Frequently Asked Questions
Q: What makes the GW 128 different from a standard replacement wheel?
A: The GW 128 includes a pre-installed axle and sealed ball bearings, making it a complete wheel assembly. Unlike separate wheel and bearing components, the GW 128 arrives ready to bolt on without additional assembly or bearing installation. This reduces installation time and ensures consistent bearing preload and alignment.
Q: Which manual pallet jack models use the GW 128 assembly?
A: The GW 128 is designed for standard manual pallet jacks and trucks using industry-standard load wheel configurations. The high-impact thermoplastic polymer or polypropylene core combined with the polyurethane tread provides durability across concrete, asphalt, and smooth warehouse floors. Confirm your truck model requires the GW 128 by checking your documentation or the existing wheel markings.
Q: How do I diagnose seal failure or bearing wear in the GW 128?
A: Sealed bearings in the GW 128 do not require lubrication and should operate quietly. If you hear grinding, squeaking, or clicking noises when rotating the wheel, the seal may be compromised and water or contaminants have reached the bearing. Excessive play in the wheel (more than 0.25 inch of vertical movement) indicates bearing degradation. Once a seal fails, replace the entire GW 128 assembly; sealed bearings cannot be serviced in the field.
Q: What is the installation procedure for the GW 128 pre-assembled wheel?
A: Secure the pallet jack fork tips in a level position. Remove the old wheel and axle assembly from the fork tip mounting bracket. Position the GW 128 pre-installed axle into the mounting holes and bolt it securely. Ensure the assembly is tight to prevent axle movement during operation. Rotate the wheel by hand to verify smooth, noise-free operation. No additional bearing adjustment or lubrication is required upon installation.
Q: What is the expected lifespan and maintenance for the GW 128?
A: The GW 128 is designed for heavy-duty, smooth, low-noise operation with an expected service life of 3 to 5 years under normal warehouse conditions. The sealed bearings require no lubrication. Inspect the polyurethane tread monthly for cracks, flat spots, or chunks. Wipe wheels clean regularly to prevent debris buildup. Do not attempt to repack or service the sealed bearings. Replace the entire assembly when bearing noise develops or tread is less than 0.25 inch thick.
