Frequently Asked Questions
Q: What is the difference between the GW 9135-A1 and GW 9135-A-R?
A: The GW 9135-A1 has a 20mm bearing ID while the GW 9135-A-R has a 25mm bearing ID. They cannot be used interchangeably. The A1 is designed for smaller axle trucks, while the A-R is for larger diameter axles. Both have 3.25 inch diameter and 5 inch width, but the bearing size is the critical fitment dimension. Verify your truck axle diameter before selecting either model.
Q: What are the cross-references for GW 9135-A1?
A: The GW 9135-A1 is cross-referenced with GP 9135-A and GP9135-A (note the no-hyphen variant). OEM part number is shown as GW9135-A. When ordering replacement parts or checking inventory across suppliers, search for all these numbers as they represent the same wheel assembly. Some suppliers may list only one variant, so checking cross-references ensures you find compatible stock.
Q: Can I use the GW 9135-A1 on a Crown or Raymond lift truck?
A: The GW 9135-A1 is engineered for generic electric lift truck compatibility with 20mm axles. Crown, Raymond, HYG, and UniCarriers trucks may use different wheel assemblies. Check your truck manual or the existing wheel part number. Installing the wrong wheel size or bearing fit will cause axle misalignment and damage. Do not assume compatibility based on truck brand alone.
Q: How do I diagnose if my wheel bearing is failing on the GW 9135-A1?
A: Failing bearings produce distinct symptoms. Raise the truck so the wheel spins freely off the ground. Spin the wheel by hand. If it does not coast smoothly, produces grinding or squeaking noise, or slows down abruptly, the bearing is failing. Also listen for noise while the truck is running under load. If the wheel wobbles side to side when fully loaded, the bearing may have lost preload. Replace the entire assembly if any of these symptoms appear.
Q: What maintenance extends the life of the GW 9135-A1 wheel?
A: The GW 9135-A1 comes with sealed 2RS bearings (rubber seals both sides), which are low-maintenance. No greasing is required. Inspect monthly for visible damage, flat spots, or loss of tread texture. Clean wheels with a damp cloth to remove salt, debris, or chemicals that may degrade polyurethane. Do not store tires in direct sunlight or extreme heat. In harsh environments (salt, water, hot/cold cycling), expect 18-24 month lifespan instead of the typical 24-36 months.
Q: What is the weight and footprint of the GW 9135-A1 assembly?
A: The GW 9135-A1 has a 3.25 inch outer diameter and 5 inch width. The assembly (wheel plus bearing plus hub) typically weighs 2-3 lbs. These dimensions must fit within your truck fork or stanchion clearance. Measure the existing wheel location before installing to confirm there is adequate side-to-side clearance. If your truck has protective wheel guards, ensure the 3.25 inch diameter does not interfere with the guard geometry.
