The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Having said that, in response to your demands for smaller sized chains in recent years for high technologies machinery such as office gear, healthcare machines and industrial robots, we give 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as being a high-power edition of 15. These large precision chains are manufactured beneath severe good quality control particularly essential for smaller sizes, taking put on resistance also into account.
Selection of chain
Refer to the “Low-speed selection”. However, the chain operation speed is usually set substantially substantial according to the type of lubrication as proven in the table below.
Connecting links and offset links
R connecting hyperlinks are used for modest pitch chains. Nevertheless, because their strength is reduce than that from the base chain, and since the clip is likely to come off in large speed operation, the use of connecting back links will not be suggested. Use a loop chain with no attaching connecting back links.
Offset links can be found for chains other than 15 and 15H1, but their use is not really proposed for your exact same reason as stated for the R Connecting hyperlinks.
Operating velocity and kind of lubrication
15: A large 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 regular chains working with curl bushings.
35: A ANSI typical bushing chain ideal for small precision machines that call for large power.
