All of our chain products have gone through stringent process measures for Best Quality! This includes heat treatment, which ensures the optimum ware life and toughness for all component parts. Solid hardened and shot peened precision rollers are standard on most of our chains. The bushings provide a smooth roller bearing effect reducing the impact load as the chain engages the sprockets tooth. During chain assembly, all chain components are oriented to ensure pins, bushings, and side plates are correctly positioned for optimum chain strength and long life. Assembled chains are then dipped in a hot lubricant. This lubrication and the process in which it is applied greatly improve the ware life capacity of the chain and further protect it from the effects of the environment.
