Frequently Asked Questions
Q: What does the -A designation mean for the 0000-971760-A?
A: The -A suffix indicates this is an assembly version that includes the polyurethane wheel bonded to a precision bearing and axle interface. This is a complete load wheel assembly ready for your equipment, as opposed to a bare wheel component. The assembly configuration ensures the bearing is properly seated and the wheel is balanced before shipment.
Q: What are the exact dimensions of this wheel?
A: The wheel measures.
Q: What bearing type and material does this wheel use?
A: The wheel uses precision-sealed ball bearings with a chrome steel outer race. Chrome steel is corrosion-resistant and maintains rigidity under the dynamic loads of electric lift trucks. The sealed bearing design prevents dirt and moisture ingress, extending bearing service life in wet dock and outdoor environments.
Q: Why is the precision-machined steel core significant?
A: The precision-machined steel core ensures the wheel bore is concentric with tight tolerances, which minimizes radial runout and wobble during operation. Poor machining tolerance causes uneven polyurethane wear and premature bearing failure. The machined finish also provides a stable surface for the sealed bearing to seat properly, reducing axial play and noise.
Q: How does 95A Shore D hardness compare to other load wheels?
A: The 95A Shore D polyurethane is a mid-range hardness that balances load capacity with traction. Compared to 97A wheels, the 95A compound provides slightly better grip on wet or contaminated concrete but may show faster tread glazing in continuous dry-floor operation. This hardness is ideal for equipment working across varied floor conditions.
Q: What is the expected service life of this wheel assembly?
A: In typical heavy-duty electric lift truck environments, expect 2-4 years of service before the polyurethane tread becomes too glazed for safe operation. The sealed ball bearing typically lasts 3-5 years before noise or wobble appears. Lifespan varies based on load weight, floor conditions, and daily runtime hours. Monitor tread grip quarterly and replace when traction becomes unreliable.
Q: What equipment compatibility should I verify before purchasing?
A: Verify the axle diameter and bearing type with your equipment manual or original parts documentation. Incompatible installation can cause equipment damage or safety hazards.
