The smallest chain complying to ANSI is 25 of six.35 mm pitch. Having said that, in response towards the demands for smaller chains in recent times for substantial engineering machinery this kind of as workplace equipment, health care machines and industrial robots, we give 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 as being a high-power edition of 15. These higher precision chains are manufactured below significant top quality control specifically necessary for modest sizes, taking put on resistance also under consideration.
Choice of chain
Refer to your “Low-speed selection”. On the other hand, the chain operation pace could be set substantially large according to the sort of lubrication as proven while in the table beneath.
Connecting hyperlinks and offset links
R connecting backlinks are made use of for little pitch chains. Nonetheless, since their strength is lower than that from the base chain, and because the clip is prone to come off in higher pace operation, using connecting backlinks is not advisable. Use a loop chain without attaching connecting links.
Offset links are available for chains apart from 15 and 15H1, but their use is just not recommended for the exact same cause as stated for your R Connecting back links.
Operating pace and variety of lubrication
15: A higher precision mini-pitch bushing chain that’s smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain between ANSI typical chains working with curl bushings.
35: A ANSI conventional bushing chain appropriate for tiny precision machines that demand high strength.
