Frequently Asked Questions
Q: Is SU 529 a complete wheel assembly or just the tread?
A: SU 529 is the polyurethane tread wheel component only. It does not include the steel hub or bearings. If you need a ready-to-install assembly, order SU 529-A or SU 529-XL-A instead.
Q: Can SU 529 be installed on a standard steel wheel hub from another manufacturer?
A: SU 529 fits any steel hub with a 1.938 inch inside diameter and 2.0467 inch bore outside diameter. Confirm your hub dimensions before pressing the wheel on. The 6 inch width means the hub must be exactly 6 inches wide to ensure even tread load.
Q: What is the maximum load rating for a pallet jack using SU 529 wheels?
A: Load capacity depends on the number of wheels and truck frame design, not the wheel alone. SU 529 is rated for standard electric pallet jacks (typically 4000 to 6000 pounds per truck). Check your truck nameplate for maximum load. Exceeding capacity will accelerate wear and cause premature failure.
Q: Does SU 529 require pressure testing or inflation?
A: No. SU 529 is a solid polyurethane wheel. It does not require inflation or tire pressure monitoring. This is a key advantage over pneumatic alternatives for indoor warehouse use; no flats or blowouts.
Q: How should I store SU 529 before installation?
A: Store in a cool, dry location away from direct sunlight and ozone-producing equipment (such as arc welders). Keep away from oils and solvents, which can soften Cushothane XL. Do not exceed 86 degrees Fahrenheit. Proper storage extends shelf life to 18 months or more.
