摘要：
A bearing assembly for a worm drive supporting the worm of the worm drive with washer-shaped thrust slide bearings and bush-shaped radial slide (sintered oil-containing bearings) bearings. The thrust slide bearings are made of a resin containing 95 to 99.9 wt % of polyetheretherketone resin, which is an aromatic polyetherketone resin. Wear of the thrust slide bearings is reduced and its durability is improved, thereby preventing vibration and noise of the worm drive as well as improving its durability.
