Colson Caster Corp. announced the availability of a new wheel bearing for use in quiet and clean environments. The new Hand Truck Bearing is designed to integrate easily with Colson’s own Performa Hand Truck wheel selection. Because they are completely sealed to keep grease in and debris out there is no maintenance or lubrication required, the company says. Replacing Colson’s original styled Radial Ball Bearing for Hand Trucks, the new bearing is sized at 5/8-inch ID by 1 and 3/8-inch OD and an additional version of the bearing at ¾-inch ID by 1 and 3/8 inch OD.
