Frequently Asked Questions
Q: What manual pallet jack models does part number PU AA-2X4 SW fit?
A: The PU AA-2X4 SW is engineered for Pallet Mule manual pallet jacks configured for both left and right fork use. Always verify your equipment model and existing roller dimensions before ordering to ensure proper fit and compatibility.
Q: What are the key specifications for the PU AA-2X4 SW steel roller?
A: Roller. Material is carbon steel meeting ASTM A36 structural standards. The assembly includes sealed precision ball bearings and an industrial corrosion-resistant finish.
Q: Why is carbon steel and ASTM A36 compliance important?
A: ASTM A36 ensures minimum tensile and yield strength required for load-bearing applications. For pallet jacks, this specification guarantees the roller will not deform or fail under normal warehouse working loads, providing consistency and reliability across production batches.
Q: What is the bearing bore size and why does it matter?
A: The bearing bore. This size must match your equipment axle diameter precisely. Incorrect bore sizing results in either excessive play (roller spins freely without engagement) or binding that prevents smooth rotation. Always measure your axle before ordering.
Q: How long does a steel roller assembly typically last?
A: Carbon steel rollers typically provide 4 to 6+ years of service under normal warehouse use, especially with sealed bearings preventing contamination and extending bearing life. Replace the assembly if you observe surface rust pitting, rough or noisy rotation, or visible bending or deformation.
Q: What is the purpose of the corrosion-resistant finish?
A: The finish protects the carbon steel from warehouse humidity, wet floors, and chemical exposure that cause rust and pitting. This coating extends useful life and maintains smooth operation. Inspect periodically for finish wear in high-traffic contact areas; localized surface rust may indicate the need for replacement.
