Polyurethane Wheel for Electric Lift Trucks

Frequently Asked Questions

Q: What are the material specifications for the 220007920 wheel?
A: The 220007920 features high-resilience, abrasion-resistant polyurethane tread bonded to a QT450 cast iron center. The wheel includes a press-fit steel ring with cast iron (QT450 x 10) or carbon steel (GB/T-20) specification, engineered for structural integrity under heavy loads.

Q: What equipment types use the 220007920 wheel?
A: The 220007920 is designed for electric lift truck applications, including electric pallet jacks, stackers, and warehouse material handling equipment from major manufacturers such as Nichiyu, Toyota, Crown, Hyster, Yale, and Raymond.

Q: What are the performance advantages of this polyurethane wheel?
A: This wheel delivers minimal rolling resistance, superior abrasion resistance, and enhanced durability in low-temperature and heavy-duty service environments. The polyurethane tread provides excellent traction and floor protection while the QT450 cast iron center ensures structural durability under intensive use.

Q: How should I inspect the 220007920 wheel for wear?
A: Regularly inspect the wheel for flat spots, tread separation, uneven wear patterns, or loss of tread adhesion to the center. Clean debris and buildup from the wheel surface. Monitor for increased rolling drag, which may indicate bearing wear or wheel damage requiring replacement.

Q: When should the 220007920 wheel be replaced?
A: Replace the wheel when visible tread damage, flat spots, structural defects, or permanent separation of the polyurethane tread from the cast iron center occurs. Wheel lifespan varies based on load capacity, floor conditions, and frequency of use in warehouse operations.

Q: How should polyurethane wheels be stored?
A: Store wheels in a cool, dry environment away from direct sunlight to prevent polyurethane deterioration. Avoid stacking heavy items on wheels, and protect from extreme temperature fluctuations that may affect polyurethane material integrity.

Q: Is the 220007920 compatible with my specific lift truck model?
A: Verify wheel dimensions, bore size, and mounting specifications match your equipment before ordering. Consult your lift truck manual or contact the manufacturer to confirm compatibility with your specific model.

Q: What are the material properties and temperature range for this polyurethane wheel?
A: The wheel is constructed with high-resilience polyurethane tread optimized for low-temperature and heavy-duty service environments. The polyurethane material provides superior abrasion resistance and durability in demanding warehouse and cold storage applications. The QT450 cast iron center ensures structural integrity under heavy loads.

Q: How long does the 220007920 wheel typically last in warehouse service?
A: Polyurethane wheel lifespan depends on load capacity, floor conditions, and frequency of use. The abrasion-resistant polyurethane tread and cast iron center are engineered for extended durability in intensive material handling operations. Worn or damaged treads, loss of adhesion, or flat spots indicate the wheel requires replacement.

Q: What maintenance is required for the 220007920 wheel?
A: Inspect wheels regularly for wear, flat spots, or separation of the tread from the center. Clean debris and buildup from the wheel surface to maintain traction. Monitor rolling resistance; increased drag may indicate bearing wear rather than wheel wear. Replace wheels when tread damage, uneven wear, or structural defects appear.
