The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Having said that, in response towards the demands for smaller sized chains in recent times for large engineering machinery such as office products, health-related machines and industrial robots, we present 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power edition of 15. These higher precision chains are produced underneath significant excellent manage specially essential for tiny sizes, taking put on resistance also into account.
Selection of chain
Refer towards the “Low-speed selection”. Having said that, the chain operation speed can be set significantly higher dependant upon the kind of lubrication as proven in the table below.
Connecting backlinks and offset hyperlinks
R connecting hyperlinks are applied for tiny pitch chains. Nonetheless, due to the fact their power is reduce than that on the base chain, and since the clip is likely to come off in large velocity operation, using connecting backlinks is not really advisable. Use a loop chain without the need of attaching connecting hyperlinks.
Offset back links are available for chains aside from 15 and 15H1, but their use just isn’t encouraged for your similar cause as stated for that R Connecting back links.
Working speed and sort of lubrication
15: A large precision mini-pitch bushing chain that is definitely smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain amongst ANSI normal chains applying curl bushings.
35: A ANSI conventional bushing chain appropriate for smaller precision machines that require high strength.
