Frequently Asked Questions
Q: What does XL mean on the SU 254-XL load wheel?
A: XL designates extra-large tread width on a standard five-inch diameter wheel. The SU 254-XL has a 4.5 inch tread width compared to 3.75 inch on the standard SU 254. The wider tread distributes load over a larger surface area and reduces ground pressure, making it suitable for softer floor surfaces or heavy-duty applications.
Q: Can I use the SU 254-XL on a truck designed for the standard SU 254?
A: No, do not substitute. The wider tread can contact the truck frame or steering linkage depending on your truck model. If you have a standard SU 254 truck and want the wider tread benefit, consult the truck manufacturer for frame clearance. Some trucks allow the XL version; others do not.
Q: What is the load rating for the SU 254-XL wheel?
A: The SU 254-XL supports up to 5000 pounds per wheel under standard duty conditions. The extra tread width improves stability and grip but does not increase the structural load capacity. Overloading causes premature bearing wear and hub cracking.
Q: Does the SU 254-XL work on warehouse concrete, tile, and ramp surfaces?
A: Yes, the polyurethane tread on the SU 254-XL performs well on concrete, smooth tile, and sealed ramps. On uneven or outdoor surfaces, the wider tread provides better shock absorption. Do not use on soft asphalt in warm weather; the tread can deform and stick.
Q: What bearing type does the SU 254-XL use and can I replace it in the field?
A: The SU 254-XL uses sealed deep-groove ball bearings, 0.75 inch bore diameter. Bearings are press-fitted to the hub and require a bearing puller and press for field replacement. If bearings fail, most technicians replace the entire wheel and hub assembly rather than attempting a field bearing swap.
Q: How often should I inspect the SU 254-XL wheels during routine maintenance?
A: Inspect the SU 254-XL visually every 500 hours of operation or monthly, whichever comes first. Check for flat spots, tread separation, cracks, and bearing play. Spin each wheel by hand to ensure smooth rotation with no grinding noise. Replace immediately if you detect grinding sounds or wheel wobble.
