Frequently Asked Questions
Q: What does the XL designation mean on the SU 459-XL wheel?
A: The XL designation typically indicates extended life or upgraded material composition. The SU 459-XL is made from Cushothane XL, which is a premium elastomer formulation designed for longer service life and better performance under heavy industrial duty than standard Cushothane. XL material resists heat, oils, and abrasion better than conventional wheel materials.
Q: Are the SU 459-XL, SU 459-A, and SU 459 wheels interchangeable on the same lift truck?
A: Yes, all three wheels have identical dimensions: 6 inches outer diameter by 3 inches width. The bore specifications are the same. However, the materials differ. The SU 459 and SU 459-A use standard Cushothane while the SU 459-XL uses Cushothane XL. You can substitute the SU 459-XL wheel for either model if the bearing or hub requirements match, but verify bore compatibility before ordering.
Q: Should I upgrade from SU 459 to SU 459-XL wheels if my truck operates in a hot or oily environment?
A: Yes, the SU 459-XL is a better choice for hot, oily, or chemically aggressive environments. Cushothane XL resists degradation from heat and petroleum products better than standard Cushothane. If your truck operates in a warehouse with grease on the floor or near machinery that generates heat, the SU 459-XL wheels will last longer and provide better traction.
Q: What is the load capacity difference between the SU 459-XL and standard SU 459 wheels?
A: Load capacity is not published for either the SU 459 or SU 459-XL wheels. Both are designed as load wheels for the same lift truck models, so they likely have the same load rating. The upgrade from standard to XL material provides better durability and longer service life, not higher load capacity.
Q: How long will SU 459-XL wheels last compared to standard SU 459 wheels?
A: The SU 459-XL wheels typically provide 25 to 40 percent longer service life than standard SU 459 wheels under identical operating conditions. In normal industrial use, expect 24 to 36 months from SU 459-XL wheels versus 18 to 24 months from standard wheels. Heavy industrial or chemical environments favor the XL material even more due to superior resistance to degradation.
