RS ROLLER CHAIN RS11 ˜ RS240 Longer Wear Life Higher Horsepower Ratings Greater Fatigue Strength U.S. Tsubaki Roller Chain lasts up to U.S. Tsubaki ASME/ANSI Chains handle U.S. Tsubaki ASME/ANSI Chains are twice as long as our previous chain in up to 33 percent more horsepower so you designed to have higher fatigue strength. many applications. Advanced technology can increase drive performance without The wider waist of the link plates puts allows us to combine the strength, increasing chain size. In fact, depending more metal where you need it — running durability, and reliability of a solid bushing on your application, you may be able to your application. There is less downtime with our patented lube groove on the transmit the same horsepower with a because chains operate longer. Operating inner surface of sizes RS80 through smaller, less costly chain. The costs are reduced because chains RS140. The solid bushings are precise improvement comes from a U.S. Tsubaki perform more efficiently. These benefits round cylinders, which means better exclusive ring coining process for the slip go right to your bottom line. contact between the pin and bushing. The fit connecting link and special processing lube grooves hold oil where chain needs on the two-pitch offset link. S-N Curve it most. The result is longer lasting chain.

Save Time & Money Wear in the pin-bushing joint can lead to elongation and replacement. U.S. Tsubaki’s ASME/ANSI Chains have a patented lube groove that holds lubricant right where it’s needed — in the pin-bushing joint. Tsubaki chains last longer, reducing maintenance, operating, and replacement costs.

APPLICATIONS

Roller chains can be operated at speeds of up to 10,000 rpm. Even at high speeds, is quieter and smoother than a drive. You never have to worry about slippage as you would with a .

Roller chains are inherently elastic. Compared with gear drives, they soften shock and absorb vibration. They can be used in machines which are subjected to great shock or which constantly move or vibrate. Both the machine’s body and bearing parts are protected against damage. A - DRIVE CHAINS
