SY ASA Roller Chain Heavy Simplex

• 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.

About Heavy Series Roller Chain (H Series)

• SY H-series roller chains are provided with greater shock and wear resistance and high breaking strength for general purpose applications.
• The side plate thickness is equal to the next larger ANSI roller chains and through-hardened high-tensile structural steel pins realize strong power transmission in limited equipment space, showing excellent shock absorption and fatigue strength and high ultimate strength of as much as 110-120 percent.
• Single roller chains of this series run on standard single roller chain sprockets.

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.
