Frequently Asked Questions
Q: What equipment is the SU S934 load wheel designed for?
A: The SU S934 is a load wheel for pallet jacks, walkie stackers, and powered industrial trucks in the light to medium duty category. Verify your equipment nameplate and compare axle bore diameter and bolt pattern before purchase. The S934 is not compatible with all brands or models.
Q: How does the SU S934 compare to SU S928 and SU S922-XL in load capacity?
A: The S934 occupies a middle ground in load rating, typically between 2,500 and 3,500 lbs. The S922-XL handles higher loads, while the S928 is lighter duty. Do not mix wheel models on the same jack, as uneven load distribution can damage components.
Q: What are the symptoms of a failing SU S934 wheel?
A: Listen for grinding, squealing, or squeaking. Visually inspect for flat spots, radial cracks, or chunks missing from the tread. If the wheel does not spin freely by hand or wobbles side-to-side, the bearing or axle is damaged and replacement is required immediately.
Q: What is the step-by-step installation procedure for the SU S934?
A: Remove the cotter pin and lock nut from the axle. Slide the old wheel off. If it is stuck, use a bearing puller. Inspect the axle for straightness and corrosion. Wipe it clean, apply a thin layer of lithium grease, slide the new SU S934 on, reinstall the nut and tighten snugly, install the cotter pin, and verify smooth rotation.
Q: What is the recommended greasing schedule for the SU S934?
A: Grease the bearing every 500 to 750 operating hours under normal conditions, or monthly at minimum. In high-temperature or high-speed environments, reduce the interval to 300 to 400 hours. Use standard multipurpose lithium grease. Do not over-grease, which can overheat the bearing.
Q: How long will the SU S934 load wheel last in typical warehouse use?
A: Under standard duty conditions with proper maintenance, expect 2 to 3 years of service life. High-impact applications or inadequate greasing may reduce this to 12 to 18 months. Regular visual inspection and prompt bearing replacement extends overall jack life.
