Polyurethane Wheel Sku for Electric Trucks

Frequently Asked Questions

Q: What are the specifications of the 220012781 polyurethane wheel?
A: The 220012781 is a polyurethane wheel for electric lift trucks with a cast iron core and high-resilience polyurethane tread. The wheel is engineered to QT450 x 10 and GB/T-20 standards. Core material is cast iron with abrasion-resistant polyurethane tread suitable for load and drive wheel positions.

Q: Which electric lift truck models is the 220012781 compatible with?
A: The 220012781 is designed for electric pallet trucks and electric stackers that use this load and drive wheel configuration. Compatibility depends on exact mounting dimensions. Verify these dimensions match your equipment specifications before ordering.

Q: Why is the 220012781 suitable for low temperature environments?
A: The high-resilience polyurethane tread compound maintains flexibility and grip in low temperature warehouses and cold storage operations. Unlike standard rubber or lower-grade polyurethane, this formulation does not harden or lose traction as ambient temperature drops, ensuring reliable operation in freezer and refrigerated environments.

Q: What is the expected service life of the 220012781 polyurethane wheel?
A: Service life depends on load capacity utilization, floor conditions, and operating environment. High-resilience polyurethane typically provides 1500 to 3000 operating hours before significant tread wear occurs. Inspect periodically for tread separation, hardening, or flat spots. Replace when tread depth is visibly reduced or when bonding between tread and core begins to fail.

Q: How does the cast iron core affect wheel durability?
A: Cast iron cores offer excellent load-bearing rigidity and impact resistance. The QT450 x 10 specification ensures the cast iron meets specific tensile strength and ductility requirements for reliable bonding with the polyurethane tread under dynamic loading.

Q: Is the 220012781 available with different hardness ratings?
A: The 220012781 is a fixed specification part with high-resilience polyurethane tread formulation. No alternate hardness or compound options are available under this part number. Contact manufacturer for alternative part numbers if your application requires different tread hardness.

Q: How should this wheel be stored?
A: Store in a cool, dry location away from direct sunlight and extreme temperatures. Protect from oils, solvents, and chemicals that may degrade polyurethane. Store upright or on edge to prevent flat spotting during long-term storage.
