Wear of Steel Journals during Friction over Bronze and over a Plastic with a Solid Filler,

Abstract

The weight loss by attrition of a steel journal rotating in a metal bearing lined with an epoxy resin was 2-7 times less than the wear of a journal in a bronze bearing. Both bearings were continuously lubricated, the contact pressure was 50 to 100 kg-cm-2, and the surface slippage rate was constant at 0.9 m per sec. The bronze bearing is similar to 4 times harder than the epoxy resin bearing, which in operation is slightly and reversibly deformed due to shearing stress imposed by the journal, increasing the actual contact area and therefore reducing the contact pressure.
