These patent-pending bushings are formed from strip steel that is formed and die-sized around a precision mandrel to create a bushing with excellent roundness, superior strength, and very little wall thickness variation. This reduces wear (stretching), reducing sprocket wear and power losses from improper sprocket/chain engagement. 120 Links.
