9UDC6x2-S (Swivel Caster) – The Ultimate Carpet Caster
The UDC crown tread polyurethane wheel uses 65D Shore D hardness (2.5-3× stiffer than standard 95A polyurethane) to fundamentally change how wheels interact with carpet. While conventional flat tread wheels compress into carpet pile, creating a plowing wave of buckled fibers, the UDC’s hard crown acts as a wedge that parts fibers laterally rather than crushing them vertically. The crowned geometry concentrates each wheel’s load into a 0.4-0.6″ contact patch, exceeding the fiber buckling threshold and forcing carpet fibers to deflect around the wheel rather than compress beneath it. This dramatically reduces rolling resistance and cuts swivel resistance by up to 80% compared to 95A flat tread polyurethane wheels. The minimal tire deflection of hard polyurethane means up to 60% less energy lost per revolution per wheel compared to softer flat polyurethane, enabling sustained operation on carpet without thermal bond degradation. Fibers spring back immediately after the crown passes, eliminating the viscoelastic lag and fiber bunching that plague soft rubber and standard Shore A polyurethane wheels.
Comparative analysis: A 6×2 wheel with 95A flat tread polyurethane maintains a contact patch up to 4× larger than the “UDC” crown tread polyurethane wheel. The result is vertical compression, buckling, and a continuous resistance wave ahead of each flat wheel. The 65D crown tread engages far fewer carpet fibers per wheel across its narrow tread face, forcing lateral deflection instead of vertical crushing. The crown’s reduced moment arm cuts swivel friction dramatically, allowing operators to change direction with significantly less effort. Service life extends through superior abrasion resistance inherent to hard durometer polyurethane, and the narrow contact patch experiences one-fifth the wear rate of full-width flat treads. Ideal for hospital equipment carts, hotel housekeeping, office furniture, and conference room AV systems transporting 1,200-1,600 lb loads where carpet dominates but hard floor transitions occur. The UDC 6×2 crown tread delivers reduced push force in real-world conditions. Wheel comes equipped with maintenance-free precision sealed ball bearings to further reduce the effort required for staff to move 1,400 lb loads on carpeted surfaces.
The Model 9 swivel bearing uses flame-hardened raceways with dual rows of balls and a 5/8″ welded kingpin, providing smooth 360-degree rotation under the full 1,000 lb load rating. The 4×4-1/2″ zinc-plated steel mounting plate with 2-5/8×3-5/8″ bolt pattern makes installation straightforward on most equipment. This swivel caster thrives in dry indoor factories, assembly lines, hospitals, and anywhere operators need a low-effort, maneuverable solution that protects floors while handling serious weight. The maintenance-free sealed bearings and non-marking blue tread make it ideal for clean environments where downtime isn’t an option and appearance matters.
DO NOT ORDER SWIVEL LOCK OR RACEWAY SEALS IF YOU ORDER THE TL – TOTAL LOCK BRAKE. THE TL BRAKE WILL NOT WORK WITH EITHER THE SWIVEL LOCK OR RACEWAY SEALS.

FAQ
What makes the UDC Crown Tread Polyurethane on Aluminum Hub Wheel a good industrial wheel for heavy duty casters?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel offers the lowest rolling resistance of any polyurethane wheel, with a 65D durometer hard crown tread that cuts through carpet fibers and changes directions effortlessly while supporting heavy loads up to 1,200 lbs, making it ideal for heavy duty Model 9 casters.
What materials are used in the UDC Crown Tread Polyurethane on Aluminum Hub Wheel for casters and wheels?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel features a non-marking high quality polyurethane tire with a 65 Shore D durometer, chemically and mechanically bonded to a lightweight aluminum hub, available in blue only.
What applications are best suited for the UDC Crown Tread Polyurethane on Aluminum Hub Wheel as a heavy duty wheel?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel excels on parade floats, carpeted staging areas, medical equipment, warehouse carts, and material handling setups on smooth floors or indoor carpet, where Model 9 heavy duty casters need maximum ergonomics and minimal rolling effort.
How does the UDC Crown Tread Polyurethane on Aluminum Hub Wheel handle carpet as an industrial caster wheel?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel cuts through carpet pile like a wedge instead of compressing fibers, with its 65D hard crown creating a line contact that parts fibers cleanly, eliminating the bunching and drag common with soft rubber wheels on Model 9 heavy duty casters.
Why does the UDC Crown Tread Polyurethane on Aluminum Hub Wheel reduce rolling effort for heavy duty casters?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel’s large crown tread and counter-bored hub with precision sealed ball bearings minimize surface friction and deflection, requiring less effort to start, turn, and maintain rolling loads than any other polyurethane wheel on Model 9 casters.
Why use the UDC Crown Tread Polyurethane on Aluminum Hub Wheel for heavy duty casters instead of softer wheels?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel delivers maximum ergonomics with its 65D durometer that eliminates tire deflection and carpet fiber compression, reducing draw bar pull significantly compared to softer wheels, making it the top choice for long-distance manual movement on Model 9 heavy duty casters.
What bearing type comes with the UDC Crown Tread Polyurethane on Aluminum Hub Wheel for heavy duty casters?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel comes with a counter-bored hub using precision sealed ball bearings, maintenance-free and designed for smooth operation in industrial caster wheel applications on Model 9 frames.
What’s the temperature range for the UDC Crown Tread Polyurethane on Aluminum Hub Wheel in industrial casters?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel operates from -40°F to 180°F with its 65 Shore D durometer, making it suitable for Model 9 heavy duty casters in typical indoor and outdoor environments, though caustic chemical exposure should be avoided due to aluminum hub reactivity.
What sizes and load capacities does the UDC Crown Tread Polyurethane on Aluminum Hub Wheel offer for casters and wheels?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel is available in 6×2 and 8×2 sizes only, supporting 1,000 lbs (6×2) and 1,200 lbs (8×2) per wheel for Model 9 industrial caster applications requiring the lowest rolling resistance and maximum maneuverability.
Why is the UDC Crown Tread Polyurethane on Aluminum Hub Wheel a top choice for heavy duty industrial usage with manual equipment?
The UDC Crown Tread Polyurethane on Aluminum Hub Wheel is the top choice for heavy duty industrial usage with its non-marking blue tread, lightweight aluminum hub for reduced push force, superior heat dissipation, and attractive appearance, delivering the lowest rolling resistance available on Model 9 casters for parade floats, medical carts, and carpeted environments up to 1,200 lbs.
