Frequently Asked Questions
Q: What are the key specifications of the AA-52 exit roller?
A: It includes 95 Shore A polyurethane tread bonded to aluminum alloy or steel core with grease-sealed bearing construction.
Q: Which equipment models are compatible with the AA-52?
A: The AA-52 is designed as a direct replacement for Pallet Mule AA5000 and AA5500 manual pallet jacks, mounted at the fork exit for load support.
Q: What alternate part numbers reference this roller?
A: Equivalent part numbers include PUAA-52 and AA-52-2.9, which reference the same product or compatible variants.
Q: What material composition makes up the roller tread?
A: The tread is 95 Shore A hardness polyurethane, chemically bonded to either aluminum alloy or steel core depending on production batch, providing durability and reliable load support.
Q: What is the typical service 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. Replace when tread becomes scored, flattened, or hardened from wear.
Q: Does core material selection affect roller performance?
A: Both aluminum alloy and steel core options meet performance specifications for the AA5000 and AA5500 equipment. Steel cores offer greater rigidity for demanding loads, while aluminum alloy cores provide weight reduction. Both are direct replacements.
