All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Engineered for OEM, MRO, and defense. Spec-match guarantee, engineering RFQ on every quote, fastest shipping in the caster industry.



This product page covers our 8-inch diameter x 3-inch wide Red Poly on Iron Wheel Casters. Polyurethane on Cast Iron Wheels can withstand a heavy load capacity all while protecting your floors from damage. Easy-rolling, heavy-duty, and affordable. Heavy Duty Casters manufactured with heavy-duty hot forged top plates and yokes using 1045 steel. Deeply grooved double ball bearing raceways with 3/8" Round edge steel legs, double-welded. 3/4" Diameter heat treated kingpin and nut, with a 3/4" axle and lock nut. All casters include a grease fitting in the swivel raceway and are finished off with a zinc-plated finish to increase rust resistance and durability. Power is drawn or manually pushed; the 60 series always delivers. Trusted by some of the biggest names in the fabrication, automotive, and manufacturing industries, these casters will out-perform and over-deliver. These Casters are typically seen on Heavy Duty Carts, Heavy Machinery, Industrial Warehouses, and Food Service Plants.
