Frequently Asked Questions
Q: What is the cross-reference part number for SU S9168-XL-A?
A: SU S9168-XL-A is the direct replacement for OEM part number SUS9168-XL-A. This is a Poly Load Wheel 97A Assembly constructed with Shore A97 polyurethane. Verify your original jack model and wheel bore before ordering to confirm fitment on your electric lift truck.
Q: Will SU S9168-XL-A fit my electric pallet jack?
A: SU S9168-XL-A is engineered specifically for electric lift trucks and features a 3.250 inch outer diameter, 4.422 inch width, and 2.1649 inch bore. Measure your existing wheel bore and compare dimensions before installation. This wheel is not compatible with manual hydraulic pallet jacks unless the jack has the same wheel bore diameter and load rating.
Q: What does Shore A97 polyurethane mean for this load wheel?
A: Shore A97 indicates the hardness and durability of the polyurethane compound. Higher Shore A ratings (97) provide greater abrasion resistance and load-bearing capacity. This Cushothane XL material is designed for heavy-duty warehouse environments and continuous industrial use with minimal deflection under load.
Q: How do I install SU S9168-XL-A on my electric lift truck?
A: Lower the jack completely and release all pressure. Locate the wheel axle bolt and remove the retaining clip or snap ring. Slide the old wheel assembly off, then slide SU S9168-XL-A onto the axle, ensuring the bore depth (0.79 inch) fully seats. Reinstall the retaining clip, then test under light load before full operation. Do not exceed the jacks rated load capacity.
Q: What maintenance is required for the SU S9168-XL-A load wheel?
A: Inspect wheels weekly for uneven wear, flat spots, cracks, or debris buildup. Clean the polyurethane tread with a damp cloth to remove warehouse dust and oils. Rotate wheels side-to-side every 200 operating hours to promote even wear. Replace when tread depth decreases below 1/8 inch or when the wheel no longer tracks straight, typically after 2 to 3 years of daily use depending on floor conditions.
Q: Can I use SU S9168-XL-A on wet or cold storage floors?
A: SU S9168-XL-A is a standard 97A polyurethane wheel suitable for typical warehouse floors. For wet floors or cold storage environments (below 40 degrees Fahrenheit), Superior recommends upgrading to a product with the -EZ designation, which features a High Traction polyurethane compound engineered for reduced slip on slippery surfaces and improved performance in cold conditions.
