Frequently Asked Questions
Q: What is the bearing ID on the GW 9159-A and what are its cross-references?
A: The GW 9159-A has a 0.75 inch (19.05mm) bearing bore. Cross-reference part numbers include GW9159, GW 9159-A1, GW 9159-A2, GP 9159-A2, and GP9159-A2. The GW 9159-A is the base model with the smallest bore size. Verify your equipment bore specification before selecting which variant to order.
Q: What is the difference between GW 9159-A, GW 9159-A1, and GW 9159-A2?
A: All three are 4.000 inch diameter x 2.000 inch width assemblies in 95A polyurethane, but they differ in bearing ID. GW 9159-A has 0.75 inch (19.05mm) bore, GW 9159-A1 has 25mm bore, and GW 9159-A2 has 20mm bore. Match the bearing ID to your equipment axle diameter. Do not force-fit an incorrect bore size.
Q: Is the GW 9159-A a complete wheel assembly or does it need installation?
A: The GW 9159-A is a pre-assembled wheel with integrated bearings. It is ready to mount directly onto your equipment axle. No bearing installation is required. Slide it onto the axle and secure with the retaining fastener. Verify smooth rotation before placing the equipment in service.
Q: Can I interchange the GW 9159-A with other Durarun wheel assemblies?
A: No. The GW 9159-A series wheels are specific to axle bore diameters. Using the wrong bore size will result in loose fitment, wheel wobble, and premature bearing failure. Always verify the axle diameter specification from your equipment documentation before purchasing a replacement wheel assembly.
Q: What maintenance steps should I follow for the GW 9159-A?
A: Rotate the wheel by hand monthly to check for smooth operation and noise. If you hear grinding or feel resistance, the bearing may be damaged and the assembly should be replaced. Do not attempt to repack or repair bearings in molded assemblies. Inspect the polyurethane tread for uneven wear patterns indicating misalignment.
