  1. Steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties. It is widely used in automotive applications such as compressors, steering gear, power steering, pedal bearings, king-pin bushes, tailgate pivots, mechanical handling and lifting equipment, hydraulic motors, agricultural machinery etc.

  2. Sintered bronze lazer: God wear resistance and excellent load carrying capacity.

  3. Steel backing:Setting the foundation of the bushings,the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
