Frequently Asked Questions
Q: What is the bearing bore size for GW 820-A and will it fit my 17mm axle?
A: GW 820-A has a 17mm (0.669 inch) bearing ID with precision sealed ball bearings already installed. It is designed for direct press fit onto 17mm axles used in most electric pallet jacks. Verify your axle diameter before installation. If your jack uses a different bore size, this wheel will not fit without modification.
Q: Is GW 820-A equivalent to any other manufacturer part numbers?
A: GW 820-A carries OEM part number GW820. It may cross-reference with similar 3.25 x 4.5 poly load wheels from other manufacturers, but always verify the bearing ID (17mm), width (4.5 inch), and durometer (95A) before substituting. Different brands may have slight tolerance variations.
Q: What load capacity and durometer rating does the GW 820-A wheel have?
A: GW 820-A features 95A tread hardness polyurethane, which is standard for electric lift truck applications. The 3.25 inch diameter x 4.5 inch width design supports typical pallet jack loads. Check your equipment manual for the specific load rating of your jack model, as wheel capacity depends on axle design and bearing quality.
Q: How do I diagnose if my GW 820-A wheel bearings are worn out?
A: Spin the wheel by hand. It should rotate smoothly for several seconds without grinding noise or roughness. If the wheel stops quickly, feels gritty inside, or makes squeaking sounds when the jack operates, the sealed ball bearings are likely failing. Replace the entire wheel assembly. Do not attempt to repack sealed bearings.
Q: What is the difference between GW 820-A and GW 820-AA?
A: GW 820-A is the wheel assembly with pre-installed sealed bearings ready to press onto your axle. GW 820-AA is a complete load wheel assembly that may include axle hardware and additional mounting components. Check your jack configuration before ordering. Both have the same 3.25 x 4.5 dimensions and 17mm bearing ID.
