Frequently Asked Questions
Q: What are the specifications and intended use of the GW 132 wheel assembly?
A: The GW 132 is a 3.000 inch diameter x 3.700 inch width poly load wheel assembly with a 0.75 inch (19.05mm) bearing ID. The wider 3.700 inch width distributes load across a broader contact surface, making it ideal for heavy-duty manual pallet jacks that operate on hard surfaces. The polyurethane tread is floor-safe and provides high load capacity with minimal noise.
Q: How do I verify the GW 132 fits my pallet jack?
A: Measure your current wheel diameter (must be 3.000 inch) and width (must be 3.700 inch). Check the axle bore diameter, which must be 0.75 inch or 19.05mm ID. If your jack currently has wheels with a 20mm ID bearing, the GW 132 will not fit due to bearing incompatibility. Mixing different bearing ID sizes on the same jack is not recommended. Verify the axle shaft diameter matches the bearing inner bore before ordering.
Q: Is the GW 132 compatible with the GW 133 or other wheel models on the same jack?
A: No. Do not mix wheel models with different bearing ID sizes on a single jack. The GW 132 has a 0.75 inch ID, while models like GW 131, GW 134, and GW 135 use 20mm ID bearings. Mixing will cause improper fit, binding, and uneven load distribution. All four wheels on a jack must be identical specification and the same model.
Q: What is the installation procedure for the GW 132?
A: Lower the jack fully to a stable position. Remove the cotter pin and axle fastener from one wheel assembly. Slide the old wheel off the axle shaft. Align the GW 132 bearing bore with the axle shaft and slide the wheel on smoothly. Insert and secure the axle bolt with the cotter pin. Repeat for remaining wheels. Test each wheel for smooth rotation and verify no binding. Install all four wheels before resuming normal jack operation.
Q: What is the load rating and expected lifespan of the GW 132?
A: The GW 132 polyurethane tread is rated for manual pallet jacks with typical capacities up to 5000 lbs. The sealed ball bearings reduce friction and extend service life to 3-6 years with normal use. Lifespan depends on floor conditions, load consistency, and maintenance. Wheels used primarily indoors on smooth concrete last longer than wheels used on outdoor or uneven surfaces. Replace when tread depth becomes uneven, cracking appears, or bearing rotation becomes stiff.
Q: How should I maintain the GW 132 wheel assembly?
A: Inspect wheels every 2-3 weeks for foreign objects, cracks, or flat spots. Clean the polyurethane tread with a damp cloth to remove dust and contaminants that reduce grip. The sealed bearings do not require lubrication. If wheels begin to squeak or resistance increases, bearings may be failing and should be inspected or replaced. Avoid prolonged exposure to oil, grease, or harsh chemicals, which can degrade polyurethane. Operate within the jack capacity rating to prevent premature wear.
