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

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.
