Our genuine maintenance free Oilite (SAE 841) Self-Lubricating Sintered Bronze Metric Bearings are the most widely used sintered bronze bearings in industry. Oilite bearings are copper in color and they are made primarily of copper. They are also highly wear-resistant, ductile, conformable and corrosion resistant. Oilite bearings are used in most general purpose applications where moderate speeds and loads are present. PV = 50,000 / P(psi) Static = 8,000 / P(psi) Dynamic = 2,000 / V(sfm) = 1,200.
