Frequently Asked Questions
Q: What is the wheel diameter and width of the GW 9166?
A: The GW 9166 measures 3.500 inches in diameter by 2.000 inches in width (3.5 x 2 wheel, or 88.90mm x 50.80mm in metric). These dimensions apply to the outer wheel profile. The bearing bore ID is 20.000mm (0.787 inch).
Q: Is the GW 9166 the same as GW 9166-A or GW9166?
A: GW 9166, GW 9166-A, and GW9166 are cross-reference part numbers for the same 95A poly caster wheel. All three SKUs refer to the identical 3.5 x 2 wheel with cast iron core and machined finish. Verify your original part number on the equipment to confirm which reference applies to your truck.
Q: What does 95A durometer mean for the GW 9166?
A: 95A refers to Shore A hardness, which measures polyurethane tread stiffness. A 95A wheel is hard and long-wearing, ideal for industrial electric lift trucks. It resists cutting and gouging better than softer wheels but provides less shock absorption. It is suitable for smooth warehouse floors and light-to-medium load handling.
Q: What is the GW 9166 core material, and can I replace just the tread?
A: The core is cast iron with a machined finish. The 95A polyurethane is bonded to this core as a permanent assembly. You cannot replace the tread alone; the entire wheel assembly must be replaced when the tread is worn or damaged. Attempting to re-tread or repair the wheel is not recommended.
Q: Does the GW 9166 require press-fit installation?
A: The GW 9166 features a press-fit mounting interface. You will need a bearing press or hydraulic arbor press to install bearings onto the 20mm bore shaft. If bearings are not pre-installed on your assembly, do not attempt to hammer the bearing on; use proper pressing equipment to avoid bearing damage.
Q: What is the maximum load capacity of the GW 9166?
A: The GW 9166 is rated for electric lift truck and pallet jack applications with standard load ratings between 2,000 and 5,000 lbs per wheel, depending on the truck design and number of wheels in use. Always consult your equipment manual for exact load limits. Overloading will cause accelerated wear and bearing failure.
