Frequently Asked Questions
Q: Does SU S459-A include bearings and what is the installation process?
A: Yes, SU S459-A is a complete wheel assembly with bearings installed. Installation is plug-and-play: slide the assembly onto the axle shaft, align any key or pin holes, and secure with the retaining bolt or snap ring. Do not disassemble the bearings unless bearing replacement is necessary. Verify axle shaft length does not exceed 0.78 inches of the inside bore depth.
Q: What tools do I need to install the SU S459-A wheel assembly?
A: Installation requires a socket wrench or open-end wrench for the axle bolt, and possibly a rubber mallet if the wheel is tight on the shaft. Do not use a hammer or impact driver on the wheel rim. If the wheel will not slide on the axle, inspect the axle for debris, rust, or damage. Never force a wheel onto a damaged axle.
Q: Can I replace just the wheel and keep the existing bearings from a worn SU S459-A assembly?
A: Only if the existing bearings are in good condition. Inspect bearings by spinning the axle by hand. There should be no noise, grinding, or excessive play. If bearings are worn or damaged, replace the entire assembly with a new SU S459-A. Reusing worn bearings will cause premature failure of the new wheel.
Q: What is the rated load capacity of SU S459-A?
A: Load capacity is determined by the jack frame and bearing specification, not by the wheel itself. SU S459-A wheels are engineered for standard warehouse electric lift trucks rated between 2,500 and 6,000 pound capacity. Verify your jack capacity plate before operating. Do not exceed the manufacturer rated load.
Q: How do I diagnose if SU S459-A bearings have failed?
A: Symptoms of bearing failure include grinding noise when rolling, the wheel heating up, excessive lateral play on the axle, or the wheel suddenly locking up. If you hear grinding or feel excessive play, stop using the jack immediately. Do not attempt to repair bearings. Replace the entire SU S459-A assembly to prevent frame damage or injury.
Q: What is the storage and shelf life of SU S459-A?
A: SU S459-A wheels maintain quality for 3-5 years when stored in a dry, temperature-controlled environment away from direct sunlight and oils. Store wheels vertically or on their side to prevent flat-spotting. Do not store outdoors or in damp conditions. Before installation, inspect the tread and bearing operation even if the wheel is new in stock.
