3 3/8 X 3.97 Load Wheel
Frequently Asked Questions
Q: What electric lift truck models use the SU 524 wheel?
A: The SU 524 measures 3 3/8 inches diameter by 3.97 inches width. This is a specialty load wheel size used on compact and narrow-aisle electric pallet jacks, walk-behind stackers, and order-picking trucks. Verify compatibility by measuring your current wheel diameter and width against these specifications. Check your truck manual for the SU 524 part number reference before ordering.
Q: Is the SU 524 suitable for high-capacity applications?
A: No. The SU 524 is a light-to-medium duty wheel intended for trucks rated between 2000 and 3500 lbs load capacity. The small 3 3/8 inch diameter limits load per wheel to approximately 1500-1750 lbs. For higher-capacity trucks or rough-surface operations, upgrade to larger diameter wheels like the SU 487-XL (8 x 2.5) or SU 459-XL-A (6 x 3).
Q: What is the bore and hub configuration of the SU 524?
A: Exact bore diameter, bore depth, hub width, and bearing type specifications for the SU 524 are not provided in standard catalogs due to its specialty size. Before ordering replacement wheels, remove your current SU 524 wheel from the truck and measure the bore inside diameter, bore outside diameter, bore depth, and hub width. Provide these measurements to your supplier to ensure the replacement matches your specific truck axle configuration.
Q: How often should I replace the SU 524 wheel?
A: Replace the SU 524 every 1000-2000 operating hours or when tread wear reaches 0.1875 inches. Because this wheel is small and operates on light-duty trucks, it experiences higher rotational speed and accelerated wear compared to larger wheels. Inspect every month for cracks, tread separation, or worn bearing play by spinning the wheel and listening for grinding noise.
