Frequently Asked Questions
Q: What are the metric dimensions of the 4081639 load wheel?
A: The 4081639 measures . Verify these dimensions match your equipment specifications before ordering to ensure proper fit and performance.
Q: What is the 95A durometer rating and why is it specified for this wheel?
A: The polyurethane tread is rated at 95A Shore A hardness, providing balanced wear resistance and floor grip suitable for electric pallet truck and reach truck applications. This rating offers durability while maintaining adequate cushioning for smooth load handling and vibration reduction.
Q: Are the roller bearings pre-lubricated and do they require maintenance?
A: Yes, the wheel assembly includes factory-installed lubricated roller bearings with sealed design that require no field service or relubrication. The sealed bearings are designed for extended operational life and reduced maintenance downtime.
Q: What function do the integrated string guards serve?
A: The integrated string guards prevent rope, plastic strapping, packaging wrap, and other debris from tangling around the wheel assembly during operation. They protect the bearing seals by blocking contaminant entry and reduce potential damage from debris entanglement.
Q: Which equipment types and applications is this wheel designed for?
A: The 4081639 load wheel is engineered for electric pallet trucks and reach trucks used in warehouse, distribution, and light manufacturing environments. Confirm your specific equipment model is compatible before purchasing.
Q: What is the typical service life and wear replacement threshold for this wheel?
A: Service life varies based on usage intensity, floor conditions, and load cycles. The sealed bearing design and string guards extend operational life. Replace the wheel when polyurethane tread wear reaches approximately 50% of original thickness or when visible damage is observed.
