Frequently Asked Questions
Q: What does the -A designation mean for the SU S532-A wheel assembly?
A: The -A designation indicates this is a complete wheel assembly that may include additional components such as the hub, bearing preload, or installation fixtures compared to the base S532 wheel. Verify your purchase order specifies the complete assembly to ensure you receive all necessary mounting components. If only the wheel core is needed, confirm the part number does not include the -A designation.
Q: Does the SU S532-A wheel assembly come pre-assembled or do I need to install bearings?
A: The SU S532-A is supplied as a complete wheel assembly ready for installation. Do not disassemble or attempt to replace bearings unless your truck specification requires bearing maintenance. If the wheel develops a grinding sound or the axle becomes difficult to turn, the bearings may need lubrication or replacement. Consult a qualified technician for internal wheel service rather than attempting repairs yourself.
Q: What is the bore depth and bore outside diameter for the SU S532-A?
A: The SU S532-A has a bore depth of 0.591 inches and a bore outside diameter of 2.0467 inches. The inside diameter is 1.938 inches. These specifications ensure compatibility with standard 3.25 inch pallet jack and reach truck axles. Verify these dimensions match your trucks axle specifications before purchase. Incorrect bore sizing will prevent proper wheel installation or cause the wheel to be loose on the axle.
Q: How do I install the SU S532-A on my lift truck?
A: Lower the truck fully to the ground. Locate the axle pin or mounting bolts on the frame. Remove the old wheel assembly completely. Inspect the axle shaft for corrosion or damage and clean it if needed. Slide the SU S532-A onto the axle shaft, ensuring it seats fully and the bore is centered. Install and tighten the axle pin or bolts securely. Do not operate the truck until all four wheels are properly installed and secured.
Q: What routine maintenance is required for the SU S532-A wheel assembly?
A: Inspect the wheel weekly for cracks, flat spots, or debris wrapped around the axle. Clean off oil spills or chemical residue promptly as these degrade polyurethane. If the wheel is not sealed, lubricate the bore and axle monthly with light machine oil. Rotate wheels (front to back or side-to-side) every 6 months if possible to promote even wear. Expected service life is 3-5 years under normal warehouse use.
Q: Can the SU S532-A wheel be repaired if the polyurethane is damaged?
A: No. Wheel damage cannot be safely repaired. Patched or glued wheels create uneven surfaces that cause steering problems and brake failure risk. If the wheel has cracks, missing chunks, flat spots, or the bore is damaged, replace the entire SU S532-A assembly. Do not attempt repairs. Always use new replacement wheels to maintain safe truck operation and extend the life of your lift truck.
