Frequently Asked Questions
Q: What is the advantage of the GW 9433-A1 semi-pneumatic polyolefin wheel over the standard polyurethane GW 9433?
A: The GW 9433-A1 features a flat-free, semi-pneumatic polyolefin wheel that eliminates puncture risk and provides a smoother ride compared to the solid 95A polyurethane tread on GW 9433. The GW 9433-A1 absorbs impact better and reduces vibration, extending component lifespan. Use GW 9433-A1 on rough warehouse floors or outdoor terrain. Standard GW 9433 is suitable for smooth, climate-controlled environments.
Q: What is the load capacity of the GW 9433-A1 semi-pneumatic wheel?
A: The GW 9433-A1 is rated for 1200 lbs per wheel in typical industrial material handling duty. Total truck load capacity depends on the number of drive wheels and casters and your truck nameplate rating. Verify your specific truck OEM documentation before exceeding any published load limits. Overloading causes premature bearing failure.
Q: The GW 9433-A1 has a 17mm bearing ID while the standard GW 9433 uses 0.750 inch. Can I swap these?
A: No. The 17mm bearing ID on GW 9433-A1 is not compatible with trucks designed for the 0.750 inch bearing ID on GW 9433. Verify your truck axle bore diameter before ordering. Using an incompatible wheel will cause loose fitment or bearing binding. Check your truck service manual or contact the OEM to confirm which bearing size your model requires.
Q: Is the GW 9433-A1 flat-free wheel maintenance-free?
A: Yes. The flat-free, semi-pneumatic polyolefin design requires no air pressure, no tire rotation, and no puncture repair. Inspect quarterly for flat wear spots and loss of tread. Replace when the tread is worn smooth or the wheel develops flat spots under load. The bearing is sealed and maintenance-free.
Q: Can I upgrade from GW 9433 to GW 9433-A1 on my existing truck?
A: Only if your truck axle bore is 17mm. The GW 9433-A1 is physically identical in diameter and width to GW 9433 (3.000 x 3.500 inches), so ground clearance is not affected. However, bearing bore mismatch will prevent installation. Confirm bearing ID compatibility before attempting the upgrade. If your truck uses 0.750 inch bearings, you cannot use GW 9433-A1.
Q: What is the installation procedure for the GW 9433-A1?
A: Lift the truck and block wheels. Remove the axle fastener and slide out the worn wheel. Align the 17mm bearing bore with your truck axle and slide on the GW 9433-A1 wheel. Secure with the original fastener, tightened hand-snug plus one-quarter turn. Test rotation before lowering the truck. Do not overtighten the sealed bearing.
