The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response on the demands for smaller sized chains in recent years for high engineering machinery this kind of as office gear, health care machines and industrial robots, we provide 15 of 4.7625 mm (3/16 inch) pitch and in addition 15H1 as being a high-power model of 15. These higher precision chains are produced under extreme high-quality management particularly demanded for little sizes, taking dress in resistance also into account.
Choice of chain
Refer towards the “Low-speed selection”. Nonetheless, the chain operation velocity can be set considerably high according to the sort of lubrication as proven inside the table beneath.
Connecting back links and offset links
R connecting hyperlinks are utilised for tiny pitch chains. However, considering the fact that their power is decrease than that of the base chain, and because the clip is more likely to come off in high speed operation, using connecting back links is not proposed. Use a loop chain without attaching connecting back links.
Offset hyperlinks can be found for chains apart from 15 and 15H1, but their use just isn’t recommended for that exact same reason as stated for that R Connecting links.
Operating speed and type of lubrication
15: A substantial precision mini-pitch bushing chain that is definitely smaller than a compact drive chain for common applications, 25
25: Smallest bushing chain amid ANSI regular chains employing curl bushings.
35: A ANSI regular bushing chain ideal for small precision machines that need high power.
