Frequently Asked Questions
Q: What are the dimensions of the SU S9111-XL-A load wheel?
A: The SU S9111-XL-A measures 6.000 inches outer diameter by 2.750 inches tread width. The inner bore diameter is sized for standard 6203-2RS bearings. This larger diameter makes it suitable for high-speed warehouse and aisle applications where reduced rolling resistance is needed.
Q: Which electric pallet jack models does the SU S9111-XL-A fit?
A: The SU S9111-XL-A is compatible with electric lift truck load wheel assemblies that use 6-inch diameter wheels with 6203-2RS bearing specifications. Verify the bearing ID and hub width against your equipment documentation before ordering. No published OEM cross-references exist for this part number.
Q: What material is the SU S9111-XL-A wheel made from?
A: The SU S9111-XL-A features industrial-grade polyurethane tread bonded to a steel hub using XL3 polyurethane-to-steel bonding technology. The XL compound provides high tear resistance and durability under heavy warehouse duty cycles with extended load wheel life.
Q: How do I install the SU S9111-XL-A on my electric lift truck?
A: Remove the axle bolt and slide off the existing wheel assembly. Press the SU S9111-XL-A onto the axle shaft, ensuring the bearings seat fully into the hub bore. Verify the wheel rotates freely without binding. Reinstall and torque the axle bolt per your equipment manufacturer specifications. Do not reuse damaged bearings.
Q: What is the expected service life of the SU S9111-XL-A?
A: Service life depends on load cycles, surface conditions, and maintenance. High-traction XL compounds typically deliver 18 to 36 months in continuous warehouse duty. Inspect wheels quarterly for tread wear, cracks, or bearing damage. Replace immediately if the polyurethane layer delaminates from the steel hub.
