U.S. TSUBAKI RS ROLLER CHAIN
Heat Treatment Ensures Durability Chain durability depends to a great extent on the heat-treatment of the various parts. The use of the most advanced heat-treatment methods and equipment guarantees that U.S. Tsubaki roller chains are highly durable.
Assurance of Greater Fatigue Strength The wider waist of U.S. Tsubaki link plates ensures greater fatigue strength for all chain sizes. Fatigue strength (max. allowable load) of each size can be found in this catalog.
5) Improved U.S. Tsubaki roller chain sizes RS80 through RS140 have the patented PerforMax™ solid lube groove bushings and last up to twice as long in many applications. The lube groove retains oil at the critical pin- bushing contact point, extending the life of the chain.

Longer Wear Life & Less Initial Adjustment 1) U.S. Tsubaki has decreased initial wear elongation to 0.01% and increased wear life by up to twice as long in many applications. Where initial elongation is a problem, as in precision applications or when you simply demand the best, U.S. Tsubaki roller chain is the solution. 2) Our original prelubricant minimizes wear elongation to enable a vast increase in the chain's wear life. 3) U.S. Tsubaki’s lube groove bushings hold oil at the pin-bushing interface, extending the working life of the chain.

Shot Peened Parts Link plates and rollers are shot peened for greater fatigue strength.
Prelubrication A special lubrication is applied by U.S. Tsubaki to bearing surfaces by hot dipping to extend chain life and reduce maintenance costs.
Factory Preloading U.S. Tsubaki roller chains are continuously preloaded on multi-sprockets after final assembly as shown below. This results in minimum initial stretch.

A Completely Automated Manufacturing Process
The manufacture of U.S. Tsubaki roller chains employs advanced, automated techniques. The specialized equipment used in each process ensures that all parts are uniform and high quality. The photo below shows the automated positioning of curled bushings.
4) Micron control has enabled U.S. Tsubaki to produce perfectly straight bushings and significantly reduce wear elongation during initial operation.
