Abstract
A bearing structure includes a cylindrical first member (), and a second member () received in the first member. The first member is made of ceramic sintered material. The first member defines a first axle hole (), and the first axle hole has a first radius. A chamber () is transversely defined through a middle portion of the first member, the chamber receiving the second member therein. The second member is made of metallic sintered material. The second member defines a second axle hole (), and the second axle hole has a second radius. The first radius of the first axle hole is less than the second radius of the second axle hole. A shaft () is rotatably received in the first and second axle holes. When the shaft deviates from a central axis of rotation, the shaft only contacts the first member at the first axle hole.
