The smallest chain complying to ANSI is 25 of six.35 mm pitch. Even so, in response for the demands for smaller sized chains in recent years for high technologies machinery this kind of as office equipment, healthcare machines and industrial robots, we give 15 of four.7625 mm (3/16 inch) pitch as well as 15H1 being a high-power version of 15. These high precision chains are produced below serious high-quality manage specially expected for smaller sizes, taking put on resistance also into consideration.
Selection of chain
Refer to the “Low-speed selection”. Even so, the chain operation velocity can be set significantly substantial dependant upon the type of lubrication as shown during the table beneath.
Connecting backlinks and offset hyperlinks
R connecting back links are utilised for compact pitch chains. Even so, considering the fact that their power is decrease than that of the base chain, and since the clip is more likely to come off in substantial velocity operation, the use of connecting backlinks just isn’t proposed. Use a loop chain without attaching connecting backlinks.
Offset back links are available for chains apart from 15 and 15H1, but their use is not encouraged to the very same explanation as stated to the R Connecting hyperlinks.
Working velocity and variety of lubrication
15: A large precision mini-pitch bushing chain which is smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI common chains applying curl bushings.
35: A ANSI common bushing chain suitable for small precision machines that demand large power.
