Frequently Asked Questions
Q: What are the exact dimensions of the SU 248-XL load wheel?
A: The SU 248-XL has an outside diameter of 3.25 inches (82.55 mm), a width of 6.0 inches (152.40 mm), an inside bore diameter of 1.875 inches, a bore depth of 0.912 inches, a bore outside diameter of 1.9795 inches, and a hub width of 6.0 inches. The tire material is Cushothane EZ elastomer. Verify all dimensions against your truck manual before purchase to ensure proper fit in the load wheel pocket.
Q: Is the SU 248-XL compatible with standard 1-7/8 inch axles?
A: The SU 248-XL has a bore inside diameter of 1.875 inches, which matches standard 1-7/8 inch axles. However, verify that the bore depth (0.912 inches) and the bearing pocket design on your truck axle are correct. Measure your existing wheel bore before ordering to confirm compatibility. A bore that is too shallow will cause the wheel to rock; too deep may prevent proper seating.
Q: Why is the SU 248-XL called an XL wheel and what does that mean?
A: The XL designation typically indicates the SU 248-XL is a larger-capacity or heavy-duty variant within the Superior product line. The 3.25 inch diameter and 6.0 inch width are suitable for medium-duty industrial electric lift trucks. XL often implies enhanced bearing capacity or load rating compared to standard or compact models. Confirm your load requirement matches this wheel before purchasing; undersizing will cause premature wear.
Q: What is the load rating per wheel for the SU 248-XL?
A: Load rating depends on the bearing type, material, and truck configuration. The SU 248-XL with Cushothane EZ tire typically supports 2000 to 3500 lbs per wheel for industrial lift truck duty. Consult the Superior product datasheet for exact load ratings. Do not exceed the per-wheel limit; overloading causes bearing premature failure, wheel deformation, and potential truck instability.
Q: How does Cushothane EZ material compare to other elastomer tire options?
A: Cushothane EZ is a polyurethane elastomer designed for smooth warehouse floors and light outdoor use. It offers good load-carrying capacity and moderate wear resistance. Compared to solid rubber, it provides better shock absorption and less floor marking. Compared to pneumatic tires, it is lower maintenance and puncture-proof. Choose Cushothane EZ for typical warehouse operations; use alternative tire materials for outdoor, harsh, or chemical environments.
Q: How do I install the SU 248-XL load wheel on my truck?
A: Remove the axle nut and lock washer with a socket wrench. Use a bearing puller or hydraulic press to remove the old wheel from the axle. Slide the SU 248-XL bore onto the axle shaft and press or drive it fully onto the axle until the hub shoulder seats against the axle shoulder. Install the lock washer and torque the axle nut to 40 to 60 ft-lbs (verify your truck manual). Test the wheel for free rotation and proper seating before operating the truck.
