Frequently Asked Questions
Q: Is SU 9141-A compatible with Superior pallet jack models?
A: SU 9141-A is an aftermarket load wheel assembly designed for electric pallet truck applications. Verify compatibility with your specific pallet jack model by checking the original equipment manufacturer part number. The 20mm precision bore and sealed ball bearings work on equipment with matching hub specifications.
Q: What are the cross-reference part numbers for SU 9141-A?
A: SU 9141-A cross-references include Superior SU9141-A, SU 9141-XL-A, SU9141XL, GW 9141-A, and 9141XL. Always verify the exact part number on your equipment before ordering to ensure proper fitment and function.
Q: What is the difference between polyurethane 95A and other hardness ratings for load wheels?
A: SU 9141-A features polyurethane 95A Shore hardness, which provides a balance of grip and durability for typical warehouse floor conditions. Higher hardness (97A or higher) offers better wear resistance on rough surfaces but less cushioning. Lower hardness (below 90A) improves traction but wears faster under heavy loads.
Q: How do I replace the SU 9141-A load wheel assembly?
A: Raise the pallet jack on blocks, remove the cotter pin or retaining clip from the 20mm bore, slide the old wheel assembly off the axle, and slide the new SU 9141-A assembly onto the axle. Reinstall the retaining clip or cotter pin and verify the wheel spins freely. Do not operate the jack until all wheels are properly installed and secured.
Q: What floor surfaces is the cast iron core with polyurethane 95A tread rated for?
A: The SU 9141-A assembly with cast iron core and 95A polyurethane tread performs well on smooth concrete, asphalt, and sealed warehouse floors. The sealed ball bearings prevent debris contamination. Avoid prolonged use on very rough or wet surfaces where higher hardness wheels (97A or XL formulations) would be more durable.
Q: What is the maximum load capacity of the SU 9141-A wheel assembly?
A: The SU 9141-A load wheel is sized for standard electric pallet truck applications with 3.25 inch diameter and 6.5 inch width. Maximum load depends on the number of wheels on the truck and the jack model. Refer to your equipment manufacturer specifications for total load capacity. Do not exceed the rated capacity to prevent wheel damage and safety hazards.
