2.9 X 3.875 LOAD WHEEL, EZ
Frequently Asked Questions
Q: What are the exact dimensions of the SU S9124-EZ load wheel?
A: The SU S9124-EZ is 2.9 inches in diameter by 3.875 inches in width. This is a specialty size designed for narrow aisles and confined spaces. Before ordering, verify your truck frame has clearance for the 3.875 inch width and confirm the axle bore accepts the 2.9 inch diameter wheel.
Q: Is the SU S9124-EZ compatible with narrow-aisle electric pallet jacks?
A: The 2.9 X 3.875 dimension is typical for narrow-aisle or walkie pallet trucks. Verify your specific model and serial range against the application chart. If your truck originally had different wheel sizes, the SU S9124-EZ is not a direct replacement without frame modification. Always cross-reference the OEM part number.
Q: What causes premature wear on the SU S9124-EZ wheel?
A: The wider 3.875 inch profile is prone to edge wear if the truck steering is misaligned or if aggressive turning is performed at full load. Operating on uneven floors with the wide wheel creates stress at the tread edges. Worn caster or kingpin bearings also accelerate wear. Regular alignment checks extend wheel life by 50 percent.
Q: How do I install the SU S9124-EZ wheel on my narrow-aisle truck?
A: Installation is identical to standard wheels: remove the axle pin or bolt, slide the wheel assembly off, and install the new wheel. The EZ designation means simplified mounting. Do not force the wheel onto the axle; if resistance occurs, verify bore diameter and keyway alignment. Secure the axle pin fully and confirm the wheel rotates freely before use.
Q: What durometer polyurethane is recommended for the SU S9124-EZ?
A: The SU S9124-EZ is typically offered in 87A medium durometer for general warehouse use. This hardness balances traction on concrete with resistance to flat-spotting. If operating on polished concrete or very smooth floors, request 95A. For uneven or outdoor floors, consider 73A. Confirm availability with your supplier.
Q: Is bearing maintenance required for the SU S9124-EZ wheel?
A: Most wheels ship with sealed or shielded ball bearings packed with grease at the factory. No lubrication is needed. If grinding noise develops after 12 months, bearing wear may have begun. Do not add grease to sealed bearings. Replace the entire wheel assembly if noise persists after cleaning.
