Frequently Asked Questions
Q: What is the difference between the SU 654-XL and the SU 654-EZ wheel?
A: The SU 654-XL is made from Polyurethane XL grade (97A Shore hardness) with a precision machined steel core, offering higher durability and abrasion resistance compared to Cushothane XL. Both are 5.000 inch by 3.625 inch, but the SU 654-XL is better for rough warehouse floors and high-abrasion environments. The XL material lasts longer but may provide less shock absorption than Cushothane.
Q: Does the SU 654-XL replace the SU 654-XL-A and SUS654-XL-SP part numbers?
A: The SU 654-XL supersedes and is equivalent to SU 654-XL-A and SUS654-XL-SP. These are the same wheel from the same manufacturer. The SU 654-XL is the current part number. If you have old inventory or need to cross-reference, use SU654-XL, SU 654-XL-A, or SUS654-XL-SP interchangeably. Always confirm bore diameter is 2.188 inches for your application.
Q: Is the SU 654-XL a press-fit wheel, and what installation method is required?
A: The SU 654-XL is a plain bore press-fit wheel with no tapered coupling or quick-change interface. Installation requires pressing the wheel onto a straight axle shaft. Use a hydraulic press or bearing press for proper fitment. Do not hammer or force the wheel, this can crack the bore or damage the steel core. The wheel should slide smoothly with light pressure and seat fully against the axle shoulder.
Q: What is the core material and bore construction for the SU 654-XL?
A: The SU 654-XL has a precision machined steel core with a 2.188 inch plain bore. The steel core provides structural strength and durability. The bore is toleranced to ISO fit standards for a reliable press-fit connection. The wheel is designed for straight axle mounting only, not for roller bearings or tapered bores.
Q: When should I use the SU 654-XL instead of other load wheel options?
A: Use the SU 654-XL in high-abrasion environments such as outdoor concrete pads, rough warehouses, or facilities with sharp debris on the floor. The XL polyurethane grade resists chunking and tearing better than softer compounds. If your truck operates on smooth indoor floors, a lower-durometer wheel may provide better ride quality. Evaluate your specific floor conditions before selecting wheel hardness.
Q: How long does the SU 654-XL typically last in service?
A: The SU 654-XL typically lasts 800 to 1500 operating hours depending on floor condition and load intensity. High-abrasion environments reduce lifespan to 800 hours. Indoor smooth floors extend service life to 1500 hours or more. Inspect the wheel quarterly for flat spots, tread separation, or discoloration indicating overheat. Replace immediately if tread is worn to less than 50 percent of original depth.
