The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response on the demands for smaller sized chains lately for higher technological innovation machinery such as office equipment, healthcare 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 under severe excellent control particularly necessary for little sizes, taking dress in resistance also into account.
Selection of chain
Refer to the “Low-speed selection”. However, the chain operation pace is often set substantially higher dependant upon the kind of lubrication as proven in the table below.
Connecting back links and offset hyperlinks
R connecting backlinks are utilised for little pitch chains. Having said that, considering the fact that their strength is decrease than that of your base chain, and since the clip is likely to come off in substantial speed operation, the usage of connecting backlinks is not suggested. Use a loop chain with no attaching connecting links.
Offset hyperlinks are available for chains aside from 15 and 15H1, but their use is not really advised for that same motive as stated for your R Connecting back links.
Operating speed and kind of lubrication
15: A higher precision mini-pitch bushing chain which is smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain among ANSI normal chains making use of curl bushings.
35: A ANSI common bushing chain suitable for compact precision machines that need large strength.
