The precision machined swivel provides unmatched performance on both hand operated and mechanically powered machinery. The metal frames are zinc plated for rust protection, and there are greasing fittings for all adjustable parts. Popular options customers like to include is a face contact wheel brake to latch the wheels and a hand operated swivel latch that converts the swivel caster into a rigid caster for direct line travel. Capacity up to 7,000 pounds per caster. Model 30 features a large swivel and wheel bearing which allows for heavy loads and more arduous service. Benefits include easier swiveling, reduced swivel vibration, and longer trouble free performance. Ideal for automotive assembly lines, heavy machinery moving, and aircraft maintenance stands.

Made from a Megapoly™ polyurethane compound, the PX caster wheel slows down internal heat that builds up from high loads and significantly increases the load capacity and lifespan of the wheel. The (PX) industrial caster wheel is our highest capacity polyurethane industrial wheel and the most resilient polyurethane we offer in a wheel of this size. The PX wheel offers a smoother ride than harder standard polyurethane wheels, protecting sensitive components and machinery from the vibrations of going in and out of a production facility. The tread thickness on this industrial caster wheel is 1″ and makes it an ideal choice for power towing heavy loads. The industrial caster wheel is designed to use either tapered roller bearings or precision sealed ball bearings. Ideal for shipyard operations, oil and gas equipment, and mining operations. *This Plate Caster Model 30 contains Polyurethane on Iron Wheels with Heavy Duty and is displayed with the 10″ x 3″ wheel.  For more information and help placing an order, give us a call at 800-501-3808.
