Ultra Super Series

g8-logo

ULTRA SUPER Series offer longer wear life, higher shock load resistance and higher tensile strength than any other Tsubaki roller chain. The pins are through-hardened and the pin holes are critically formed and ball drifted. The diameter of the pins has been increased.

This chain is well suited for applications where there are space limitations. The heavy duty construction of the ULTRA SUPER Series chain allows it to replace chains up to two pitch sizes larger ANSI G8 Series chain. It is best suited for low speed operating conditions up to 50 m/min.
