Abstract
A self-lubricated sliding bearing for a rotary X-ray tube comprises a first bearing member, a second bearing member configured to concentrically enclose a portion of the first bearing member, and a lubricant comprised in a gap between cooperating surfaces of the first bearing member and the second bearing member. The cooperating surface of the second bearing member or the first bearing member comprises a first region comprising a pumping pattern configured to pump the lubricant. The cooperating surface of the second bearing member or the first bearing member comprises a second region having a modified pumping pattern or a smooth surface. The second region is disposed on the cooperating surface of the second bearing member or the first bearing member, such that a bearing force generated by the pumping action of the lubricant opposes a radial load force exerted on the self-lubricated sliding bearing to reduce an eccentricity of a longitudinal axis of the first bearing member with respect to a longitudinal axis of second bearing member.
