Frequently Asked Questions
Q: What is the load capacity for the SU S4001 poly load wheel, and what models does it fit?
A: The SU S4001 is a 2.750 inch (69.85mm) diameter by 2.000 inch (50.80mm) width poly load wheel with a 95A durometer rating. It fits most standard pallet jacks, hand trucks, and low-profile lift equipment with a 1.25 inch inside diameter bore. Always verify the bearing housing bore diameter (1.4562 inch) before installation to ensure proper fit. Maximum load capacity depends on your equipment model and number of wheels used—verify with your equipment documentation.
Q: How do I know if my SU S4001 load wheel needs replacement?
A: Replace the SU S4001 when you notice flat spots, cracks, chunks missing from the tread, or uneven wear patterns. If the wheel produces squeaking or grinding sounds during operation or the jack does not roll smoothly, inspect the wheel for damage or debris lodged in the bore. If the wheel diameter measures less than 2.5 inches or the poly material is visibly compressed or deformed, replacement is necessary. Worn wheels reduce load capacity and create safety hazards.
Q: What is the bore depth and bore outside diameter for the SU S4001, and does it require a specific axle size?
A: The SU S4001 has a bore depth of 0.472 inches and a bore outside diameter of 1.4562 inches. The inside diameter is 1.25 inches. You need an axle with a 1.25 inch diameter to fit this wheel properly. Verify that your existing axle matches these dimensions before ordering. Incorrect axle sizing will cause the wheel to wobble, misalign, or fall off during operation.
Q: Is the SU S4001 wheel compatible with the SU S4001-A assembly, and when should I use the assembly instead?
A: The SU S4001 is the wheel only, while the SU S4001-A is a complete wheel assembly that includes the wheel pre-mounted on a shaft or hub. Order the SU S4001 if you are replacing just the wheel on existing hardware. Order the SU S4001-A if you need a ready-to-install assembly or if your current axle or bearing assembly is damaged and needs replacement. Both have identical wheel dimensions and 95A durometer specifications.
Q: What maintenance is required to extend the life of the SU S4001 load wheel?
A: Inspect the SU S4001 wheel weekly for cracks, flat spots, or debris stuck in the bore or tread. Clean the wheel and bore with a dry cloth to remove dirt and grease that can cause premature wear. Lubricate the axle bearing per your equipment manual—do not over-lubricate, as excess grease attracts debris. Rotate the wheel by hand to confirm it spins freely without grinding or resistance. Store the jack on a flat surface indoors to prevent flat-spotting when not in use for extended periods.
