Frequently Asked Questions
Q: What are the specifications and dimensions of the PU AA-52 exit roller?
A: The PU AA-52 exit roller has a 2.875 inch nominal diameter, 4.00 inch length, and 0.75 inch mounting bore. It features polyurethane tread at 95 Shore A hardness bonded to an aluminum alloy or steel core, with grease-sealed bearing construction rated for 1600 lbs static load capacity.
Q: Which Pallet Mule models are compatible with this exit roller?
A: The PU AA-52 is designed for Pallet Mule AA5000 and AA5500 manual pallet jacks, mounted axially at the fork exit. It functions as a load-supporting component in the lower frame assembly.
Q: What alternate part numbers can be used for this exit roller?
A: Cross-reference part numbers for this roller include AA-52, PU AA-52, PUAA-52, and AA-52-2.9. All of these numbers reference compatible variants or equivalent rollers for the same application.
Q: What is the material composition of the polyurethane tread?
A: The tread is 95 Shore A hardness polyurethane, which provides good durability and grip for load support. The tread is chemically bonded to either an aluminum alloy or steel core depending on the production batch.
Q: What is the expected lifespan of this roller?
A: Polyurethane rollers with grease-sealed bearings typically last 2 to 5 years under moderate warehouse use, depending on floor conditions and load frequency. Rollers used in high-traffic environments or on rough surfaces may wear faster. Replace when tread becomes scored, flattened, or hardened.
Q: Does the core material affect performance or compatibility?
A: Both aluminum alloy and steel core options meet OEM performance specifications. Steel cores provide greater rigidity and load capacity in demanding applications, while aluminum alloy cores reduce weight. Either core type is a direct OEM replacement for AA5000 and AA5500 models.
