Sliding bearing is steel plate as the base, the middle spherical sintered bronze powder, the surface rolling PTFE and lead mixture, is rolled from the sliding bearing: and has a small coefficient of friction, wear and corrosion resistance Good and no oil lubrication characteristics. The use of the product has to reduce costs, reduce the mechanical volume, to avoid bite-axis phenomenon and reduce the mechanical noise and so on. It has been widely used in sliding parts of various machinery, such as printing presses, textile machines, tobacco machines, fitness machines, hydraulic hand trucks, micro motors, automobiles, motorcycles and agricultural and forestry machinery. Its advantages are obvious, with good wear resistance, the friction coefficient is small, long service life characteristics. Can make machinery reduce vibration, reduce noise, prevent pollution, improve working conditions. For the grinding axis of the hardness requirements of low, unadjusted shaft can be used, thereby reducing the processing of the relevant parts difficult. Static and dynamic friction coefficient similar to low speed to eliminate the crawl, so the use of the industry is a lot of its position is also very important. So it's development prospects are very good, and later will also have better performance in our lives.
