Abstract: A two-wheel furniture caster has a body, a shaft projecting horizontally through the body along a shaft axis and having opposite ends projecting axially oppositely from the body, respective wheels rotatable on the ends of the shaft and having outer tread parts axially delimiting a space wholly containing the body and an upright pivot pin having a lower end projecting into the body offset from the shaft axis along a pivot axis. Bearings generally level with and closely juxtaposed with the shaft axis in the body supporting the pivot pin in the body for rotation therein about the pivot axis. A shield ring generally centered on the shaft axis wholly surrounds the body radially relative to the shaft axis, has axially opposite end edges closely juxtaposed with the respective wheels, and is formed with a hole traversed by the pivot pin.

Abstract: The swivel bearing comprises a cup secured on a part of the apparatus and provided with a cylindrical wall which is bent inwardly to hold the outer bearing against the flange on another member, which flange rests upon another set of bearings in the cup.

Abstract: A journal bearing for supporting the hubs of wheels and rollers comprises at least two axially spaced rows of rolling elements between an outer bearing ring and an inner bearing member. The inner bearing member has connecting means at each end to enable the bearing to be fitted to a wheel fork. The inner bearing member also carries sealing means on its axial end portions to protect the rolling elements. These axial end portions may be of reduced external diameter and can project axially beyond the outer bearing ring.
