Frequently Asked Questions
Q: What equipment does the SU 640-A load wheel fit?
A: The SU 640-A is a load wheel assembly designed for electric lift trucks and pallet jacks from major OEM brands including Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich. Verify the mounting bore and overall diameter match your equipment before ordering.
Q: How do I know if the SU 640-A needs replacement?
A: Replace the wheel when you observe flat spots, chunking or cracking in the tread, excessive side-to-side play around the bearing, or a rough grinding sound during operation. These symptoms indicate the wheel or bearing has failed and cannot be safely repaired.
Q: Can I replace just the wheel without changing the bearing?
A: It depends on whether the wheel is a press-fit or bolt-on assembly. If the bearing shows play or does not spin freely, replace the complete assembly. If only the wheel tread is damaged and the bearing is still smooth and tight, ask us about core-credit or remanufactured options.
Q: What is the typical lifespan of this load wheel?
A: Lifespan depends on load, floor conditions, and usage hours. In normal warehouse conditions, a load wheel typically lasts 12 to 24 months before tread wear or bearing failure becomes noticeable. Cold storage and rough floors accelerate wear.
