4″ Crown Orange Polyurethane on Aluminum
The UAO Crown Tread Polyurethane on Aluminum Hub Wheel, now upgraded with high-efficiency, maintenance-free SPS stainless steel precision sealed ball bearings, is a non-marking industrial wheel for heavy duty casters. Featuring a crown tread, high quality polyurethane tire with a 90 Shore A durometer hardness, chemically and mechanically bonded to a durable aluminum hub, available in orange. This industrial caster supports heavy loads up to 1,000 lbs per wheel. Designed to efficiently change directions, it offers higher capacity and more floor protection than hard composition wheels or metal wheels, rolling easier than conventional rubber caster wheels on smooth floors. Available in 4”, 5”, 6”, and 8” diameters, this industrial caster wheel uses a large crown tread and counter bored hub to minimize surface friction, requiring less effort to start up, turn, and maintain a rolling load, operating within a temperature range of -40°F to 180°F, ideal for dry factory floors where its lighter weight and aesthetic appeal outshine polyurethane on iron wheels. Contact Caster City with any questions about how to use this wheel.
This aluminum caster wheel in heavy duty industrial casters balances durability and performance, protecting floors better than metal wheels while withstanding impacts and heavy loads. The SPS stainless steel precision sealed ball bearings enhance corrosion resistance, making it suitable for environments like food processing or pharmaceutical labs, though it’s not suited for shock, overloading, abuse, or prolonged standing loads. The bonding agent holding the polyurethane tire to the aluminum center can be affected by exposure to some chemicals, impact, overloading, or heat buildup from continuous usage, so chemical compatibility should be verified. The UAO wheel ensures minimal vibration and prolonged equipment life, making it a top pick for material handling carts, warehouse equipment, and manually operated setups needing a semi-cushioned, low-effort rolling experience with an attractive appearance.
Equipped with SPS stainless steel bearings, the UAO wheel excels in hygiene-critical settings like bakeries, dairies, or cleanrooms, where its non-marking tread and corrosion-resistant bearings deliver reliable performance. Its smooth, quiet operation supports seamless mobility in hospitals, schools, or hotels, while the robust aluminum hub withstands demanding industrial applications. This heavy duty industrial caster wheel is a reliable choice for diverse setups requiring both functionality and visual appeal, ensuring long-lasting, maintenance-free reliability.
Note: Certain chemicals may react with the aluminum hub, potentially causing bonding failure—contact Caster City for compatibility details.

FAQ
UAO Crown Tread Polyurethane on Aluminum Hub Wheel with SPS Stainless Steel Precision Sealed Ball Bearings
What makes the UAO wheel with SPS stainless steel precision sealed ball bearings suitable for heavy duty industrial caster applications?
The UAO wheel, available in 4”, 5”, 6”, and 8” diameters, features a 90 Shore A polyurethane tread chemically bonded to an aluminum hub, supporting up to 1,000 lbs per wheel, perfect for heavy duty industrial caster needs. Its high-efficiency, maintenance-free SPS stainless steel precision sealed ball bearings ensure a quiet, smooth ride in food processing plants, hospitals, and pharmaceutical labs. The hard crown tread minimizes surface friction, protects floors from scuffs, and rolls easier than rubber caster wheels, while the non-rusting aluminum hub enhances durability in high-moisture settings. Note: Certain chemicals may react with the aluminum hub, potentially causing bonding failure—contact us for compatibility details.
Can the UAO wheel in all sizes be used as a swivel plate caster in corrosive industrial environments?
Yes, the UAO wheel in 4”, 5”, 6”, and 8” sizes is ideal for swivel plate caster setups in corrosive environments like chemical plants or marine facilities. Its polyurethane tread and high-efficiency, maintenance-free SPS stainless steel precision sealed ball bearings deliver low-resistance, non-marking performance, supporting up to 1,000 lbs per wheel. The aluminum hub and crown tread design ensure easy turning and floor protection, making it a top choice for heavy duty industrial caster applications in demanding settings.
Is the UAO wheel with SPS stainless steel bearings a good fit for stainless steel industrial wheel applications in food processing?
Absolutely, the UAO wheel in 4”, 5”, 6”, and 8” sizes shines as a stainless steel industrial wheel for food processing environments like bakeries or dairies. Its 90 Shore A polyurethane tread, bonded to a non-rusting aluminum hub, resists wear in high-moisture settings, while the SPS stainless steel precision sealed ball bearings ensure quiet, smooth operation. Supporting up to 1,000 lbs per wheel, it protects floors and performs reliably for heavy duty casters and wheels in hygiene-critical applications.
How does the UAO wheel in all sizes perform as an industrial caster in pharmaceutical or cleanroom environments?
The UAO wheel, available in 4”, 5”, 6”, and 8” sizes, is an excellent industrial caster for pharmaceutical manufacturing and cleanrooms. Its non-marking polyurethane tread rejects debris, maintaining cleanliness, while high-efficiency, maintenance-free SPS stainless steel precision sealed ball bearings provide low-effort, quiet mobility, supporting up to 1,000 lbs per wheel. The aluminum hub and crown tread ensure durability and floor protection, ideal for heavy duty industrial caster applications in sensitive settings.
Can the UAO wheel with SPS stainless steel bearings handle outdoor use as a heavy duty caster in marine or coastal environments?
Yes, the UAO wheel in 4”, 5”, 6”, and 8” sizes is suited for outdoor heavy duty caster applications in marine or coastal settings like shipyards or ports. Its polyurethane tread and non-rusting aluminum hub resist wear in humid, salty conditions, while high-efficiency, maintenance-free SPS stainless steel precision sealed ball bearings ensure smooth performance, supporting up to 1,000 lbs per wheel. The crown tread protects surfaces, though chemical compatibility should be verified.
