Description
10″ x 4″ Premium Polyurethane Tire with Iron Center Shown in photo with 10 x 3″.
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
Premium Polyurethane (PX) Industrial Caster Wheel from Caster City

The Premium Polyurethane Wheel is our highest-capacity polyurethane wheel, designed for heavy-duty applications. Crafted with a signature orange, 95A Durometer polyurethane tread, available in ½”, ¾”, or 1” thickness depending on width, this wheel is softer and more resilient than standard 65D polyurethane or other heavy industrial alternatives. Its proprietary Megapoly™ compound slows internal heat buildup from extreme loads, significantly increasing load capacity and lifespan. This makes the PX wheel ideal for power towing and transporting large loads indoors or outdoors, offering unmatched durability and performance in demanding industrial environments.
The PX wheel’s resilient 95A Durometer tread provides exceptional ease of motion, requiring less effort to initiate movement, perfect for one-person operation of substantial cargo. Its rapid rebound spring action outperforms standard polyurethane or rubber wheels, making it easier to start and maintain motion in manufacturing, staging, or facility transitions. Equipped with either precision sealed ball bearings or tapered roller bearings, the PX ensures optimal rolling efficiency, especially during towing. The 1” thick tread delivers a smoother, vibration-dampening ride, protecting sensitive machinery, components, and costly floors from wear, chipping, or “jackhammer” impacts common with harder wheels.
This industrial caster wheel excels in balancing extreme load capacity with floor-friendly resilience, making it the top choice for seamless heavy-load handling. The PX wheel’s unique resiliency, compared to other polyurethane wheels of its size, enhances towing performance and protects cargo during transport inside and outside facilities.
