8 x 3″ Ductile Steel Slight Crown – Model 30 Rigid Caster

Description

Model 30 is an upgrade 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 grease fittings for the wheel bearings. Rigid casters are usually attached to machinery 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 stressed 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 handled into position. For more information and/or help placing an order, please give us a call at 800-501-3808.

The DSC – Ductile Steel Wheel with Slight Crown for the Plate Caster Model 30 is a heavy duty industrial caster wheel designed to handle extreme load capacities in the toughest industrial settings like steel mills power plants or automotive plants with all sizes 6” x 3” 8” x 3” 10” x 3” and 12” x 3” supporting 6000 lbs per wheel with roller bearings and over 7000 lbs with tapered roller bearings though the bracket limits it to 7000 lbs per caster. Made from ductile steel a combination of special alloys often called malleable iron this slight crown tread wheel boasts a 45000 PSI tensile strength shrugging off wear and tear with higher weight capacities than cast iron and being more economical than drop-forged steel. It can handle temperatures from -45°F to 800°F making it great for harsh environments in industries like chemical plants or mining operations.

The DSC – Ductile Steel Wheel with Slight Crown’s slight crown tread design allows it to swivel in place much easier than a flat-tread steel wheel due to the point-contact nature of the tread surface making it ideal for applications needing frequent directional changes like mining hauling ore carts powder coating big metal structures welding tables heavy parts heavy manufacturing oversized gear steel mills molten metal loads construction rough terrain and industrial ovens high-heat racks. Its durability ensures a long life with options for roller bearings or tapered roller bearings for smooth rolling in the roughest settings though the point-contact nature can be more damaging to factory floors than flat-tread wheels so use steel plates or V-groove tracks for sensitive floors. Paired with the Model 30’s zinc-plated steel frame this heavy duty kingpinless caster is a top choice among industrial casters and wheels for heavy duty plate caster applications needing unmatched strength easier swiveling and performance in dry or wet conditions like oil rigs logistics hubs or observatories.

Ductile Steel Caster Wheels from Caster City

Caster City’s Ductile Steel Industrial Caster Wheels are designed for heavy-duty applications where loads surpass the capacity of floor-protective wheels or severe service conditions are present. Ideal for industrial and manufacturing settings where floor wear is secondary to the critical tasks performed, these wheels are available in 2”, 3”, and 4” widths and diameters ranging from 4” to 16”. With high ductility and tensile strength, our ductile steel wheels absorb shocks and impacts without failure, ensuring reliable performance in rugged environments. For precise, guided movement, we offer a V-groove design that rolls smoothly on inverted angle iron tracks, providing stable and controlled operation in demanding conditions.

These Ductile Steel Industrial Caster Wheels are built for exceptional durability, featuring either roller bearings or sealed precision ball bearings, with load ratings determined solely by bearing capacity. Each wheel includes a lubrication fitting in the hub for easy maintenance and prolonged service life. Capable of withstanding temperatures up to 400°F depending on the application, these solid steel wheels are well-suited for challenging environments. For continuous temperatures above 400°F, where steel roller bearings and spanner bushings may anneal, consult our engineering team to ensure optimal performance in high-temperature applications.

While Ductile Steel Industrial Caster Wheels excel at handling substantial loads in harsh conditions, they can damage most factory floors under heavy loads. To mitigate this, they are typically used on steel plating, in metal channels, or as V-grooved wheels on angle iron tracks to protect costly flooring. Compared to Gray Iron wheels, our ductile steel wheels offer superior ductility and tensile strength, making them the top choice for environments requiring shock absorption and reliability. Contact Caster City for custom configurations to meet your heavy-duty needs with our durable, high-capacity ductile steel wheels.
