Frequently Asked Questions
Q: What are the complete specifications for the PU AA-8X2 SMWB steer wheel?
A: The PU AA-8X2 SMWB is an 8 inch diameter by 2 inch width complete steer wheel assembly with steel tread and steel hub construction. The bearing bore is 20mm with press-fit ball bearings included. This is a fully assembled wheel ready for use.
Q: What pallet jack models does the PU AA-8X2 SMWB fit?
A: The PU AA-8X2 SMWB is a direct replacement for Pallet Mule AA5000 and AA5500 series manual pallet jacks. Confirm your equipment model matches before ordering.
Q: Why choose steel tread over polyurethane for this wheel size?
A: Steel tread provides superior durability in high-impact warehouse environments, rough outdoor surfaces, and environments with sharp debris or aggregate. Steel wheels are harder and more resistant to punctures, cuts, and wear than polyurethane alternatives.
Q: What bearing type is used in this assembly?
A: The PU AA-8X2 SMWB uses press-fit ball bearings with a 20mm bearing ID. These bearings are pre-installed at the factory and sealed within the steel hub for reliable operation without additional maintenance.
Q: How does this steel wheel assembly differ from the polyurethane version?
A: The SMWB uses steel tread and steel hub for maximum durability and resistance to wear, while the PMWB-HD uses polyurethane tread on an aluminum hub for improved traction and reduced noise. Choose steel for harsh environments; choose polyurethane for smooth floors and operator comfort.
Q: Is the PU AA-8X2 SMWB a complete assembly or does it require additional parts?
A: This is a complete wheel assembly with pre-installed bearings and mounting hardware included. No additional components are required for direct replacement on the steer wheel axle.
