Sliding bearing is a plate for the matrix, between sintered bronze spherical powder, the surface of rolling polytetrafluoroethylene (PTFE) and lead compounds, formed by the rolling of the sliding bearing. With a small coefficient of friction, wear resistance, corrosion resistance and good oil-free lubrication characteristics. Using the product can reduce costs, reduce machine size, to avoid bites axis situation and reduce the advantages of mechanical noise. Has been widely applied to various mechanical sliding parts such as gear pumps, hydraulic components, pneumatic components, printing machine, textile machine, tobacco machines, fitness equipment, hydraulic loader, micro-motors, automobiles, motorcycles and agricultural and forestry industry machinery.Static250N/mm2Max.LoadDynamic140N/mm2 Oscillating60N/mm2PVDry3.6N/mm2.m/sPV limitOil50N/mm2.m/sTemp.limit-195+280Friction Coeff. 0.030.20μ Dry 2m/sSpeep limitOil 5m/sThermal conductivity 2.41Kcal/M.br.cCoeff.
