Smaller Pitch Chain

The smallest chain complying to ANSI is 25 of 6.35 mm pitch. Nevertheless, in response for the demands for smaller sized chains in recent times for high technologies machinery such as office tools, health-related machines and industrial robots, we give 15 of 4.7625 mm (3/16 inch) pitch and also 15H1 as a high-power version of 15. These high precision chains are produced beneath significant top quality management specially demanded for small sizes, taking wear resistance also under consideration.
Choice of chain
Refer to your “Low-speed selection”. Even so, the chain operation speed can be set substantially higher depending on the sort of lubrication as shown inside the table below.
Connecting links and offset back links
R connecting backlinks are used for modest pitch chains. On the other hand, since their power is lower than that with the base chain, and because the clip is prone to come off in high speed operation, using connecting hyperlinks isn’t encouraged. Use a loop chain without attaching connecting backlinks.
Offset backlinks can be found for chains besides 15 and 15H1, but their use is not really suggested to the very same motive as stated for that R Connecting back links.
Operating velocity and type of lubrication
15: A large precision mini-pitch bushing chain that may be smaller sized than a compact drive chain for basic applications, 25
25: Smallest bushing chain among ANSI normal chains making use of curl bushings.
35: A ANSI regular bushing chain appropriate for small precision machines that require high power.
