Frequently Asked Questions
Q: What are the exact dimensions of the GW 446-A1 poly load wheel assembly?
A: The GW 446-A1 wheel assembly measures 3.250 inch diameter by 4.500 inch width, which equals 82.55mm by 114.30mm. It has a 17mm bearing bore (0.669 inch bore ID). Verify these measurements against your lift truck specification before ordering to ensure compatibility.
Q: Can the GW 446-A1 wheel fit on a 15mm or 20mm bearing shaft?
A: No. The GW 446-A1 is designed exclusively for 17mm bore diameter shafts. Do not attempt to force-fit this wheel onto different bearing sizes, as this will cause improper load distribution, bearing damage, and safety hazards. Verify your shaft diameter before ordering.
Q: What is the maximum load rating for the GW 446-A1 wheel?
A: Load capacity depends on the bearing grade, hydraulic system pressure rating, and total lift truck configuration. The GW 446-A1 specifications do not stand alone. Consult your lift truck manual or parts documentation for the complete load capacity and duty cycle ratings.
Q: How should I install the GW 446-A1 wheel assembly?
A: Do not pound or force the wheel onto the shaft. Slide the assembly straight onto the 17mm bearing shaft until the wheel seating is fully seated against the wheel hub. If resistance is high, check bearing bore and shaft diameter for damage or contamination. Use appropriate bearing spacers and retaining hardware per the lift truck assembly manual.
Q: What maintenance does the GW 446-A1 wheel require?
A: Inspect wheels monthly for wear, flat spots, and cracks. Rotate wheels periodically to distribute wear evenly. Ensure the bearing shaft is free from rust and debris. Do not lubricate the polyurethane wheel itself. Check bearing play and replace bearings if they exhibit excessive side-to-side movement.
