  • Sugiyama Roller Chain is the ultimate roller chain.
  • Sugiyama Chain Manufacturing Co. is the only company in the world that supplies all of its standard chains with solid bushings and solid rollers.
  • This gives SY Chain a longer service life & a higher allowable maximum load.


  • +30% Higher Fatigue Strength
    - Higher safety factor is gained
    - Downsizing to smaller chain is possible in some applications
    - Cost Savings
  • The longest chain life
    - Significantly longer wear
    - Up to 2-3 times longer wear life over curled bushings
    - Reliable performance
  • Choose from 3 different strands: Simplex, Duplex or Triplex.
  • Available in British or American standard.

All About Premium SBR

  • SBR (Solid Bushings and Rollers) chain was created through product development that brought all of our best technologies together.
  • Premium roller chains are made with solid bushings and solid rollers, specially treated pins and bushings, and a stringently controlled heat treatment process.
  • They meet or exceed ANSI roller chain standard B29.1, making it the most suitable selection for almost any application.

Significantly Longer Wear Life

  • Conventional split bushings deform into a barrel shape when side plates are pressed on, leaving only two-point contact area.
  • SBR (Solid Bushings & Rollers) chain has extremely cylindrical inside bushing and roller walls resulting in full contact to disperse bearing pressure.
  • Less pressure ensures excellent wear resistance.

Up to 2-3 times Longer Wear Life Over Curled Bushings Chain

  • The curled, split bushings have a seam where tiny space allows lubricant leakage resulting in shorter wear life.
  • SBR has no seam resulting in lower bearing pressure allowing the bushings to retain lubrication resulting in much longer wear life.

Reliable Performance

  • SBR is cold-forged from steel rod. Cold-forming process also works with the molecular structure (grain) of the steel running lengthwise in the bushings thereby increasing fatigue strength and preventing bushings from breakage.
  • Premium SBR chains improve performance of transmission with lesser elongation for long period of time.
