Frequently Asked Questions
Q: What is the main difference between GW 641-A and GW 641-A-20MM?
A: The only difference is the bearing ID. The GW 641-A has a 25mm bore, while the GW 641-A-20MM has a 20mm bore. Both have identical 4.000 inch diameter and 2.875 inch width. Choose based on your lift truck shaft diameter. Using the wrong bore size causes wobbling and accelerated bearing failure.
Q: How do I verify if my truck needs 20mm or 25mm bearing ID wheels?
A: Measure the wheel shaft diameter with calipers. 20mm equals 0.787 inch, 25mm equals 0.984 inch. Check your lift truck manual for the wheel specification, or contact your truck OEM with the serial number. Do not guess or force a wheel onto a shaft as this causes permanent damage to both the wheel and shaft.
Q: Can the GW 641-A-20MM be used on electric or manual pallet jacks?
A: The GW 641-A-20MM is designed for electric lift trucks with 20mm shafts. Compatibility depends on your specific truck model and shaft configuration. Consult your truck documentation or contact the manufacturer to confirm fitment before purchasing.
Q: What load capacity does the GW 641-A-20MM support?
A: Load capacity depends on the truck model and configuration. The Durarun 95A polyurethane tread material supports typical electric lift truck loads, but do not exceed your trucks rated capacity. Exceeding rated load causes premature polyurethane degradation and bearing failure.
Q: Is regular maintenance required for the GW 641-A-20MM wheel?
A: Inspect wheels monthly for debris stuck in the tread and clean as needed. Check bearing rotation periodically to ensure smooth operation. Lubrication is not required for sealed bearings. Replace the wheel when tread becomes hard, flat-spotted, or cracked.
Q: What tools and skills are needed to replace the GW 641-A-20MM wheel?
A: Replacement requires a bearing puller, shop press, and basic mechanical skills. Remove the wheel clip, press off the old wheel using a puller, and press the new GW 641-A-20MM wheel onto the shaft. This is not a field-serviceable operation. Use a professional mechanic or technician if you lack experience with wheel presses.
