The smallest chain complying to ANSI is 25 of six.35 mm pitch. However, in response to the demands for smaller chains lately for higher technologies machinery such as workplace tools, health care machines and industrial robots, we supply 15 of 4.7625 mm (3/16 inch) pitch as well as 15H1 being a high-power model of 15. These high precision chains are produced underneath serious good quality handle specifically demanded for small sizes, taking wear resistance also into account.
Selection of chain
Refer to your “Low-speed selection”. On the other hand, the chain operation velocity could be set substantially large depending on the type of lubrication as shown in the table beneath.
Connecting back links and offset backlinks
R connecting hyperlinks are made use of for small pitch chains. Nonetheless, considering the fact that their strength is reduce than that on the base chain, and because the clip is likely to come off in substantial velocity operation, the use of connecting backlinks is just not recommended. Use a loop chain devoid of attaching connecting links.
Offset back links can be found for chains apart from 15 and 15H1, but their use is not really recommended for the exact same purpose as stated for that R Connecting links.
Working pace and sort of lubrication
15: A large precision mini-pitch bushing chain that may be smaller than a compact drive chain for basic applications, 25
25: Smallest bushing chain amongst ANSI common chains using curl bushings.
35: A ANSI conventional bushing chain appropriate for modest precision machines that require large power.
