Frequently Asked Questions
Q: What is included in the SU 9871-XL-A assembly?
A: The SU 9871-XL-A is a complete wheel assembly with pre-installed sealed bearings, spacers, and the poly XL 97A load wheel. It arrives field-ready for direct installation into Superior pallet jack wheel positions. No additional bearing or spacer installation is required.
Q: What is the XL3 polymer-to-steel bonding technology?
A: XL3 is a hybrid mechanical and chemical bonding process that fuses the poly compound to a specially prepared steel core. This technology prevents delamination and wheel separation even under heavy shock loads. The bonding is permanent and cannot be reversed or re-bonded after installation.
Q: Can the SU 9871-XL-A be used in dual or triple wheel configurations?
A: Yes. The SU 9871-XL-A is designed for compatibility in dual or triple wheel assemblies on Superior pallet jacks. The bore diameter and spacer sizing match OEM specifications for multiple wheel setups. Install exactly one assembly per wheel position following the truck manual.
Q: How do I install the SU 9871-XL-A on my Superior pallet jack?
A: Lift the truck fully on stands and remove the axle nut from the wheel position. Slide the axle through the bore of the SU 9871-XL-A assembly and secure with the original axle nut. Do not disassemble the bearing cartridge or spacers. Spin the wheel by hand to confirm free rotation before lowering the truck.
Q: What is the load capacity of the SU 9871-XL-A assembly?
A: Load capacity varies based on whether the assembly is used in a single, dual, or triple wheel setup. The poly XL 97A compound delivers high load carrying capacity under sustained load. Refer to your Superior pallet jack manual or contact the manufacturer to determine maximum safe load for your specific configuration.
Q: What maintenance is required for sealed bearings in the SU 9871-XL-A?
A: Sealed bearings require no lubrication or maintenance during service life. Do not attempt to grease or re-seal the bearings after installation. Inspect monthly for excessive side-to-side play or grinding sounds. If bearing damage is suspected, the entire assembly must be replaced as sealed bearings cannot be serviced in the field.
