Keyway Wheels / Drive Wheels · 4" to 10" · 450 to 2,250 lb · Polyurethane

These keyed polyurethane drive wheels replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 450 to 2,250 lb per wheel. Wheels in this category range 4 x 1-1/2 to 10 x 3 in this collection. Capacities below are per wheel unless a listing says set. Polyurethane bonded to a steel hub is quiet, protects floors, and carries heavy loads with low rolling effort. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Common uses include drive units, tow lines, industrial carts, and plant equipment. Match the bore, hub length, diameter, and tread width before you order. Order the axle and spacers if the old ones are worn. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Wheel aisle: polyurethane wheels. Wheel hub: replacement wheels.

Choosing keyway drive wheels

Load: divide the loaded weight by three for a four-wheel cart [S2]. A 1,500 lb wheel from this page then suits about 4,500 lb, and the strongest at 2,250 lb about 6,750 lb.
Floor: on keyway drive wheels, polyurethane protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
