Frequently Asked Questions
Q: What bearing size does the GW 9159-A1 have and what equipment does it fit?
A: The GW 9159-A1 has a 25mm bearing bore (0.984 inch ID). This wheel assembly is designed for equipment with 25mm axles. It is a 4.000 inch diameter x 2.000 inch width assembly in 95A polyurethane. Confirm your equipment axle specification matches 25mm before ordering.
Q: How does the GW 9159-A1 compare to the GW 9159 wheel only?
A: The GW 9159-A1 is a complete assembly with pre-installed bearings ready for immediate mounting. The GW 9159 is a wheel only that requires separate bearing installation. The GW 9159-A1 is the better choice if you need a drop-in replacement that requires no assembly work.
Q: What installation steps are required for the GW 9159-A1?
A: Slide the GW 9159-A1 wheel assembly onto the 25mm diameter axle. Push firmly until seated. Secure with the axle retainer nut or clip according to your equipment design. Spin the wheel by hand to verify smooth rotation. Do not over-tighten the retainer as this can bind the bearing.
Q: Can I use the GW 9159-A1 on equipment with a different bore size?
A: No. The 25mm bore is not interchangeable with 0.75 inch or 20mm bore equipment. Forcing the wheel onto an incorrect axle size will damage the bearing and wheel assembly, resulting in failure and equipment downtime. Always measure or verify your equipment axle diameter before purchasing.
Q: How long should the GW 9159-A1 last in continuous operation?
A: Under normal operating conditions with proper maintenance, the GW 9159-A1 bearing assembly typically lasts 2-3 years depending on load intensity and surface conditions. Inspect the wheel tread every 6 months. Replace the assembly if polyurethane wear exceeds 30 percent or if bearing rotation becomes rough or noisy.
