Frequently Asked Questions
Q: What is the SU 556-XL load wheel used for?
A: The SU 556-XL is a load wheel designed for electric lift trucks and pallet jacks. It functions as a support and load-bearing wheel to enable smooth movement of the lift truck under load.
Q: Can I replace an older wheel model with the SU 556-XL?
A: Check your truck model and serial range against our compatibility chart. The SU 556-XL fits specific electric lift truck models. If your truck currently uses a different SKU, measure the bore diameter, wheel diameter, and width to verify fitment before purchasing.
Q: Is the SU 556-XL a complete assembly or wheel only?
A: The SU 556-XL is the wheel component only. If you need the wheel already mounted on a hub assembly with bearings installed, order the SU 556-XL-A instead.
Q: How long does an SU 556-XL wheel typically last?
A: Lifespan depends on duty cycle and maintenance. In normal warehouse use, expect 3-5 years. Extend wheel life by keeping the truck on level floors, checking bearing clearance monthly, and replacing the wheel immediately if you notice flat spots, cracks, or grinding noise.
Q: What maintenance does the SU 556-XL require?
A: Inspect the wheel monthly for wear, flat spots, or material separation. If the truck pulls to one side, spin each wheel by hand to check for binding. Keep wheels clean of debris. If a wheel does not spin freely, the bearing may need replacement or adjustment; do not operate the truck.
