Frequently Asked Questions
Q: What type of bearing is the PU AA-64?
A: The PU AA-64 is a precision deep groove ball bearing with sealed case-hardened steel construction. It is manufactured to SAE 52100 bearing-grade specifications and features high carbon steel rings and balls. The sealed design protects internal components from contamination and extends bearing life in material handling environments.
Q: Which Pallet Mule models is the PU AA-64 bearing compatible with?
A: The PU AA-64 bearing is designed for Pallet Mule AA5000 and AA5500 series manual pallet jacks. It is sized specifically for OEM linkage assemblies in these models. Cross-referenced part numbers include AA-64 and PUAA-64. Verify your equipment model before ordering to ensure correct fitment.
Q: What materials are the PU AA-64 rings and balls made from?
A: Both the bearing rings and balls are manufactured from high carbon steel and case-hardened to SAE 52100 specification. This material grade provides superior hardness, wear resistance, and fatigue strength required for repeated lifting cycles in pallet jack applications.
Q: How do I know if the PU AA-64 bearing needs replacement?
A: Signs of bearing failure include grinding or squealing noises during operation, excessive play or wobbling in the bearing assembly, resistance or stiffness in rotation, or visible corrosion or damage to the bearing races. If present, the bearing should be replaced immediately to prevent damage to connected components.
Q: Are there cross-reference part numbers for the PU AA-64?
A: Yes. The PU AA-64 bearing is cross-referenced as AA-64 and PUAA-64. When ordering replacement parts, any of these designations will identify the same OEM bearing assembly. Confirm the bearing bore diameter and width match your equipment before purchase.
