220012781

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. The part number is 220012781 with no available cross-reference part numbers. Core material is steel with cast iron construction, and the tread is abrasion-resistant polyurethane suitable for load and drive wheel positions.

Q: Which electric lift truck models is the 220012781 compatible with?
A: The 220012781 fits electric pallet trucks and electric stackers that use this load and drive wheel configuration. Verify the wheel bore diameter and tread width dimensions match your equipment specifications before ordering, as compatibility depends on exact mounting dimensions and core type. This wheel is designed for general electric lift truck applications across multiple OEM brands.

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 for tread separation, hardening, or flat spots periodically. 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 compared to steel core alternatives?
A: Cast iron cores offer excellent load-bearing rigidity and impact resistance in heavy-duty applications but are slightly heavier than equivalent steel cores. 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 SKU. If your application requires different tread hardness or material properties, contact us to verify alternative part numbers that may fit your equipment.
