3. Application
Powder Metallurgy Oil-impregnated Bearings For Automobile Compressor Low Cost are widely usde in automobile compressor ,automobile wiper,car door,fan,electrical machinery,chemical machinery etc.
4. Advantages
This type copper bush does not need or only very litle machining, with high usage rate of material.Parts size consistency is good and stable,the precision can reach 0.01mm and the material composition can be adjusted according to the customers’requirement of the parts performance.Due to the die forming, we can customize the complex shape or special profiled parts which the other machining can not do.Because suitable for mass production, the production efficiency is high and the cost is lower than machining. Moreover it is cheap and stable in dimension.
