The smallest chain complying to ANSI is 25 of six.35 mm pitch. On the other hand, in response for the demands for smaller chains in recent years for high engineering machinery this kind of as office tools, medical machines and industrial robots, we present 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 like a high-power edition of 15. These higher precision chains are manufactured beneath extreme quality handle primarily required for compact sizes, taking wear resistance also into consideration.
Collection of chain
Refer to your “Low-speed selection”. Having said that, the chain operation speed might be set considerably substantial depending on the sort of lubrication as proven within the table beneath.
Connecting links and offset back links
R connecting backlinks are applied for smaller pitch chains. On the other hand, considering that their strength is reduced than that of the base chain, and because the clip is likely to come off in large velocity operation, using connecting backlinks is not advisable. Use a loop chain with out attaching connecting back links.
Offset back links can be found for chains other than 15 and 15H1, but their use will not be advisable for that same explanation as stated for that R Connecting backlinks.
Operating velocity and kind of lubrication
15: A higher precision mini-pitch bushing chain that is definitely smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain amongst ANSI common chains using curl bushings.
35: A ANSI typical bushing chain ideal for modest precision machines that call for substantial strength.
