Ball roller hardened submerged pressed Swede-wheel

Ball roller for submerged press fitting with a larger steel ball immersed in a bed of smaller steel balls. All parts are hardened for greater load capacity and longer life. The ball housing is made of galvanized pressed sheet metal, and is self-cleaning via cleanout holes in the bottom. Used on workstations for horizontal manual movement of packages/goods with hard and flat bottom. Placed so that at least three balls in each direction are always in contact with the goods.
