1. How PU Wheels Work
PU wheels are mounted on the front and rear axles of manual pallet jacks. They facilitate smooth movement across warehouse floors, loading docks, and other indoor surfaces. The polyurethane material provides a balance between hardness and elasticity, allowing the wheels to roll efficiently while protecting floors from damage.
2. Differences Between PU Wheels and Other Materials
-
PU vs. Nylon Wheels: PU wheels are quieter and provide better floor protection, while nylon wheels are more rigid and suitable for rough surfaces.
-
PU vs. Rubber Wheels: PU offers higher load capacity and longer lifespan, whereas rubber wheels provide better shock absorption but wear faster.
-
PU vs. Plastic Wheels: PU is more durable and resistant to oils and chemicals, making it ideal for industrial environments.
3. Applications of PU Wheels
PU wheels are widely used in:
-
Warehouses and logistics centers
-
Manufacturing plants
-
Retail storage environments
-
Food and pharmaceutical industries (due to non-marking and hygienic properties)
-
Environments requiring floor protection and low noise
4. Advantages of PU Wheels
-
High Load Capacity: Suitable for heavy-duty applications.
-
Floor-Friendly: Non-marking and non-scratching.
-
Quiet Operation: Reduces noise in work environments.
-
Durability: Resistant to abrasion, oils, and chemicals.
-
Low Maintenance: Long service life with minimal upkeep.
5. Material Properties
Polyurethane is a polymer material known for its:
-
High tensile strength
-
Elasticity and resilience
-
Resistance to ozone, oxidation, and moisture
-
Ability to maintain performance across a wide temperature range
6. Performance Characteristics
-
Load Rating: Typically ranges from 300 kg to 1,500 kg per wheel.
-
Temperature Range: -30°C to +80°C.
-
Shore Hardness: Usually between 85A and 95A, offering a good balance of hardness and flexibility.
-
Rolling Resistance: Low, ensuring easy maneuvering.
7. Conclusion
Choosing the right PU wheels for your pallet jack depends on factors such as load capacity, floor type, and operational environment. PU wheels offer a reliable, efficient, and protective solution for material handling equipment. With ongoing advancements in material science, PU wheels continue to evolve, providing even better performance and longer service life.
