.
Connecting hyperlinks and offset hyperlinks
R connecting backlinks are utilized for modest pitch chains. Nevertheless, due to the fact their strength is reduce than that of the base chain, and because the clip is more likely to come off in high speed operation, the usage of connecting hyperlinks just isn’t advisable. Use a loop chain with no attaching connecting backlinks.
Offset links are available for chains aside from 15 and 15H1, but their use is just not encouraged for the similar purpose as stated to the R Connecting hyperlinks.
Operating velocity and variety of lubrication
15: A large precision mini-pitch bushing chain which is smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain among ANSI regular chains using curl bushings.
35: A ANSI conventional bushing chain suitable for modest precision machines that require substantial strength.
