Frequently Asked Questions
Q: What are the specifications for the PU AA-3X4 PMWB load roller?
A: The PU AA-3X4 PMWB features a 70D durometer ultra-polyurethane tread, aluminum hub, 20 mm bearing inner diameter, and a pre-installed stainless steel ball bearing. This construction provides durable, corrosion-resistant service in manual pallet jack applications.
Q: Which Pallet Mule models does the PU AA-3X4 PMWB fit?
A: The PU AA-3X4 PMWB is designed for Pallet Mule (Wesley) manual pallet jack models AA5000 and AA5500. Confirm your equipment serial number matches these models before purchasing.
Q: What does 70D durometer mean for the PU AA-3X4 PMWB tread?
A: The 70D durometer rating indicates the hardness and load-bearing capacity of the ultra-polyurethane tread. Higher durometer provides greater resistance to wear, cutting, and compression under heavy manual pallet jack loading, making it suitable for frequent or high-load material handling.
Q: What are the cross-reference part numbers for the PU AA-3X4 PMWB?
A: The PU AA-3X4 PMWB-D is also referenced as PUAA-3x4 PMWB, AA-3x4 PMWB, PTAA-3x4 PMWB, PUAA3x4 PMWB, AA3x4 PMWB, and PTAA3x4 PMWB. It is equivalent to parts marked as AA3x4 or 3x4 with Wesley or Pallet Mule designation.
Q: Why choose stainless steel bearing in the PU AA-3X4 PMWB?
A: The pre-installed stainless steel ball bearing resists corrosion and extends service life compared to standard steel bearings. Stainless steel is especially beneficial in wet, cold storage, or corrosive environments where manual pallet jacks operate.
Q: How long does the PU AA-3X4 PMWB load roller last?
A: The 70D durometer polyurethane and stainless steel bearing provide extended service life. Lifespan depends on load volume and floor conditions. Replace if tread shows flat spots, significant wear, or if bearing develops noise or resistance to rotation.
