Sintered Bronze Bushes, Sintered Porous Metal Bearings The bush in Sintered Bronze give a wide range of applications, is realized with a powder of bronzesintered, calibrated and impregnated into specific oil
Oil impregnated is made of tin bronze powder mutallurgy, the bearing by increasing the porosity, oil containing rate be improved; it is long life because of high oil content, and abolition the oil filling felt, therefore, the total production cost reduced.
Bearing forms made to order: cylindrical bushes and flanged bushes with non-standard dimensions, spherical bearings, tubes and rod blanks, customized bearing designs

· Do not need or only very little machining |
· High usage rate of material(more than 95%) |
· Parts size consistency is good and stable. The precision can reach 0.01mm. |
· The material composition can be adjusted according to the customers’requirement of the parts performance. |
· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness. |
· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do. |
· Because suitable for mass production, the production efficiency is high and the cost is lower than machining. |
