Abstract
A thrust bearing having a sliding surface composed of a resin composition which comprises 10 to 45% by weight of a carbon fiber, 0.1 to 30% by weight of a polytetrafluoroethylene, 0.1 to 20% by weight of a graphite having an oil absorption of 70 to 500 ml/100 g, the balance being substantially an aromatic polyetherketone resin wherein the total content of the carbon fiber, the polytetrafluoroethylene and the graphite is not more than 65% by weight. The sliding surface of the above thrust bearing is excellent in wear resistance and low in friction coefficient at the time of starting.
