 Ball transfer units are simple, but very convenient and practical units, which substitute sliding friction for rolling friction in the systems where it is necessary to move cargos along the horizontal surface in any direction.Transfer units are made as undetachable units, composed of a steel or plastic ball; of machined, cast or pressed housing with a cavity in the form of a hemisphere; of a set of balls, filling the clearance between the ball and the surface of the housing cavity; and of a cover with the hole having built-in seal. Transfer units can have built-in damping spring or device to adjust the height of support, as well as various mounting tools. Ball transfer units are perfect for using in production and assembly lines, work feeders of metal-working machines, warehouse terminals and conveyor platforms.
