Frequently Asked Questions
Q: What are the specifications for the PU AA-8X2 PMWB-HD steer wheel assembly?
A: The PU AA-8X2 PMWB-HD is a steer wheel assembly with ultra-polyurethane tread on a CNC-machined anodized aluminum hub. The bearing bore includes pre-installed precision bearings.
Q: Which pallet jack models is the PU AA-8X2 PMWB-HD compatible with?
A: This assembly is designed for Pallet Mule AA5000 and AA5500 series manual pallet jacks. It supersedes the earlier AA-8x2 PMWB-HD designation and replaces the AA-8x2 PMWB part number.
Q: What tread material does this steer wheel use and why does it matter?
A: The tread is ultra-polyurethane, which offers greater grip and wear resistance on warehouse and concrete floors compared to steel wheels. Polyurethane wheels generate less noise and vibration during operation.
Q: How does the PU AA-8X2 PMWB-HD compare to the steel tread version?
A: The PMWB-HD features polyurethane tread with an aluminum hub, while the PU AA-8x2 SMWB uses steel tread and steel hub construction. The polyurethane version provides better traction and a smoother ride, while the steel version offers maximum durability in high-impact environments.
Q: What bearing maintenance is required for this assembly?
A: The assembly includes pre-installed precision ball bearings with a bearing bore. These bearings require no additional lubrication or maintenance during normal warehouse operation.
Q: Is this a complete steer wheel assembly ready for use?
A: Yes, this is a complete assembly that includes the wheel, pre-installed bearings, and all necessary mounting hardware. It is a direct replacement unit designed to fit Pallet Mule AA5000 and AA5500 series equipment.
