Abstract
A caster has a cylindrical housing defining a cylindrical bore with a pair of spaced apart cord shaped journals in the bore. The journals have aligned openings and a shaft extends in the openings and across the space between the journals. A roller is mounted for rotation on the shaft and in the space between the journals and a bearing is mounted between the roller and the shaft. The bearing is between the journals for holding the journals apart and it has an axial length that is greater than the axial width of the roller so that the roller rotates freely between the journals.
