Description Model 30 Rigid Caster is a step up from the rigid casters shown on Model G15. These Rigid casters have wider wheels, large wheel bearings, a higher load capacity rating, and a bigger mounting plate than the rigid caster that is shown on G15. It features superior performance on both manually moved and mechanically powered equipment. The Model 30 frames are zinc plated for rust resistance. There are lubrication fittings for the wheel bearings. Rigid casters are usually attached to equipment at the opposite end of the push handle and where swivel casters are attached. This enables the person pushing the equipment to be able to control the direction of travel. It should also be noted that Rigid casters have 2 legs perpendicular to the mount plate, therefore they can not move sideways. 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 information and help placing an order, give us a call at 800-501-3808. The DSC Ductile Steel industrial caster wheel features a slight crown on the tread, unlike the flat tread on the standard DS wheel. When your application calls for severe conditions and is too heavy for floor protective wheels, the DSC Ductile steel industrial caster wheel will do the job. The crowned tread greatly reduces the force needed to change directions from a stopped position. Ductile steel wheels are selected due to their ductility and tensile strength, which allows them to absorb shocks and impacts without failure. These solid steel wheels are incredibly durable in normal service and ensure reliable performance in rugged environments. Caster City manufactures all of our steel wheels with a lubrication fitting in the hub. We offer DSC Ductile steel industrial caster wheels with roller bearings or sealed precision ball bearings, with load ratings determined solely by bearing capacity. Ductile steel wheels like this can withstand high temperatures up to 400°F depending upon the application. Ductile steel industrial caster wheels are destructive to most factory floors and are typically used while on steel plating to protect manufacturing facilities from floor damage. Ideal for blast furnace operations, heavy fabrication shops, die and mold transport, and automotive assembly.
