Frequently Asked Questions
Q: What are the key specifications of the SU S234 load wheel?
A: SU S234 is a 4 inch diameter by 2.75 inch tread width load wheel with a 47/28 sealed ball bearing set, machined steel hub, and high-performance polyurethane tread rated Shore A 95 hardness. It uses a 20 mm axle bore with press fit installation. Manufacturer part number is SU S234-SP.
Q: Is SU S234 compatible with a 20 mm axle shaft, or does it require a different bore size?
A: SU S234 is manufactured for 20 mm axle shafts with press fit installation. Do not attempt to install on 16 mm, 25 mm, or other axle diameters without machining the hub bore. Verify your lift truck axle diameter before ordering.
Q: How do I identify if SU S234 has sealed or open bearings?
A: SU S234 uses sealed ball bearings (47/28 precision grade), which means the bearing is completely enclosed and pre-lubricated. Sealed bearings cannot be regreased and should not be exposed to moisture. If water entry occurs, replace the wheel assembly immediately.
Q: What is the load capacity per wheel for SU S234, and how is it calculated?
A: Load capacity depends on the truck model and bearing rating. The 47/28 sealed ball bearings in SU S234 support heavy-duty industrial pallet jacks rated 4,000 to 6,500 pounds total. Divide truck capacity by the number of wheels on the ground to determine per-wheel load. Consult the truck manual for exact specifications.
Q: Can I use SU S234 wheels on outdoor or wet warehouse floors?
A: SU S234 polyurethane treads are abrasion-resistant but absorb moisture over time. Sealed bearings reduce water intrusion risk, but prolonged outdoor use or water submersion can degrade the tread and cause corrosion inside seals. Wipe wheels dry after wet environment use. If wheels sit in standing water, replace them.
Q: What is the installation method for SU S234, and does it require a press machine?
A: SU S234 uses press fit installation onto the 20 mm axle bore. A hydraulic press or bearing press is required for proper seating. Do not hammer the wheel onto the axle, as impact can damage bearings. Press the wheel slowly onto the axle until the hub fully seats against the retaining shoulder.
