Description Model 30 Swivel Casters are a step up from swivel caster model G15 in that it features larger swivel, wider wheels, and wheel bearings. The precision machined swivel provides superior performance on both manually moved and mechanically powered machinery. The metal frames are zinc plated for rust resistance, and there are greasing fittings for all moveable parts. Popular options include a face contact wheel brake to lock the wheels and a hand operated swivel lock that converts a 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 shipyard operations, oil and gas equipment, and mining operations. Caster City manufactures this caster and it is also available in 304 Stainless Steel as the SS-30 for wet or corrosive applications.

The PX caster wheel is made from a Megapoly™ polyurethane compound which significantly increases the load capacity and lifespan of the wheel by slowing down internal heat that builds up from high loads. The (PX) industrial caster wheel distinguishes itself from other polyurethane wheels of this size due to its resiliency, which helps when towing cargo inside and outside of buildings, initiating motion through its rebound. The premium polyurethane on iron caster wheel is defined by its 95A Durometer polyurethane, which is softer and more resilient than 65D polyurethane wheels. This industrial caster wheel comes with a 1″ thick orange tire which provides floor protection and a smoother ride as you transition cargo between facilities or when towing it. The industrial caster wheel is designed to use either tapered roller bearings or precision sealed ball bearings. Ideal for forging operations, press and stamping equipment, and industrial oven and furnace carts. *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.
