The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Even so, in response towards the demands for smaller 
chains in recent years for large technologies machinery this kind of as workplace tools, healthcare machines and industrial robots, we present 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 like a high-power model of 15. These higher precision chains are manufactured under severe excellent management especially expected for small sizes, taking put on resistance also into account.
Choice of chain
Refer on the “Low-speed selection”. Nonetheless, the chain operation pace may be set significantly large depending on the sort of lubrication as proven in the table under.
Connecting links and offset backlinks
R connecting backlinks are made use of for compact pitch chains. However, considering that their strength is decrease than that of the base chain, and because the clip is more likely to come off in high pace operation, the use of connecting back links will not be encouraged. Use a loop chain devoid of attaching connecting back links.
Offset hyperlinks are available for chains apart from 15 and 15H1, but their use is not advisable for your very same explanation as stated to the R Connecting backlinks.
Operating pace and kind of lubrication
15: A substantial precision mini-pitch bushing chain that is definitely smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain between ANSI common chains applying curl bushings.
35: A ANSI standard bushing chain ideal for smaller precision machines that demand higher power.
