Frequently Asked Questions
Q: Is the SU 9X5X5-SF-R-A a complete wheel assembly, and does it come pre-assembled?
A: Yes. The SU 9X5X5-SF-R-A includes an industrial natural rubber drive tire permanently mounted on a machined steel hub. The assembly is ready to install directly onto your lift truck or pallet jack axle. No additional pressing, machining, or assembly is required.
Q: What are the cross-references for the SU 9X5X5-SF-R-A?
A: The SU 9X5X5-SF-R-A cross-references include Superior SU9X5X5SFRA. Some legacy systems may reference this as SU 9X5X5-SF-R-A (with hyphens). Always verify part numbers in your equipment manual to confirm compatibility.
Q: What is the bore size of the hub on the SU 9X5X5-SF-R-A?
A: The hub bore (inner diameter) is 5.000 inches (127 mm). Verify that your lift truck axle or wheel pin measures 5 inches in diameter before installation. If your axle is oversized or undersized, you will need a different hub size or custom machining.
Q: What is the maximum load rating for the SU 9X5X5-SF-R-A, and is it suitable for heavy industrial use?
A: The SU 9X5X5-SF-R-A is rated for 3020 lbs at 6 miles per hour maximum speed. This assembly is designed for industrial electric lift trucks and pallet jacks in warehouse and light manufacturing environments. It is not rated for outdoor use, extreme temperature swings, or continuous high-speed operation. The steel hub and rubber compound will degrade in direct sunlight or freezing conditions.
Q: How do I inspect the hub on the SU 9X5X5-SF-R-A for damage?
A: Remove the wheel and inspect the hub bore (inner diameter) for cracks, scoring, or enlarged diameter. Clean the bore with a dry cloth. The bore should be smooth and uniform. If you see visible cracks radiating from the bore, or if the bore diameter is enlarged (over 5.010 inches), replace the entire wheel assembly. A damaged hub cannot be safely repaired.
Q: What maintenance keeps the SU 9X5X5-SF-R-A in service longer?
A: Monthly: Inspect tire for cracks, bulges, or missing chunks. Check that the wheel sits flush on the axle with no wobble or rock. Clean the hub bore of dirt and debris. Do not store in direct sunlight or extreme heat. Replace tires when tread depth is less than 1/4 inch or rubber compound becomes hard and brittle. Rotate tires between front and rear positions every 6 months if possible to extend lifespan.
