RS Roller Chain

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. Only two-pitch offset links are available.

  • 1 Single-strand chain. For multiple-strand chain, use larger tensioner.
  • 2 Width between roller link plates (W) is slightly narrower than ANSI standard, however this chain runs on standard sprockets.
