Frequently Asked Questions
Q: What makes the GW 318 different from the GW 317, and which should I choose for my pallet truck?
A: The GW 318 is 8 x 2 inches, while the GW 317 is 7 x 2 inches. The GW 318 uses glass-filled nylon for exceptional durability and low rolling resistance, making it ideal for high-volume warehouse operations. If your pallet truck currently has an 8 inch diameter wheel, the GW 318 is the replacement. If it has a 7 inch wheel, the GW 317 is correct. Using the wrong size will cause poor steering and equipment damage.
Q: What is the bearing specification for the GW 318, and does it fit standard pallet jack axles?
A: The GW 318 features hardened steel bearing races and a 20mm (0.787 inch) bearing ID. This bore size is standard across most manual pallet jacks. Before purchasing, verify your equipment uses a 20mm axle shaft. If your shaft is 16mm or 25mm, the GW 318 will not fit. Measure the existing wheel axle bore with calipers or contact the equipment manufacturer to confirm specifications.
Q: Why does the GW 318 use glass-filled nylon instead of standard nylon?
A: Glass-filled nylon provides greater load capacity, reduced deflection, and lower rolling resistance compared to standard nylon. This means smoother operation, longer service life, and reduced wear on bearings even under sustained heavy loads. For warehouse applications where pallet trucks operate 8 or more hours daily, glass-filled nylon wheels are more cost-effective because they last longer and require fewer replacements than standard nylon.
Q: How do I know if the GW 318 bearing is damaged, and can it be replaced without replacing the entire wheel?
A: Symptoms of bearing failure include grinding noise when the wheel spins, excessive wobbling, rough rotation, or resistance when steering. To test, lift the pallet truck and spin the wheel by hand. It should rotate freely for 10 or more full turns. If it stops abruptly or makes noise, bearing failure has occurred. The hardened steel bearing races in the GW 318 are not field-replaceable. The entire assembly must be replaced.
Q: What is the installation procedure for the GW 318 on a warehouse pallet truck?
A: Support the equipment safely on a lift or jack. Remove fasteners using a wrench or socket matching your equipment (typically 1/2 inch or M12). Pull the old wheel straight off the axle shaft. Clean the axle shaft with a wire brush to remove corrosion or debris. Slide the GW 318 onto the 20mm axle shaft. Reinstall and tighten fasteners evenly in a criss-cross pattern to prevent binding. Test wheel rotation before returning equipment to service.
Q: What maintenance schedule should I follow for the GW 318 in high-volume warehouse use?
A: Inspect the GW 318 monthly under heavy daily use. Check for visible cracks, flat spots, or uneven wear on the glass-filled nylon surface. Verify the wheel rotates smoothly and does not wobble on the axle. Sealed bearings require no lubrication. If wear exceeds 1/4 inch depth or rotation becomes difficult, replace the assembly. Glass-filled nylon wheels typically last 3 to 7 years depending on load and frequency. Replace proactively before failure to avoid unexpected downtime.
