Frequently Asked Questions
Q: What are the dimensions of the 78673 load wheel?
A: The 78673, designed to fit standard Big Joe electric pallet jack configurations. Verify your equipment's wheel dimensions match before ordering to ensure proper fit and operation.
Q: What material is the 78673 tread made from?
A: The 78673 uses 95 Shore A polyurethane tread bonded to a high carbon steel core. This mid-range hardness formulation provides excellent abrasion resistance and reliable grip on dry concrete floors typical in warehouses and loading docks.
Q: What bearing type does the 78673 use?
A: The 78673 is equipped with sealed deep groove ball bearings made from chrome steel SAE 52100. The sealed design protects bearings from dust, moisture, and warehouse contaminants, significantly extending service life in demanding environments.
Q: What is the load rating for the 78673?
A: The 78673 is rated for static load per wheel. This rating assumes proper installation and even load distribution across all wheels on the pallet jack. Exceeding the rated load may result in bearing failure or structural damage.
Q: How long will the 78673 polyurethane tread last?
A: With 95 Shore A hardness, the polyurethane tread typically lasts 2-5 years depending on usage frequency, floor conditions, and maintenance. More intensive daily use shortens lifespan, while lighter intermittent use extends it. Regular inspection for wear is recommended.
Q: Can the 78673 be used on wet or oily floors?
A: Standard 95 Shore A polyurethane provides reduced traction on wet, slippery, or oily surfaces. For wet floor or cold storage applications, contact us about high-traction polyurethane alternatives with improved grip in challenging conditions.
Q: Is the 78673 compatible with all Big Joe pallet jacks?
A: The 78673 is designed for Big Joe electric pallet jacks with matching wheel dimensions. Verify your equipment's specification plate or manual to confirm compatibility before purchase. Consult Big Joe documentation for your specific model.
Q: What should I know about maintenance for the 78673?
A: Keep wheels clean and inspect regularly for cuts, splits, or excessive wear. The sealed bearings require no lubrication. Store in a cool, dry location when not in use. Avoid prolonged exposure to direct sunlight or extreme temperatures, which can degrade polyurethane.
