Discover why this heavy duty caster is the best choice for your toughest tasks.

Superior Load Capacity and Longevity from a Kingpinless Caster

The Model 50 heavy duty industrial caster is built for heavier loads and arduous service, thanks to its robust design. Equipped with a 3-inch wide PX Premium Polyurethane on Iron wheel (available in 6-inch, 8-inch, 10-inch, and 12-inch diameters), each wheel can support up to 6,500 lbs.  The PX wheel’s special polyurethane formula reduces heat buildup, extending lifespan and maintaining performance under continuous high-stress conditions, outperforming standard polyurethane wheels. This makes it ideal for heavy duty casters in automotive tow-lines, warehouse logistics, or aerospace component transport, where reliability and reduced maintenance are critical.

The precision-machined swivel bearing in the Model 50 industrial caster enables smooth swiveling, minimizes vibration, and provides long-lasting performance, even under heavy loads. Its 5 1/4″ x 7 1/4″ top plate, with 3 3/8″ x 5 1/4″ bolt hole spacing (slotted to 4 1/8″ x 6 1/8″) and 1/2″ mounting bolts, offers a secure foundation for heavy duty industrial casters. Zinc-plated frames and grease fittings for all moving parts ensure rust resistance and low upkeep, making this caster a dependable choice for rugged environments like manufacturing plants or distribution centers.

Floor Protection and Quiet Performance

Protecting floors while moving heavy loads is a key challenge in industrial settings, and the PX Premium Polyurethane on Iron Wheel rises to the occasion. Its non-marking, impact-absorbing tread safeguards smooth surfaces in factories, hangars, and warehouses, unlike metal wheels that can scratch or damage floors. The orange polyurethane tread moves effortlessly over debris with low rolling resistance, reducing the effort needed to haul heavy equipment. This makes the Model 50 heavy duty caster perfect for industrial casters in high-traffic areas where floor care is essential, such as aerospace assembly or automotive plants.

The 95A durometer tread also cuts down noise and vibration, creating a quieter workspace—crucial for precision assembly lines or busy distribution centers. Whether powering carts, conveyors, or mobile helipads, the PX wheel’s floor-protecting design preserves surfaces and cargo, while its chemical resistance to oils, grease, and harsh substances ensures durability in tough conditions. These heavy duty industrial casters are not suited for rough terrain or sudden shocks but perform best on smooth surfaces.

With precision sealed ball bearings or optional tapered roller bearings, the Model 50 industrial caster operates reliably from -20°F to 180°F. Its 3/8-inch thick legs and 1-inch axle enhance stability, while options like face contact wheel brakes or hand-operated swivel locks allow customization for secure locking or straight-line travel.

Why Choose the Model 50 with PX Wheels?

The Model 50 heavy-duty industrial caster with PX Premium Polyurethane on Iron Wheels is the premier choice for heavy duty casters, offering a perfect blend of strength, floor protection, and smooth operation. Its larger top plate, thicker legs, and precision swivel bearing tackle heavier loads and tougher conditions than standard casters, while the PX wheel’s heat-resistant, non-marking tread, capable of supporting 6,500 lbs per wheel, delivers lasting performance and surface safety. Whether in aerospace, automotive, or warehousing, this industrial caster powers your operations with reliability and efficiency.

Customize with brakes or swivel locks to meet your specific needs. Trust Caster City for heavy duty industrial casters that conquer your toughest challenges.

Polyurethane on Iron Model 50 Swivel Casters with Heavy Duty utilize the same caster wheels shown in the model 30 plate caster.  However, plate caster model 50 has a larger mounting plate, thicker mounting plate, and thicker legs.  This allows for heavier loads and more arduous service.  The precision machined swivel provides unmatched} performance on both manually moved and mechanically powered machinery. Popular options customers like to include is a face contact wheel brake to latch the wheels and a hand operated swivel latch that converts the swivel caster into a rigid caster for direct line travel. There are lubrication fittings for all adjustable parts, and the metal frames are zinc plated for rust resistance.

Premium Polyurethane (PX) Industrial Caster Wheel

The PX Industrial Caster Wheel from Caster City is our highest-capacity polyurethane caster wheel, engineered for heavy-duty applications. Built with a premium 95A Durometer polyurethane tread (available in ½”, ¾”, or 1” thickness depending on width) and finished in signature orange, this wheel is softer and more resilient than standard 65D polyurethane or other heavy industrial options. It delivers unmatched performance for power towing and transporting large loads indoors or outdoors.

Key Features and Benefits

• Superior Load Capacity and Durability: Supports higher loads than any other polyurethane caster wheel we manufacture, thanks to our proprietary Megapoly™ compound. This advanced formulation slows internal heat buildup from extreme loads, extending wheel lifespan and ensuring reliable performance under the heaviest demands.
• Enhanced Resiliency and Ease of Motion: The soft, rebounding polyurethane tread requires less effort to initiate movement, making it ideal for one-person operation of substantial cargo. Its rapid rebound action outperforms standard polyurethane or rubber wheels, making it easier to start and maintain motion in manufacturing, staging, or facility transitions.
• Smoother Ride and Protection: Provides a vibration-dampening ride that safeguards sensitive machinery, components, and cargo. The thick tread also protects floors from wear, chipping, and “jackhammer” impacts common with harder wheels.
• Bearing Options: Available with either precision sealed ball bearings or tapered roller bearings for maximum rolling efficiency, especially during towing.

This caster wheel excels in industrial environments, balancing extreme capacity with floor-friendly resilience for seamless heavy-load handling. Contact us at Caster City today for custom configurations.

What is Durometer and How is it Measured?
Durometer measures polyurethane hardness on the Shore scale.

• Shore A (softer treads): 75A for RF wheel, 65A for RH wheel, 60A for RQ wheel, 50A for RS wheel,
  95A for the PX Polyurethane wheel
• Shore D (harder treads): 70D for PYH or HU Polyurethane Wheels
