Low Noise Wrapped Bronze Bushings Wear Resistant Sintered Copper Powdered
1. Product Description
Low Noise Wrapped Bronze Bushings Wear Resistant Sintered Copper Powdered is of high safety factor and is particularly appropriate for high teemperature environment where no oil is effcient and where the machine must be under successive long period working condition.This product is widely applied overseas.With the increase of our country's bring-in of the foreign machineries,designers requirement on new abrasive materials and bushings are accordingly increasing.Therefore,our products have a wide application scope and practival value in machinery producion.

3. Application
Low Noise Wrapped Bronze Bushings Wear Resistant Sintered Copper Powdered are widely used in valve, hydraulic industry ,steel metallurgy industry , battery industry etc.
4. Advantages
This series of wear-resisting, low noise, can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.It is of high load capacity and long life.In place of traditional bronze bush,it is more cheap and more compact,also has the advantage of abundant oil storage,easy-to-assembly,machine the compactness etc.
