Frequently Asked Questions
Q: What are the key features and specifications of the GW 135 wheel assembly?
A: The GW 135 is a 3.000 inch diameter x 3.750 inch width poly load wheel assembly featuring a steel core hub with polyurethane tread, sealed ball bearings, and a 20mm bearing ID. The 3.750 inch width is the widest in its class, providing excellent load distribution and stability. Sealed bearings ensure smooth, quiet operation with minimal maintenance. The polyurethane tread is floor-safe and delivers reliable performance for manual pallet jacks across various applications.
Q: How do I verify the GW 135 is compatible with my pallet jack?
A: Inspect your current wheels and measure three specifications: diameter (must be 3.000 inch), width (must be 3.750 inch), and bearing bore ID (must be 20mm). The wider 3.750 inch width is not interchangeable with narrower models like the GW 132 (3.700 inch) or GW 134 (3.500 inch). Verify your jack axle width accommodates the 3.750 inch wheel before installation. If your jack currently uses 0.75 inch ID bearings, the GW 135 will not fit.
Q: Does the GW 135 provide quieter operation compared to other wheel models?
A: Yes. The GW 135 sealed ball bearings and polyurethane tread reduce friction and vibration, resulting in quieter operation than steel wheels or unsealed bearing assemblies. The wider 3.750 inch contact surface also distributes load more evenly, reducing noise from uneven wear patterns. This makes the GW 135 an excellent choice for environments where noise control is important, such as warehouses with strict noise limitations or facilities operating during night shifts.
Q: What is the correct installation procedure for the GW 135 wheel?
A: Lower the jack fully and position on a level, stable surface. Remove the cotter pin and axle bolt from the wheel location. Slide the old wheel off the axle shaft completely. Position the GW 135 with the 20mm bearing bore aligned with the axle shaft. Slide the wheel onto the axle, ensuring the bearing bore seats fully against any shoulder or stop. Insert the axle bolt and cotter pin, securing tightly but avoiding over-tightening. Spin the wheel by hand to confirm free rotation before placing the jack under load.
Q: What is the load capacity and expected service life of the GW 135?
A: The GW 135 is rated for manual pallet jacks with capacities up to 5000 lbs total, with approximately 1250 lbs per wheel. Sealed bearings and polyurethane tread durability extend service life to 4-7 years under normal operating conditions. The wider wheel distributes loads more evenly, potentially extending lifespan compared to narrower assemblies. Actual lifespan depends on floor conditions, load consistency, and maintenance. Replace wheels showing tread separation, cracks, flat spots, or bearing resistance.
Q: What maintenance requirements does the GW 135 have?
A: Inspect wheels every two weeks for debris, damage, or uneven wear patterns. Clean the polyurethane tread with a damp cloth monthly to remove dust and contaminants. The sealed bearings require no greasing and should never be opened or tampered with. Check axle fasteners and cotter pins monthly to ensure they remain secure. If wheels develop squeaking, resistance, or visible bearing damage, replace the wheel assembly. Store jacks in cool, dry locations when not in use. Do not expose wheels to extreme heat, cold, or harsh chemicals for extended periods.
