Brass & steel bushing

Brass & steel bushing(SCA) SCA series products can be widely used under high temperature and high load with low speed conditions, such as successive casting machinery, mineral machinery, injection molding machinery, dock machinery and so on. Material Properties 1) Combined with the wear resistance of copper alloy and high mechanical strength properties of steel. 2)The different coefficient of friction of the inner and outer material can protect the axil and rotating movement of the bushing in the housing under extremely high load with low speed. 3)Compare with purebrass bushing, the cost is reduced obviously. 4)SCA material have same characteristic as pure brass bushing, suitable for wide temperature range, different oil condition. 5)SCA have better mechanical load performance compare with brass material, especially the impact strength. SCACseries products breaks through the limit of lubrication depending on oil film. During application, oil and powder will be formed by friction heat between solid lubricant and shaft, which can portect shaft from wearing and keep good lubrication perfomance. It is mainly used in rocker arm, cylinder of bull dozer under heavy load and high temperature or low speed and heavy load. Its biggest advantage is good anti-seizing performance even without oil lubrication.
