Model 30 Heavy Duty Kingpinless Swivel Casters

The Model 30 Heavy Duty Kingpinless Swivel Casters outperform the Model G15 series with a larger 3-inch diameter swivel bearing under the mounting plate and 2.50-inch and 3-inch wide wheels. This hot-forged, precision-machined swivel caster ensures reliable performance for manually operated and mechanically powered equipment. The frames, made from ASTM1045 zinc-plated steel, resist rust for durability in tough environments. Lubrication fittings equip all moving parts for smooth operation, and the ¾-inch axle diameter supports robust functionality. With a maximum capacity of up to 7,000 lbs per caster, depending on the wheel, the Model 30 excels in heavy-duty industrial applications requiring strength and precision.

DS – Ductile Steel Wheel for Model 30 Plate Caster

The DS – Ductile Steel Wheel is designed for extreme load capacities in demanding industrial settings, such as steel mills, power plants, or automotive facilities. Available in sizes with a wheel width of 2.5 inches and 3 inches and wheel diameters of 6 inches, 8 inches, 10 inches, and 12 inches, it supports up to 6,000 lbs per wheel with roller bearings and over 7,000 lbs with tapered roller bearings.  Made from ductile steel, this flat tread wheel offers a 45,000 PSI tensile strength, ensuring superior durability compared to cast iron while being more cost-effective than drop-forged steel. It operates effectively in temperatures from -45°F to 800°F, making it ideal for harsh environments like chemical plants or mining operations. The DS – Ductile Steel Wheel’s flat tread design and high tensile strength deliver dependable performance in demanding applications, including:

• Mining ore carts, transporting heavy loads over rough surfaces.
• Powder coating large metal structures, supporting heavy components during finishing processes.
• Welding tables, providing stable mobility for heavy-duty fabrication.
• Heavy manufacturing, moving oversized machinery or parts.
• Oversized gear handling, ensuring smooth transport in precision engineering.
• Steel mills, managing molten metal loads under extreme conditions.
• Construction on rough terrain, navigating uneven surfaces with heavy equipment.
• High-heat industrial oven racks, withstanding elevated temperatures.
• Tractor stands, supporting heavy agricultural equipment during maintenance or storage.

Its durable construction ensures a long service life, with options for roller or tapered roller bearings to maintain smooth operation in rugged conditions. Due to the wheel’s hardness, it may cause marking or damage to factory floors, especially in applications where loads exceed the capacity of floor-protective wheels or where severe service conditions exist. In such cases, users often prioritize the wheel’s performance over floor wear, as the work performed outweighs the cost of potential floor damage. For sensitive surfaces, steel plates or V-groove tracks are recommended to minimize damage. Paired with the Model 30’s zinc-plated steel frame and kingpinless design, this caster is a top choice for heavy-duty plate caster applications requiring exceptional strength and performance in dry or wet conditions, such as oil rigs, logistics hubs, observatories, or agricultural settings with tractor stands. Optional add-ons include a face contact wheel brake and a swivel latch for applications requiring a rigid caster configuration. These features enhance versatility, allowing the caster to adapt to specific operational needs, such as securing heavy loads during stationary tasks or ensuring controlled movement in dynamic environments.

Application Uses

The Model 30 Heavy Duty Kingpinless Swivel Casters excel in environments where extreme durability and high load capacities are critical. In steel mills, they handle molten metal loads, enduring high temperatures and heavy weights. Power plants rely on these casters to move large equipment components across uneven surfaces. Automotive facilities use them to transport heavy parts during assembly or maintenance. In mining operations, the casters support ore carts navigating rough terrain. Chemical plants benefit from their ability to withstand harsh conditions, while construction sites use them for equipment on uneven ground. Logistics hubs employ these casters for efficient movement of oversized loads, and observatories utilize them for precise positioning of heavy equipment. In agricultural settings, tractor stands leverage the casters’ strength to support heavy machinery during maintenance or storage, ensuring stability and mobility. The ductile steel wheel’s hardness makes it ideal for applications where floor protection is secondary to performance. For example, in heavy manufacturing, the casters support oversized gear or machinery, where floor wear is acceptable given the workload. Similarly, in powder coating or welding applications, the casters’ ability to handle heavy structures outweighs concerns about floor damage. In high-heat environments, such as industrial ovens, the wheels maintain integrity at temperatures up to 800°F, ensuring reliable operation. For users prioritizing floor protection, steel plates or V-groove tracks provide a practical solution to minimize marking or damage.

Why Choose Model 30?

The Model 30’s kingpinless design eliminates the risk of kingpin failure, a common issue in traditional casters under heavy loads. The 3-inch swivel bearing enhances maneuverability, allowing precise control in tight spaces or high-load scenarios. The zinc-plated steel frame ensures long-term durability by resisting corrosion in wet or chemically aggressive environments, such as oil rigs or chemical plants. Lubrication fittings simplify maintenance, extending the caster’s service life even in severe conditions. The combination of ductile steel wheels and a robust frame makes this caster a cost-effective alternative to drop-forged steel options, offering comparable strength at a lower price point.  Heavy Duty Casters like this with 2.5″ wide wheels are commonly rolling into a track or channel system. The optional face contact wheel brake adds safety by locking the caster in place, while the swivel latch allows conversion to a rigid configuration for straight-line movement, ideal for long-distance transport in logistics or construction.

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.
