ABSTRACT:
A bearing comprises a metallic outer tube having a flange, a inner tube of resin having a flange, radial rollers, thrust balls and a collar. A plurality of roller receiving grooves are formed on the outer periphery of the inner tube, while a plurality of roller receiving recesses are formed on the flange of the inner tube. The receiving grooves are formed in parallel relation to the bearing axis. The receiving recesses are formed circumferentially in concentric relation to the bearing axis. Each of the rollers received respectively within the receiving groove is rotatable. Grease is possibly apply to an outer peripheral surface of the inner tube body and a flange surface thereof. The cylindrical outer tube covering the entirety has both ends which are bent toward the axis. As corrosion countermeasure, it is preferred to form metallic parts of the bearing with stainless steel.
