ANSI Roller Chains Why Tsubaki Chain?
Assurance of Greater Fatigue Strength: The wider waist of the Tsubaki link plates ensures greater fatigue strength for all chain sizes and styles. Fatigue strength (Maximum Allowable Load) of each chain size can be found in the ANSI Chain section of this catalog.
Heat Treatment: Chain durability depends heavily on the proper heat treatment of the wear components. The use of advanced heat-treatment methods allows for Tsubaki roller chains to maintain a high level of durability.

Prelubrication: A special lubrication is applied by hot-dipping the chain in an oil bath prior to packaging. This will help to ensure that the lube penetrates the key friction wear points of the chain.
Longer Wear Life & Less Set-up time: • Tsubaki has decreased initial wear elongation to .01% and increased the life by up to 2x as long in many applications. When there isn’t time to adjust and readjust a chain during installation, Tsubaki roller chains are the very best solution. • Tsubaki uses a special pre-lubrication process that vastly increases chain wear life. • Improved Tsubaki roller chain sizes 80-140 have the patented Performax ™ solid lube groove bushings. By retaining the lube in the grooves of the bushing, it allows lubrication to stay in the key pin and bushing friction point.

Longer Wear Life Tsubaki roller chains last up to twice as long as previously manufactured chains due to the reliability and durability of the solid bushing and patented lube groove design. This technology covers sizes 80-140 in carbon steel chains. The solid bushings are precisely round while the grooves on the inner wall of the bushing holds lubricant where the chain needs it most. The result is a longer lasting chain. Revs Per Minute (RPM) *Ratings are for RS80-RS240 Roller Chains 33% Increase in Horsepower Ratings Previous Tsubaki Chain
Higher Horsepower Ratings Tsubaki ANSI roller chains can handle up to 33-percent more horsepower allowing your application to increase drive performance without increasing chain size. Tsubaki chains may also allow your applicaiton to transmit the same horsepower with a smaller pitch chain. The improvement comes from a ring-coining process for slip-fit style connecting links.
Greater Fatigue Strength Tsubaki chains are designed to have greater fatigue strength. The wider-waist of the link plates puts more metal where it’s needed most. This means less downtime, reduced operating costs, and better application efficiency. These benefits impact your application in one major way - the bottom line.

A Completely Automated Manufacturing Process: The manufacturing of Tsubaki roller chains employs advanced
automated techniques. The specialized equipment used in each process ensures that all parts are uniform and of the highest quality. The adjacent image shows an assembled solid bushing placed in the roller link.
Factory Preloading: Tsubaki roller chains are preloaded using a process that involves the chain, under tension running through a loading table (see below). This allows all key components to seat properly thus eliminating initial set up elongation. This process is
