Product Description Sintered bushing, with tip bushing, square bushing, middle cover bushing, sealing bushing, spacer bushing, straight barrel bushing, mechanical equipment bushing Powder metallurgy oil-impregnated bushings are made of iron powder as raw materials, pressed by molds, sintered at high temperature and then shaped.  Its matrix has fine and evenly distributed pores, which are formed into an oil-containing state after being vacuum-impregnated with lubricating oil. The product has the characteristics of short-term no oil lubrication, low cost of use, and variable inner and outer diameters. It is suitable for use in places with medium speed and low load. Products are widely used in household appliances, power tools, textile machinery, chemical machinery, automobile industry, etc. Low cost: Powdermetallurgy technology can be compacted into final size and does not require post-learning machining, which can greatly save metal materials and reduce product costs. Powder metallurgy bushing advantages: low noise, wear resistance Customized processing: It can be processed into straight bushings, flanged flanged bushings, gaskets, sliders, non-standard shaped parts, etc., and supports non-standard product customization.
