Frequently Asked Questions
Q: What are the dimensions and cross-reference part numbers for GW 528?
A: GW 528 is a load wheel with nominal dimensions of 3.250 inches diameter by 6.375 inches width (82.55 mm x 161.92 mm). Cross-reference part numbers include GW528-A, GP 528-A, GW528A, GP 528A, and 528A. All these part numbers supply identical wheels with the same diameter, width, and bearing specifications. Bearing ID is 25.000 inches. Use any of these cross-references when ordering replacement wheels.
Q: Is GW 528 compatible with electric and manual pallet jacks?
A: GW 528 is designed for electric lift truck and pallet jack applications. The wheel is suitable for electric lift jacks. Verify your jack model and wheel mounting specification (bearing ID, width, and diameter) match the GW 528 profile before installation. Some manual jacks may use different wheel sizes, so do not assume GW 528 fits all pallet jack types.
Q: What is the polyurethane grade and durometer hardness of GW 528?
A: GW 528 is constructed from 95A Shore durometer polyurethane, industrial grade. This hardness provides an optimal balance between load capacity, traction, and longevity. The wheel resists compression under heavy loads while maintaining flexibility for shock absorption on rough or uneven warehouse floors. 95A Shore is standard for lift truck and pallet jack wheels operating in industrial environments.
Q: How do I install GW 528 wheels on my pallet jack?
A: Lift the jack on a sturdy stand to remove weight from the wheels. Remove fasteners or clips securing the old wheel to the axle. Slide the old wheel off the bearing axle. Clean the axle shaft and bearing bore to remove dust and debris. Slide the new GW 528 wheel onto the axle, ensuring the bearing ID (25.000 inches) aligns properly with the axle diameter. Reinstall fasteners or clips securely. Do not over-tighten, which can damage the bearing or polyurethane. Test the wheel rotation before using the jack.
Q: When should I replace GW 528 wheels, and what are signs of wear?
A: Replace GW 528 wheels when you observe flat spots or uneven wear, loss of traction or slipping on smooth floors, visible chunks missing from the polyurethane, or wheel wobble during operation. Typical wheel lifespan is 3 to 5 years depending on daily usage intensity and floor conditions. Worn wheels reduce lift truck stability and increase accident risk, so replace them before they fail completely. Store replacement wheels in a cool, dry location to prevent polyurethane degradation.
