The smallest chain complying to ANSI is 25 of 6.35 mm pitch. On the other hand, in response towards the demands for smaller sized chains in recent times for large technological innovation machinery this kind of as workplace gear, health-related machines and industrial robots, we present 15 of four.7625 mm (3/16 inch) pitch and in addition 15H1 as being a high-power version of 15. These substantial precision chains are produced below extreme high-quality control primarily essential for tiny sizes, taking put on resistance also into consideration.
Collection of chain
Refer towards the “Low-speed selection”. Nonetheless, the chain operation pace is often set significantly higher dependant upon the kind of lubrication as shown inside the table under.
Connecting hyperlinks and offset back links
R connecting back links are utilised for tiny pitch chains. On the other hand, considering that their strength is reduced than that of your base chain, and because the clip is prone to come off in higher speed operation, using connecting back links isn’t encouraged. Use a loop chain without attaching connecting backlinks.
Offset links can be found for chains besides 15 and 15H1, but their use is just not advised for your very same explanation as stated for the R Connecting back links.
Working speed and type of lubrication
15: A higher precision mini-pitch bushing chain that is certainly smaller sized than a compact drive chain for general applications, 25
25: Smallest bushing chain among ANSI regular chains working with curl bushings.
35: A ANSI regular bushing chain ideal for little precision machines that call for substantial strength.
