Frequently Asked Questions
Q: Is SU 529-A a plug-and-play replacement wheel assembly?
A: SU 529-A includes the polyurethane tread and machined steel hub pre-assembled. You must still install bearings and seals on the bore, then press the entire assembly onto your truck axle. It is not a true plug-and-play part; you need a press and bearing kit.
Q: What bearing size and type does SU 529-A require?
A: The bore outside diameter is 2.0467 inches (52mm metric equivalent). Bearing selection depends on your truck OEM. Most Yale and Hyster electric pallet trucks use 52mm tapered roller bearings or deep-groove ball bearings. Verify your truck manual or old bearing marking before ordering replacement bearings.
Q: How do I know if SU 529-A fits my truck instead of SU 529-XL-A?
A: Measure your existing wheel width side-to-side. SU 529-A and SU 529-XL-A both are 6 inches wide. Both fit the same trucks. The difference is in material grade (XL indicates a premium compound). If replacement wheels are wearing fast, upgrade to XL for longer lifespan.
Q: Can I re-use the bearings and seals from my old SU 529-A wheel?
A: Not recommended. Remove bearings from the old hub before disposing of the wheel. If bearings show rust, pitting, or play, replace them. Reusing worn bearings will cause misalignment and premature wear on the new assembly. New seal kits are inexpensive and strongly advised.
Q: What is the pressing force needed to install SU 529-A on an axle?
A: Use a hydraulic press with 10 to 20 tons of force, applied evenly to the bore. Do not use a hammer or arbor press. Uneven force will crack the steel hub or bend the axle. A shop press ensures straight installation and prevents binding.
