Frequently Asked Questions
Q: What is the bearing bore size for the GW 332 and how does it differ from GW 331?
A: The GW 332 uses a 0.75 inch (19.050mm) bearing bore, while the GW 331 uses 20mm (0.787 inch). These are not interchangeable. A 0.75 inch axle will not fit a 20mm bore and vice versa. Always verify your axle diameter before ordering to ensure proper fit.
Q: Is the GW 332 pre-assembled or does it require bearing installation?
A: The GW 332 comes with pre-installed bearings and is ready to mount directly onto your 0.75 inch axle. No bearing installation is required. Simply slide the wheel assembly onto the axle and secure with the appropriate cotter pin or axle nut according to your equipment specifications.
Q: What is the maximum load capacity of a pallet jack equipped with GW 332 wheels?
A: The GW 332 is rated for manual pallet jacks with up to 5500 lbs capacity. The virgin cast nylon and chrome steel bearings (SAE 52100) are engineered for this load range. Do not use on equipment rated above 5500 lbs without verifying structural compatibility with your manufacturer.
Q: How do I test if the GW 332 bearings are worn or failing?
A: Lift the pallet jack slightly and spin the wheel by hand. Listen for grinding or growling sounds and feel for rough spots during rotation. Excessive play when you push the wheel side-to-side indicates bearing wear. If noise persists after cleaning debris from the bearing area, the bearing must be replaced. A functioning bearing spins freely with minimal noise.
Q: What is the recommended replacement interval for the GW 332 in high-volume warehouse operations?
A: In continuous use environments, inspect the GW 332 every 3 months for bearing play, tread wear, and nylon core integrity. Plan replacement every 18-24 months depending on daily usage hours. High-intensity use with frequent direction changes may reduce lifespan to 12-18 months. Replace immediately if bearings develop noise or the wheel does not spin freely.
