Material Characteristics

(Sintered Copper Lead)

SAE-792

 

This material is best suited for bushings and washers to high impact and vibratory loads. In most cases, it operates best with a hardened shaft.

SAE-49

 

This is a bearing material designed exclusively for high load. The material is plated with a unique trimetal overlay and nickel dam.

SAE-794

 

This material is employed for bushings and thrust washers applications subject to intermediate impacts and vibratory loads. It has certain degree of embedability and it is suitable for higher speed and load.
