Frequently Asked Questions
Q: What are the cross-reference part numbers for GW 684?
A: GW 684 is equivalent to GW 684-A, GP 684-A, and GP 684-A. All these part numbers refer to the same wheel assembly with identical specifications. When ordering replacement parts, use any of these interchangeable designations. Verify that the supplier confirms they are shipping the exact product regardless of which part number you reference.
Q: What are the exact dimensions and bearing specifications for GW 684?
A: GW 684 measures 8.000 inches outside diameter by 4.000 inches width (203.20 mm by 101.60 mm). The bearing ID is 30.000 mm, which corresponds to a 1.181 inch bore. This larger wheel size distributes load more effectively than smaller assemblies. Verify your truck axle diameter is exactly 30 mm before installation. Width accommodates standard electric pallet jack and lift truck platforms.
Q: Why would I choose GW 684 over a smaller wheel assembly?
A: The 8 inch diameter provides several advantages: larger contact patch for better traction and stability on uneven floors, reduced rolling resistance and energy consumption, improved thermal management during continuous operation, and extended tread life due to distributed wear across a larger surface area. This wheel is ideal for heavy-duty warehouse environments or trucks operating continuously with full loads. Smaller wheels wear faster under the same conditions.
Q: What does the 95A polyurethane tread rating mean for durability?
A: 95A Shore durometer polyurethane is a durable, medium-firm material that balances wear resistance with grip performance. This hardness is optimized for warehouse concrete floors and delivers approximately 24 to 36 months of service life under typical duty. The tread resists oil, grease, and common warehouse contaminants. Do not use this wheel on extremely rough surfaces or outdoor pavement; tread may chunk or delaminate prematurely.
Q: How do I diagnose and replace a failed GW 684 wheel?
A: Replace the wheel if you observe tread chunks missing, visible flat spots exceeding 0.25 inches, side-to-side wobble indicating bearing wear, or grinding noise during operation. To replace: lift the truck safely using a hydraulic jack, remove the axle fastener with an appropriate wrench, slide the old wheel off the axle, align the new wheel onto the axle bore, and torque the fastener according to manufacturer specifications. Rotate the wheel by hand to confirm smooth operation before lowering the truck.
Q: What is the maintenance interval for GW 684 wheels?
A: Inspect wheels every two weeks for tread condition and bearing noise. Verify axle fasteners are tight weekly; vibration from continuous operation can loosen hardware. Clean tread monthly with a damp cloth to prevent debris accumulation. Sealed bearings require no lubrication or repacking. When tread thickness reduces to 25 percent of original diameter or bearing noise increases, schedule replacement. Lifespan in continuous industrial duty is 24 to 36 months depending on load and floor conditions.
