Frequently Asked Questions
Q: What does the EZ designation mean on the SU S673-EZ wheel?
A: EZ stands for Easy-change or tool-free design. The SU S673-EZ features a quick-release collar that does not require a cotter pin or wrench. You can slide the wheel on or off by hand by loosening the compression collar, making field replacement faster.
Q: Is SU S673-EZ a complete assembly or wheel only?
A: SU S673-EZ is a wheel only. You must transfer your sealed bearing cartridge, spacer, and quick-release collar from the old wheel. If you need a ready-to-install unit with new bearings, order SU S673-EZ-A (complete assembly).
Q: What load capacity does the SU S673-EZ wheel handle?
A: SU S673-EZ is rated for 4200 pounds per wheel, same as standard SU S673. Tire is 8 inch diameter, 6.5 inch width, polyurethane material for indoor concrete floors. Do not overload or use on outdoor surfaces.
Q: Can I swap the quick-release collar between SU S673 and SU S673-EZ?
A: No. The SU S673-EZ collar is engineered for tool-free operation and does not fit standard SU S673 wheels. Mixing collars causes improper wheel seating and safety hazards. Keep collars matched to their wheel type.
Q: How do I diagnose bearing wear on the SU S673-EZ?
A: Loosen the compression collar slightly, spin the wheel by hand, and listen for grinding or squealing. A healthy bearing spins freely for 10-15 seconds. If you hear noise or feel drag, the bearing cartridge is worn and must be replaced. A worn bearing also causes the wheel to wobble side to side.
