Frequently Asked Questions
Q: What trucks is the GW 9166-A caster compatible with?
A: The GW 9166-A is designed for electric lift trucks and pallet jacks that require a 3.5 x 2 caster wheel with a 20mm bearing bore. It is interchangeable with GP 9166-A and GP9166-A. Always verify your truck model and current wheel dimensions before ordering to ensure fitment.
Q: What is the tread hardness and core material of the GW 9166-A?
A: The GW 9166-A has a tread hardness of 95 Shore A polyurethane bonded over a high-impact polymer core. This combination provides excellent wear resistance and durability on indoor warehouse and manufacturing floors. The molded polyurethane construction creates a monolithic wheel assembly.
Q: Does the GW 9166-A have a specific hub length, and why does it matter?
A: The GW 9166-A has a 47mm hub length that provides stability and support. Hub length affects how the wheel sits on the axle and how loads are distributed. A 47mm hub length prevents excessive side play and lateral wobble during turning. Do not substitute wheels with different hub lengths, as this will cause binding or excessive play.
Q: Is the GW 9166-A a non-marking wheel?
A: The specifications indicate this is a standard poly wheel assembly. Poly wheels are generally considered low-marking or non-marking under normal conditions. However, under heavy loads or hard braking, some black residue may deposit on light-colored floors. Test the wheel on your specific floor type if non-marking performance is critical.
Q: Can I use the GW 9166-A as a replacement for a worn-out GP 9166-A?
A: Yes. The GW 9166-A is equivalent to GP 9166-A and GP9166-A and can be used as a direct replacement. Both have the same 3.5 x 2 dimensions, 20mm bearing bore, and 95 Shore A tread hardness. You can swap one for the other without modification to your truck or axle assembly.
Q: How should I maintain the GW 9166-A to extend its lifespan?
A: Inspect the wheel weekly for damage, flat spots, or cracks. Keep the truck at the recommended load capacity and avoid sudden accelerations or hard stops. Lubricate bearings per your truck manufacturers schedule. Clean the floor of debris that could cause accelerated tread wear. Under normal warehouse use, the wheel should last 12-18 months before replacement is needed.
