ABSTRACT:
A linear bearing assembly is disclosed wherein a plurality of roller members continuously circulate to provide area-to-area contact between the load bearing surfaces. A stationary member of the assembly is an elongated member such as a shaft having a curvilinear bearing surface preferably of convex cylindrical curvature. A bearing race which substantially surrounds the cross section of the shaft has in its interior a plurality of bearing surfaces of substantially the same curvature as the bearing surface of the shaft. The roller members are configured to be complementary to the bearing surfaces of the shaft and of the race, and to roll between said bearing surfaces. The race transmits the load carrying forces to a bearing housing to which an object, such as a machine part, is mounted. The bearing race and the housing jointly comprise channels wherethrough the rollers continuously return to occupy their operative positions between the bearing surfaces of the race and the shaft.
