The smallest chain complying to ANSI is 25 of 6.35 mm pitch. On the other hand, in response to the demands for smaller chains lately for higher engineering machinery such as office tools, health-related machines and industrial robots, we offer 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 being a high-power model of 15. These higher precision chains are manufactured below serious good quality management especially needed for compact sizes, taking wear resistance also into account.
Choice of chain
Refer for the “Low-speed selection”. Even so, the chain operation pace is usually set considerably substantial determined by the type of lubrication as shown from the table below.
Connecting hyperlinks and offset backlinks
R connecting backlinks are utilized for modest pitch chains. However, since their power is reduced than that of your base chain, and since the clip is more likely to come off in higher velocity operation, the use of connecting back links isn’t advisable. Use a loop chain without having attaching connecting backlinks.
Offset hyperlinks can be found for chains aside from 15 and 15H1, but their use will not be proposed for that same purpose as stated to the R Connecting back links.
Working velocity and sort of lubrication
15: A higher precision mini-pitch bushing chain that may be smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI standard chains utilizing curl bushings.
35: A ANSI standard bushing chain appropriate for modest precision machines that demand large power.
