OEM Powder metallurgy bushing , high precision, super wear resistance, low noise, powder metallurgy bushings are widely used in packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, all kinds of machine tools and mutual Change the mechanical transmission coupling. In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain degree, the parts must be replaced. Therefore, the designer chooses lower hardness and better wear resistance when designing. The material is the shaft sleeve or bushing, which can reduce the wear of the shaft and the seat. When the shaft sleeve or the sleeve is worn to a certain extent, replace it, which can save the cost of replacing the shaft or the seat.
