Abstract: A plain bearing assembly including an inner bearing, outer bearing, and at least one intermediate bearing. The inner bearing has an annular inner bearing surface. The intermediate bearing includes a ring bearing having an annular inner and outer surface. The intermediate bearing also includes bushes rotatably mounted about the inner bearing and rotatable with respect to the bearing ring and outer bearing. The bushes provide a bearing surface adjacent to the annular inner bearing surface of the bearing ring and providing a bearing surface adjacent to the annular outer bearing surface of the bearing ring.

Abstract: The invention relates to a bearing for a shaft comprising a first bearing member mountable on the shaft to be fixed thereto, and a second bearing member rotatably mountable about the coaxial with the first bearing member to define at least two annular bush receiving recesses, wherein the two or more annular bush receiving recesses are at least partially separated by at least one internal locating projection projecting from either the first or the second bearing member, and at least two annular bush members locatable one in each of the bush receiving recesses each said annular bush membering being adapted to dissipate heat during operation of the bearing by oscillating between a condition in which the annular bush member is stationary with respect to the first bearing member and rotatable with respect to the second bearing member is stationary with respect to the second bearing member and rotatable with respect to the first bearing member.
