SY ASA Roller Chain Side Bow Simplex Strand

  • 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 Side Bow Chain

  • SY Side Bow chains provide extra clearance between pins, bushings, and link plates to allow freedom of operation around a curve or twist.
  • The basic dimensions and quality are the same as those of ANSI standard roller chains.
  • Side bow chain is widely used for live roll conveyors, and with attachments to convey material around curves.
  • For identification, the suffix SB is added to the number.

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.
