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.
