Description Model 30 Rigid Caster is a step up from the rigid casters shown on G15 Rigid Caster. These Rigid casters have bigger wheels, huge wheel bearings, a greater weight load rating, and a bigger mounting plate than the rigid caster that is shown on G15. It is designed to provide superior performance on both automated and hand powered equipment. The 30 Rigid Caster frames are zinc plated for prevention against rust. There are lubrication fittings for the wheel bearings. Rigids are usually attached to equipment at the opposite end of the push handle and where swivel casters are attached. This enables the person or employee pushing the equipment to be able to control the direction of travel. It should also be noted that rigids have 2 legs horizontal to the mount plate, stopping any kind of sideways moving. Equipment with 2 rigid casters and 2 swivel casters must be maneuvered into position. 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. This caster is also available in 304 Stainless Steel as the SS-30 for wet or corrosive applications. For more info and help placing an order, contact us at 800-501-3808. 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 premium polyurethane (PX) caster wheel comes with a softer, more resilient polyurethane wheel than standard heavy industrial wheels. The (PX) industrial caster wheel supports more capacity than any other polyurethane caster wheel that we manufacture at Caster City. The 1″ thick tire of this industrial caster wheel makes it ideal for power towing as you transport your largest loads inside and outside of facilities. The industrial caster wheel can come with either sealed precision ball bearings or tapered roller bearings for towing. Ideal for turbine handling, nuclear facility equipment, paper mill machinery, and cement plant operations.
