Product Description
This load wheel kit features two Ultra-Poly (70D) Load Wheel Assemblies equipped with bearings, axles, and fasteners for enhanced durability and performance. Designed for use on various floor surfaces, these non-marking wheels ensure smooth and efficient operation, making them suitable for warehouses and factories. The advanced 70D durometer provides superior strength, outlasting standard 92A polyurethane wheels without damaging your floors.
Compatibility: Fits pallet jacks made by Uline, model H3762. SKU: GWK-3762-LW

Frequently Asked Questions
Q: What pallet jack models is GWK-3762-LW compatible with?
A: GWK-3762-LW is engineered for Uline model H-3762 pallet jacks with serial number 7-000000 and higher. Always verify the serial number on your jack nameplate located on the frame or handle assembly. Earlier serial numbers may have different axle diameters or bearing configurations. If your jack serial falls below 7-000000, contact Uline technical support for the correct cross-reference part number.
Q: Does GWK-3762-LW include steer wheels or only load wheels?
A: GWK-3762-LW is a load wheel kit only. It contains two Ultra-Poly 70D Load Wheel Assemblies with bearings, axles, and fasteners. Steer wheels are not included. If your H-3762 jack requires steer wheel replacement, you must order steer wheels separately or select GWK-3762-CK which is the complete kit with both load and steer wheels included.
Q: What is the wheel hardness specification and why does it matter?
A: GWK-3762-LW wheels are 70 Shore D durometer as measured by ASTM D2240 standard. This means they are harder and more durable than standard 92A wheels. Harder wheels resist permanent deformation under sustained loads, reduce rolling resistance, and extend service life in high-use environments. Disadvantage: harder wheels provide less shock absorption on rough floors. Use 70D for facilities with smooth concrete and continuous heavy-load operation.
Q: Are GWK-3762-LW wheels non-marking on sealed floors?
A: Yes. GWK-3762-LW wheels have a non-marking Ultra-Polyurethane finish and do not discolor or stain sealed concrete, epoxy, or polished floors. However, do not mix them with steel wheels on the same jack. If you switch from polyurethane to steel wheels for factory use, replace all four wheels or you risk uneven rolling and floor marking from steel wheels while other wheels remain non-marking.
Q: What bearing material is used in GWK-3762-LW?
A: GWK-3762-LW uses high-carbon steel bearing races with chrome steel balls. These bearings support working loads of 4,000 to 5,000 pounds per wheel assembly. The bearing races are sealed but not waterproof. Do not operate the jack in flooded areas or immediately after washdown. Moisture causes corrosion of bearing surfaces, leading to increased rolling resistance, noise, and eventual bearing seizure.
Q: How do I know when to replace GWK-3762-LW load wheels?
A: Replace load wheels when you observe flat spots on the running surface, visible cracks or chunks missing from the wheel body, grinding or squeaking sounds during operation, the jack pulling hard to one side during forward movement, or reduced lifting height caused by worn wheels. Inspect load wheels monthly if the jack operates daily. Once removed, wheels cannot be reused. Do not attempt to grind flat spots smooth as this weakens the wheel structure.
