Frequently Asked Questions
Q: What does XL mean in SU 529-XL?
A: XL indicates the Cushothane XL polyurethane compound, a premium grade formulation that resists wear and hardening better than standard polyurethane. SU 529-XL wheels last 30 to 40 percent longer than non-XL variants on the same truck and duty cycle.
Q: Is SU 529-XL compatible with both hydraulic and electric pallet jacks?
A: SU 529-XL is designed for electric pallet trucks. Hydraulic walkie models use different wheel sizes and bore configurations. Verify your truck nameplate before ordering. Mixing wheel types can cause load imbalance and steering failure.
Q: How do I identify if my truck currently uses SU 529-XL or a standard SU 529?
A: Check your truck parts manual or original wheel marking. Many trucks do not label wheel grade at purchase. The only way to confirm is to inspect the wheel compound for hardness or contact the truck OEM with your truck serial number. Do not assume all wheels on used equipment are the same grade.
Q: Can I mix SU 529-XL wheels with standard SU 529 wheels on the same truck?
A: Not recommended. Mixing wheel materials and wear rates creates steering imbalance and uneven load distribution. Replace all load wheels at the same time to maintain consistent rolling resistance and truck control.
Q: What is the cost difference between SU 529-XL and SU 529, and is it worth it?
A: SU 529-XL typically costs 15 to 25 percent more per wheel. In high-use warehouse environments (5000+ load cycles per month), the extended lifespan pays for itself within 12 months due to reduced downtime and replacement labor. For light-duty use, standard SU 529 is usually sufficient.
