The smallest chain complying to ANSI is 25 of six.35 mm pitch. Having said that, in response for the demands for smaller chains in recent times for high technology machinery this kind of as office gear, healthcare machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as being a high-power model of 15. These substantial precision chains are produced underneath serious good quality management in particular demanded for tiny sizes, taking wear resistance also under consideration.
Variety of chain
Refer for the “Low-speed selection”. Having said that, the chain operation velocity can be set substantially large determined by the sort of lubrication as proven from the table below.
Connecting hyperlinks and offset backlinks
R connecting links are employed for little pitch chains. Even so, due to the fact their power is reduced than that of the base chain, and since the clip is likely to come off in substantial pace operation, the usage of connecting links is just not advisable. Use a loop chain without the need of attaching connecting back links.
Offset backlinks can be found for chains apart from 15 and 15H1, but their use isn’t encouraged for that exact same explanation as stated for the R Connecting backlinks.
Operating pace and type of lubrication
15: A large precision mini-pitch bushing chain that is definitely smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain amid ANSI standard chains working with curl bushings.
35: A ANSI conventional bushing chain suitable for small precision machines that need large power.
