Frequently Asked Questions
Q: What does the XL designation mean on the SU S348-XL wheel?
A: The XL designation indicates the wheel is made from Cushothane XL material, which is a premium polyurethane compound. XL means extra-load or extended-life capability. Cushothane XL is harder and more durable than standard polyurethane, providing better wear resistance and longer service life. It is ideal for high-traffic warehouse floors and environments with harsh chemicals or oils.
Q: Is SU S348-XL the same wheel as SU S348 and SU S348-A?
A: SU S348-XL has the same 3.25 x 5.75 inch dimensions and bore specifications as SU S348. The difference is material grade. SU S348-XL is the wheel component only, while SU S348-A is the complete assembly. If your equipment specification calls for Cushothane XL material, you must order SU S348-XL, not the standard S348. Substituting standard material will not meet specification.
Q: How do I verify that Cushothane XL is the correct material for my jack?
A: Check your original equipment manual or the old wheel itself for material marking. It should say Cushothane, Cushothane XL, polyurethane, or molded rubber. If the marking is not visible, contact the equipment manufacturer with your model and serial number. Do not guess. Using the wrong material can cause steering problems and premature wear if the truck frame geometry expects a specific durometer or grip profile.
Q: What is the load rating for the SU S348-XL wheel?
A: Load rating depends on your specific equipment and how many wheels support the load. The SU S348-XL is engineered for electric lift trucks with standard duty cycles. Do not exceed the nameplate capacity of your truck. Cushothane XL material does not increase load capacity but improves durability and floor performance. Check your equipment manual for maximum rated load.
Q: Why is Cushothane XL more expensive than standard polyurethane?
A: Cushothane XL costs more because it uses a harder, more durable polymer compound that resists wear, oil, and chemicals better than standard polyurethane. It maintains grip longer and requires replacement less frequently, reducing total cost of ownership despite higher initial price. In high-use warehouses with frequent wet cleaning or chemical exposure, Cushothane XL provides better value over a 3 to 5 year lifecycle.
Q: Can I replace just the SU S348-XL wheel if the bearing is still good?
A: Yes, if the bearing and hub are in good condition, you can replace only the wheel. This requires pressing the old wheel off the bearing hub and pressing the new SU S348-XL wheel onto the same hub. This is a specialized procedure requiring a hydraulic press and trained technician. If you are not equipped to do this, order the complete SU S348-A assembly instead. Improper wheel installation can cause wobbling or separation.
