The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response towards the demands for smaller chains lately for substantial technological innovation machinery such as office tools, health care machines and industrial robots, we give 15 of four.7625 mm (3/16 inch) pitch and also 15H1 as a high-power version of 15. These large precision chains are produced beneath extreme good quality manage particularly needed for compact sizes, taking put on resistance also into account.
Choice of chain
Refer for the “Low-speed selection”. Even so, the chain operation pace is usually set significantly high determined by the kind of lubrication as shown from the table beneath.
Connecting hyperlinks and offset backlinks
R connecting back links are utilised for modest pitch chains. Nonetheless, since their power is lower than that from the base chain, and because the clip is likely to come off in large speed operation, the usage of connecting back links is just not advisable. Use a loop chain without having attaching connecting back links.
Offset backlinks are available for chains aside from 15 and 15H1, but their use is not suggested for the exact same purpose as stated to the R Connecting links.
Operating speed and sort of lubrication
15: A higher precision mini-pitch bushing chain that may be smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain between ANSI normal chains utilizing curl bushings.
35: A ANSI standard bushing chain appropriate for compact precision machines that call for substantial power.
