Frequently Asked Questions
Q: What are the metric dimensions of the HY 4081639 load wheel?
A: The HY 4081639 measures 85x110mm. These metric dimensions specify the wheel core size (85mm diameter core, 110mm face width). Verify these dimensions match your equipment before ordering to ensure proper fit and performance.
Q: What is the durometer rating and why is 95A specified?
A: The polyurethane tread is 95A Shore A hardness, providing standard wear resistance and floor grip for electric pallet truck and reach truck applications. The 95A rating balances durability with adequate cushioning for smooth load handling and reduced vibration.
Q: Are the roller bearings pre-lubricated or do they require service?
A: Factory-installed lubricated roller bearings come with initial lubrication and sealed design requiring no field service. Bearings are sealed for extended life and reduced maintenance. Do not attempt to relubricate sealed bearing assemblies.
Q: What application range does this wheel cover?
A: The HY 4081639 is designed for electric pallet truck and reach truck applications. It handles typical warehouse, distribution, and light manufacturing environments. Do not use for heavy-duty outdoor or extreme temperature applications without confirming equipment specification.
Q: What do the integrated string guards protect?
A: Integrated string guards prevent rope, strapping, plastic wrap, and other debris from tangling around the wheel assembly and axle during operation. They reduce debris entanglement damage and extend bearing seal life by blocking contaminant entry.
Q: How long does this load wheel typically last in service?
A: Lifespan varies with usage intensity, floor conditions, and load cycles. The factory-installed sealed bearings and integrated string guards provide extended service life. Replace when polyurethane tread wear reaches approximately 50 percent thickness or visible damage occurs.
