Frequently Asked Questions
Q: What is the load capacity rating for the SU S530-A wheel?
A: The SU S530-A is rated for use on electric lift trucks and pallet jacks with standard duty cycles. Load capacity depends on total assembly (typically 2500-3000 lbs per wheel on a 4-wheel configuration). Do not exceed the manufacturers rated capacity for your specific lift truck model. Always verify your trucks specifications before installation.
Q: Is the SU S530-A compatible with my reach truck or only pallet jacks?
A: The SU S530-A works on both electric pallet jacks and reach trucks that use 3.25 inch diameter load wheels with 1.875 inch width. The 1.875 inch width makes it suitable for single-wheel applications or side-by-side mounting. Check your trucks manual for the exact bore diameter and mounting configuration before purchase to ensure proper fit.
Q: What is the difference between SU S530-A and SU S530-XL?
A: The SU S530-A uses Cushothane XL material while the SU S530-XL features a steel core with high-durometer polyurethane tread designed for heavy-duty, high-cycle warehouse environments. Both are 3.25 inch by 1.875 inch dimensions. The S530-XL provides better durability for intense use but costs more. For standard duty use, the S530-A performs adequately.
Q: How do I remove and replace the SU S530-A wheel on my lift truck?
A: Lower the truck to ground level fully. Locate the axle pin or bolt holding the wheel (typically on the frame side). Remove the pin or unbolt the assembly. Slide the wheel off the axle shaft. Install the new SU S530-A by reversing the process, ensuring the wheel is seated fully and the pin or bolt is secured tightly. Do not operate the truck until all wheels are properly installed.
Q: What causes premature wear on the SU S530-A wheel?
A: Excessive use on rough outdoor surfaces, overloading beyond the trucks rated capacity, lack of lubrication on the bore, and prolonged exposure to oil or chemical spills accelerates wear. The Cushothane XL material is rated for indoor and light outdoor use. If your wheel shows chunking, flat spots, or cracks, replace it immediately to prevent steering problems and potential jack failure.
Q: Does the SU S530-A require any maintenance after installation?
A: Inspect the wheel monthly for cracks, flat spots, or debris buildup. Clean off any chemical residue or oil spills promptly as these degrade polyurethane. Lubricate the bore and axle with a light machine oil if the wheel is not sealed. Replace the wheel when tread depth becomes uneven or the wheel begins to rock on the axle. Expected lifespan is 2-4 years depending on use intensity.
