Heavy Duty Twin Wheel Castors are manufactured by N. C. Enterprises. N. C. Enterprises is an ISO 9001:2000 certified company that offers standard and specialized light-duty castor, medium-duty castor, heavy-duty castor and extra heavy-duty castor and wheels. This range of Heavy Duty Twin Wheel Castors is the most comprehensive of its style. The swivel has a heavy duty forged steel top plate which joins the outer swivel ring by a full complement ball race [Rexello unique side race]. The race serves both as thrust and radial bearing and is provided with a Nylon seal at the top and greased through a hydraulic nipple. This construction prevents downward escape of the lubricant and creates a complete grease reservoir. The press formed heavy duty cylindrical shaped side plates are continuously welded to the swivel ring to form the fork and give the best strength to weight ratio.
