What Are PU Wheels?
PU wheels are wheels coated or molded with polyurethane, a high-performance elastomer that combines the durability of rubber with the load-bearing strength of metal. Widely used in industrial, logistics, and automation applications, PU wheels offer an ideal balance of wear resistance, noise reduction, and floor protection.
At Xibeiyou, we manufacture a full range of polyurethane wheels — including PU coated wheels, caster wheels, conveyor drive wheels, load rollers, and idler wheels — engineered for demanding environments across manufacturing, warehousing, and heavy machinery.
Key Properties of Polyurethane Wheels
Polyurethane is chosen over traditional rubber, nylon, or steel wheels for several reasons:
- High Load Capacity — PU wheels can support significantly heavier loads than rubber wheels of the same size, making them suitable for heavy-duty industrial applications.
- Excellent Wear Resistance — Polyurethane has a longer service life than most elastomers, reducing replacement frequency and maintenance costs.
- Floor-Friendly — PU wheels are non-marking and gentle on concrete, epoxy, and tile floors, which is critical in clean-room and warehouse environments.
- Noise Reduction — Compared to metal wheels, PU wheels operate quietly, improving workplace comfort.
- Chemical & Oil Resistance — Polyurethane resists degradation from oils, greases, and many industrial chemicals.
- Customizable Hardness — PU wheels can be manufactured in a wide range of Shore hardness levels (from soft 60A to hard 95A), allowing precise tuning for specific applications.
Common Applications
PU wheels are used across a wide spectrum of industries:
- AGV & Automated Guided Vehicles — Drive wheels, steering wheels, and load wheels for autonomous mobile robots
- Warehouse Logistics — Caster wheels for carts, trolleys, and material handling equipment
- Conveyor Systems — Drive rollers, idler rollers, and friction wheels for belt and roller conveyors
- Stacker Cranes & Shuttle Cars — High-precision wheels for automated storage and retrieval systems
- Heavy Machinery — Wheels for mining equipment, TBM (tunnel boring machines), and construction vehicles
- Automotive Production Lines — Transfer and positioning wheels on assembly lines
- Amusement Rides & Textile Equipment — Specialized PU rollers for unique operational requirements
How to Choose the Right PU Wheel
Selecting the correct polyurethane wheel depends on several factors:
- Load Requirement — Determine the maximum static and dynamic load per wheel. Heavier loads require higher Shore hardness and larger wheel diameters.
- Operating Speed — High-speed applications may need precision-balanced wheels with low rolling resistance.
- Floor Conditions — Smooth indoor floors benefit from softer PU compounds, while rough or outdoor surfaces may require harder formulations.
- Temperature Range — Standard PU wheels perform well from -20°C to +80°C. For extreme environments, specialized compounds like Vulkollan may be necessary.
- Wheel Size & Bore — Match the wheel diameter, width, and bore size to your existing equipment specifications.
- Custom Requirements — OEM projects may require specific hub materials, bearing types, or surface profiles.
