The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nonetheless, in response for the demands for smaller sized chains in recent years for substantial engineering machinery this kind of as workplace equipment, healthcare machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as a high-power version of 15. These large precision chains are produced below extreme excellent management in particular necessary for modest sizes, taking put on resistance also into consideration.
Collection of chain
Refer to the “Low-speed selection”. Nevertheless, the chain operation pace is usually set considerably high according to the kind of lubrication as proven inside the table under.
Connecting links and offset links
R connecting back links are employed for tiny pitch chains. Having said that, given that their strength is reduced than that with the base chain, and since the clip is prone to come off in high speed operation, the usage of connecting back links is not advisable. Use a loop chain without the need of attaching connecting backlinks.
Offset links are available for chains besides 15 and 15H1, but their use just isn’t advisable for your similar cause as stated for that R Connecting backlinks.
Working velocity and variety of lubrication
15: A high precision mini-pitch bushing chain which is smaller sized than a compact drive chain for standard applications, 25
25: Smallest bushing chain between ANSI standard chains employing curl bushings.
35: A ANSI normal bushing chain ideal for small precision machines that demand substantial strength.
