Frequently Asked Questions
Q: What are the cross-reference part numbers for the GW 548?
A: The GW 548 is equivalent to GP 548-A and GP548-A (note: GP part numbers are common Goodyear/generic cross-references). Always verify the exact revision letter and bearing configuration with your supplier, as these part families have multiple iterations.
Q: What is the difference between the GW 548 and GW 548-A?
A: The GW 548 core product is a 4 x 2 polyurethane load wheel with 92A durometer tread bonded to a steel core, using pressed construction with sealed bearing and integral shaft seals. The GW 548-A is the complete assembly version. Verify with your supplier whether you need the wheel only or the full assembly.
Q: Does the GW 548 wheel include bearings?
A: No. The wheel does not include bearings. You must supply compatible sealed bearings matching your shaft diameter (typically 19.05mm or 0.75 inch for many electric jack models). Verify bearing ID before pressing the wheel onto your shaft.
Q: What electric pallet jack models accept the GW 548 wheel?
A: The GW 548 fits Crown GPW series jacks and equivalent OEM equipment requiring 4 x 2 polyurethane wheels with 92A durometer. Check your jack manual for the original wheel part number and confirm bearing bore size before purchasing.
Q: Is the pressed construction permanent or can the GW 548 be disassembled?
A: The polyurethane tread is permanently bonded to the steel core using pressed construction. Attempting to separate the tread from the core will destroy the wheel. If the tread is worn but the core is intact, the entire wheel must be replaced.
Q: How long does the 92A polyurethane tread last on a GW 548 wheel?
A: 92A polyurethane wheels typically last 12-18 months under continuous warehouse use. They wear faster than 95A compounds but provide better grip on smooth concrete. Inspect quarterly for tread depth and surface cracks; replace when tread is below 0.25 inches or visible damage appears.
