Ultra-Poly Steel Wheel

Frequently Asked Questions

Q: What is the TH A8/A9 and what equipment does it fit?
A: The TH A8/A9 is an ultra-poly load wheel designed as a replacement wheel for electric and manual pallet jacks. This is a universal replacement wheel compatible with equipment from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers.

Q: What is the difference between the TH A8/A9 and TH A8/A9-A?
A: The TH A8/A9-A is the detailed specification variant of the TH A8/A9. The TH A8/A9-A features an 95 Shore A polyurethane compound, roller bearings, flat tread profile, and -40°F to 180°F operating range. Verify all specifications match your equipment before ordering.

Q: Is the TH A8/A9 a polyurethane or rubber wheel?
A: The TH A8/A9 is an ultra-poly wheel, meaning it has a polyurethane tread bonded to a steel core. Polyurethane wheels are non-marking, durable, and suitable for both indoor and outdoor use on finished and rough floors.

Q: How do I verify that the TH A8/A9 is compatible with my pallet jack?
A: Compare your equipment dimensions against the wheel specifications: mounting plate size, and bolt hole pattern. If your equipment dimensions match these specifications, this wheel is compatible.

Q: What makes polyurethane wheels better than rubber or solid tires?
A: Polyurethane wheels are non-marking (no stains on flooring), naturally quiet, durable, and perform well on both smooth warehouse floors and rougher outdoor surfaces. They also provide good shock absorption and require minimal maintenance compared to rubber or pneumatic tires.

Q: How long do ultra-poly wheels typically last?
A: Ultra-poly wheel lifespan depends on load, floor conditions, and usage frequency. With normal warehouse use (loading docks, inventory movement, direct-store delivery), these wheels typically provide 2-4 years of service. Heavier loads and rough outdoor use may reduce lifespan; controlled indoor use may extend it.
