The smallest chain complying to ANSI is 25 of 6.35 mm pitch. On the other hand, in response to the demands for smaller sized chains lately for large technological innovation machinery this kind of as office equipment, medical machines and industrial robots, we supply 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 being a high-power model of 15. These higher precision chains are manufactured below significant good quality control specifically required for little sizes, taking put on resistance also under consideration.
Choice of chain
Refer to the “Low-speed selection”. However, the chain operation speed is usually set considerably substantial determined by the sort of lubrication as shown during the table beneath.
Connecting back links and offset links
R connecting links are made use of for tiny pitch chains. Having said that, considering that their strength is lower than that of your base chain, and since the clip is likely to come off in substantial speed operation, the usage of connecting links is not proposed. Use a loop chain with no attaching connecting links.
Offset backlinks can be found for chains other than 15 and 15H1, but their use will not be recommended to the similar purpose as stated for the R Connecting links.
Working speed and kind of lubrication
15: A large precision mini-pitch bushing chain that is smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI typical chains applying curl bushings.
35: A ANSI standard bushing chain appropriate for modest precision machines that call for substantial power.
