  - Higher safety factor is gained
  - Downsizing to the 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

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 an astringently 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 a 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 a much longer wear life.

Reliable Performance

• SBR is cold-forged from steel rod.
• The 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 the performance of transmission with lesser elongation for a long period of time.
