Frequently Asked Questions
Q: What does the XL designation mean on SU 9164-XL?
A: XL typically indicates a larger diameter or wider load rating. SU 9164-XL features a cast iron core with chemically bonded polyurethane tread, engineered for heavier-duty electric pallet truck applications than the standard SU 9164. The cast iron core provides greater structural strength under sustained load compared to a steel hub.
Q: Is SU 9164-XL compatible with trucks that use SU 9164?
A: Not always. Before substituting SU 9164-XL for SU 9164, verify the hub bore diameter, mounting method, and load rating with your truck manufacturer. The XL version may be heavier or have a different center bore. Installing an incompatible wheel can cause misalignment, bearing preload issues, or insufficient clearance. Do not assume cross-compatibility.
Q: What is 92 Shore A tread hardness and why is it specified?
A: 92 Shore A is a durometer reading that measures polyurethane hardness. Higher hardness (92 vs. 80, for example) means greater wear resistance and reduced slip on smooth floors but a stiffer ride. For warehouse use on polished concrete, 92 Shore A provides longer wheel life. If the truck is used on uneven or textured floors, a softer compound may offer better grip.
Q: What cross-reference part numbers should I know for SU 9164-XL?
A: SU 9164-XL is cross-referenced as SU S9164-XL, SUS9164-XL, and SU-S9164-XL. When ordering from different distributors or checking inventory, use all four part numbers. Some suppliers may list it under only one variation. Always confirm the hub material (cast iron), tread type (polyurethane), and hardness spec (92 Shore A) when ordering to ensure you receive the correct part.
Q: Is SU 9164-XL press-fit or bolt-on?
A: SU 9164-XL is engineered for standard press-fit mounting onto the truck axle shaft. A hydraulic press or mechanical wheel puller is required for installation. Do not attempt to drive the wheel onto the shaft with a hammer or mallet. Improper installation can damage the bearing and cause wheel wobble or premature failure.
Q: How often should SU 9164-XL wheels be inspected for wear?
A: Inspect monthly in heavy-use environments (over 40 hours per week). Look for flat spots, cracks radiating from the hub, or tread separation. Use a straightedge to check for run-out or radial wobble. Even slight separation between tread and hub indicates bond failure. At the first sign of separation, prepare to replace the wheel to prevent it from coming loose during operation.
