Frequently Asked Questions
Q: Is GW 9433-A cross-compatible with GP 9433-A and GP9433-A?
A: Yes. GW 9433-A is cross-referenced as GP 9433-A and GP9433-A. All three part numbers represent the same 3.000 x 3.500 inch 95A polyurethane wheel on steel core. Order whichever part number your system recognizes. Bearing ID is 19 mm for all variants.
Q: How often should I replace the GW 9433-A caster wheel?
A: Replace when the 95A polyurethane tread shows flat wear spots, cracks, or missing material, or when bearing rotation becomes rough or noisy. Typical lifespan is 12 to 24 months depending on daily hours and load. Inspect all casters quarterly. Replace all four wheels as a set to maintain balanced truck handling.
Q: Can I replace just one GW 9433-A wheel or must I replace all four?
A: Best practice is to replace all four wheels as a matched set. If you must replace a single wheel due to emergency damage, verify the remaining three wheels are in good condition. Mismatched wheel wear will cause the truck to pull to one side and increase vibration. Plan to replace remaining casters at the next scheduled maintenance cycle.
Q: Is the GW 9433-A bearing sealed or open, and does it require grease?
A: The GW 9433-A features a sealed bearing assembly that is pre-lubricated and does not require maintenance or additional grease. The sealed design protects against contamination. If bearing noise develops, the bearing has failed and the wheel assembly must be replaced as a unit.
