Frequently Asked Questions
Q: What are the key specifications for the PU AA-2.875X4 PMWB-D load roller assembly?
A: The PU AA-2.875X4 PMWB-D features a Black ultra polyurethane tread bonded to a machined steel hub with integrated sealed ball bearings. The bearing ID accommodates standard wheel axle configurations.
Q: Which Pallet Mule models does the PU AA-2.875X4 PMWB-D fit?
A: The PU AA-2.875X4 PMWB-D is designed for Pallet Mule AA5500 and AA5000 models. It also fits compatible Valu-Jack 5500 equipment. Verify your equipment model and lowered height specification match before ordering.
Q: What is the difference between PMWB-D and PMWB-N materials?
A: The PMWB-D uses black ultra polyurethane tread for general warehouse use and non-marking performance. The PMWB-N uses nylon crowned tread for higher durability in heavy-load or high-cycle applications. Polyurethane offers better traction on smooth floors. Nylon offers extended wear life.
Q: What are the cross-reference part numbers for the PU AA-2.875X4 PMWB-D?
A: The PU AA-2.875X4 PMWB-D supersedes the earlier AA-2.875X4 PMWB-D designation and is equivalent to the PU AA-2.875X4 PMWB-N variant. It also fits the GWK-PUAA-LW load wheel kit assembly. Confirm your part number matches before ordering to ensure correct fitment.
Q: How long does the PMWB-D tread last before replacement is needed?
A: Ultra polyurethane tread typically delivers service life in standard warehouse conditions. High-cycle operations or aggressive floors may require replacement. Inspect wheels quarterly for flat spots, chunking, or uneven wear. Sealed bearings do not require re-lubrication.
Q: How should the load roller assembly be stored?
A: Store in a clean, dry indoor environment protected from direct sunlight, extreme heat, and humidity. Keep sealed bearing surfaces free from debris. Store vertically or horizontally but avoid stacking heavy items on top to prevent hub deformation.
Q: What maintenance does the PU AA-2.875X4 PMWB-D require?
A: Sealed bearings require no re-lubrication. Inspect the assembly quarterly for signs of wear, flat spots, or loss of tread. Clean the tread surface regularly to maintain traction. Replace the assembly if bearing noise develops, tread is chunked or flat-spotted, or polyurethane separates from the hub.
