Frequently Asked Questions
Q: What is the difference between GW L11 and GW L10 wheel assemblies?
A: Both GW L11 and GW L10 are 3 inch diameter, 3.75 inch width wheels with 6204RS bearings and identical load ratings. The main difference is the core material finish: GW L10 has a powder-coated steel core, while GW L11 has a plain steel core with no coating. GW L11 is used in environments where powdered coatings might interfere with mounting or where the application tolerates uncoated steel. Do not mix coated and uncoated wheels on the same jack; mounting interference can occur if dimensions are not identical.
Q: Is GW L11 suitable for outdoor or wet warehouse use?
A: GW L11 uncoated steel core is prone to surface rust in humid or wet environments. If the jack will operate outdoors or in a wet dock area, GW L10 with powder-coated steel is preferred. If only GW L11 is available, inspect the uncoated steel core monthly for rust development. Light surface rust does not affect function, but deep pitting or flaking can compromise the core structure. Apply a thin coat of light machine oil to the bare steel core to slow oxidation in high-moisture areas.
Q: How do I diagnose and replace a failed GW L11 wheel?
A: Symptoms of a failed GW L11 are squealing noise, rough or grinding sensation when spinning by hand, flat spots or chunks missing from the polyurethane tread, or slow descent speed. Lower the jack fully and lift the fork clear of the ground. Remove the cotter pin and axle nut. Slide the old GW L11 off the 16 mm axle. Clean the axle shaft with a wire brush to remove rust. Install the new GW L11 wheel, ensuring the steel core seats fully against the axle shoulder. Reinstall the washer, nut, and cotter pin. Verify smooth hand-spin rotation before lowering the jack back to the floor.
Q: What is the lifespan of a GW L11 wheel under typical warehouse conditions?
A: GW L11 wheels typically last 18 to 36 months in a medium-use warehouse moving 50 to 100 pallets per day. Heavy daily use with abrasive floors or rough handling reduces lifespan to 12 to 18 months. The non-coated steel core can develop surface rust over 1 to 2 years in standard humidity. Polyurethane Shore A 95 hardness tread gradually hardens and loses grip over time. Replace GW L11 wheels as soon as tread loss exceeds 20 percent or when the 6204RS bearing roughness develops; continuing operation on failed wheels can damage the axle and fork.
Q: Can I apply a protective coating to the GW L11 uncoated steel core?
A: Yes, but only light coatings that do not build up thickness. A thin coat of spray-on rust inhibitor or light machine oil applied annually helps protect the plain steel core from corrosion. Do not apply thick epoxy, paint, or enamel coatings; these can interfere with axle fit and cause binding. Allow any applied coating to dry completely before installing the wheel on the axle to avoid surface tackiness. Reapply protective coating after heavy rain or washdown operations. Light rust inhibitor is preferred over coatings because it remains thin and does not interfere with critical dimensions.
