The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Even so, in response for the demands for smaller sized chains in recent years for substantial engineering machinery this kind of as office tools, health-related machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as being a high-power edition of 15. These higher precision chains are manufactured underneath severe high quality management especially required for little sizes, taking put on resistance also into consideration.
Choice of chain
Refer on the “Low-speed selection”. However, the chain operation velocity might be set considerably higher determined by the type of lubrication as shown while in the table beneath.
Connecting links and offset hyperlinks
R connecting back links are made use of for tiny pitch chains. Even so, considering the fact that their strength is decrease than that in the base chain, and because the clip is likely to come off in large speed operation, the usage of connecting hyperlinks will not be advised. Use a loop chain devoid of attaching connecting hyperlinks.
Offset backlinks can be found for chains aside from 15 and 15H1, but their use is not really suggested to the very same explanation as stated for that R Connecting hyperlinks.
Operating velocity and variety of lubrication
15: A higher precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain between ANSI common chains making use of curl bushings.
35: A ANSI normal bushing chain appropriate for modest precision machines that require higher power.
