The smallest chain complying to ANSI is 25 of six.35 mm pitch. Nevertheless, in response to the demands for smaller sized chains lately for higher technologies machinery this kind of as workplace tools, healthcare machines and industrial robots, we offer 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 as being a high-power version of 15. These high precision chains are manufactured beneath severe quality manage particularly needed for small sizes, taking put on resistance also into account.
Variety of chain
Refer on the “Low-speed selection”. Nonetheless, the chain operation speed might be set significantly high according to the kind of lubrication as shown within the table below.
Connecting links and offset backlinks
R connecting back links are used for modest pitch chains. Having said that, considering that their power is reduce than that on the base chain, and since the clip is likely to come off in high pace operation, the usage of connecting back links is just not encouraged. Use a loop chain without the need of attaching connecting back links.
Offset links are available for chains apart from 15 and 15H1, but their use will not be proposed for the identical reason as stated to the R Connecting back links.
Working velocity and type of lubrication
15: A higher precision mini-pitch bushing chain that is smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain amid ANSI common chains employing curl bushings.
35: A ANSI normal bushing chain suitable for tiny precision machines that call for higher strength.
