Load Wheel Assembly
Frequently Asked Questions
Q: Is the SU S835-A compatible with newer electric pallet truck models?
A: The SU S835-A is a legacy load wheel assembly. Cross-reference your truck model and serial range before ordering. If your truck originally shipped with SU S835-A, it will fit. For upgrades to modern electric lift trucks, check if the bearing bore and hub diameter match current specifications. Many newer models use SU S850 or SU S850-XL instead.
Q: What is the rated load capacity of the SU S835-A?
A: Load capacity specifications for the SU S835-A vary by production batch and application. Verify the rated load against your truck nameplate. Do not exceed the lower of the wheel rating or truck maximum load capacity. Contact the OEM with your truck serial number for exact specs.
Q: Can I replace SU S835-A wheels with SU S850 wheels?
A: Not without verification. The SU S850 has different diameter and load characteristics. Check that the bearing bore size, hub diameter, and axle fit match exactly. Mixing wheel types on the same truck can cause uneven wear and instability. Always replace all four wheels as a set with the same part number.
Q: How do I diagnose if SU S835-A wheels need replacement?
A: Replace wheels if you observe flat spots, chunks missing from the tread, or cracks in the polyurethane. Check for excessive noise or resistance during manual push tests. Inspect the bearing by spinning the wheel by hand; it should turn freely with minimal wobble. If the wheel locks or grinds, the bearing seal is failed and the wheel assembly must be replaced.
Q: What maintenance does the SU S835-A require?
A: Sealed ball bearings in the SU S835-A are maintenance-free. Weekly visual inspection for tread damage or foreign objects is sufficient. Do not attempt to lubricate or disassemble sealed bearings. Clean debris from the tread with a dry cloth. If bearing noise develops, replace the entire wheel assembly; sealed bearings cannot be serviced.
Q: What is the typical lifespan of the SU S835-A wheel?
A: Lifespan depends on usage intensity and load profiles. In standard warehouse duty, expect 2 to 4 years before tread wear becomes significant. High-cycle operations or outdoor use may reduce lifespan to 12 to 24 months. Replace proactively when tread depth approaches 0.5 inches or visual damage is visible.
