PU AA-2X4 PW/B

Frequently Asked Questions

Q: What does the PU AA-2X4 PW/B load wheel assembly fit?
A: The PU AA-2X4 PW/B is a 2 x 4 poly load wheel assembly designed for Pallet Mule manual pallet jack models. The designation refers to 2 inch diameter by 4 inch width. Verify your equipment model and existing wheel dimensions match these specifications before ordering.

Q: What are the dimensions of the PU AA-2X4 PW/B poly wheel assembly?
A: This load wheel assembly is 2 inches in diameter and 4 inches in width. These dimensions are standard for many Pallet Mule manual pallet jack models. Measure your existing wheel to confirm the diameter and width match before ordering this assembly.

Q: What does the PW/B designation mean on this wheel assembly?
A: PW indicates poly wheel (polyurethane or similar engineered polymer tread material), and B typically refers to the bearing or assembly configuration. This designation helps distinguish this wheel type from steel wheels or wheels with different bearing specifications in the Pallet Mule product line.

Q: What are the material properties of poly load wheels compared to steel wheels?
A: Poly load wheels offer better shock absorption and quieter operation than steel wheels. They provide good grip on smooth warehouse floors and are more forgiving on concrete surfaces. Poly wheels typically last 2 to 3 years under normal use. They are lighter than steel wheels and suitable for general-purpose material handling in most indoor environments.

Q: How do I maintain the PU AA-2X4 PW/B poly wheel assembly?
A: Inspect the poly tread regularly for flattening, cracking, or chunks missing. Keep the wheel and bearing bore free of debris and excess dirt. Poly wheels do not require lubrication of the tread itself, but sealed bearings should not be forcibly greased. Replace the assembly when the tread is worn flat or if the wheel no longer rolls smoothly.
