Now available from APMS , the new Hitachi SBR-Prime solid bushing and roller chain offers an up to 30% increase in Maximum Allowable Load.

In 2009 Hitachi went into full production of the new SBR-Prime series roller chain across the standard range. Hitachi introduced new innovations in manufacturing technologies and part processing, which led to the development of this new SBR-Prime series roller chain.

Hitachi's new SBR-Prime solid bushing and roller chains have a longer wear life than their predecessor.

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

These new SBR-Prime solid bushing and roller chains also have a wear life up to two to three times longer than curled bushings. The curled, split bushings have a seam where tiny space allows lubricant leakage resulting in shorter wear life. Solid bushing and roller chain has no seam resulting in lower bearing pressure. This allows the bushings to retain lubrication, resulting in a much longer wear life.

Solid busing and roller chain is cold-forged from steel rod. This cold-forming process also works with the molecular structure (grain) of the steel running lengthwise in the bushings thereby increasing fatigue strength as well as preventing bushings from breaking.

Hitachi solid bushing and roller chain improves performance of transmission with minimising elongation for long periods of time.
