Frequently Asked Questions
Q: What is the bearing size on the GW 9135-A-R and is it interchangeable with the GW 9135-A1?
A: The GW 9135-A-R uses a 25mm (0.984 inch) bearing ID with a 6203-2RS precision ball bearing. The GW 9135-A1 uses a 20mm bearing ID. These are NOT interchangeable due to the different bore sizes. Using the wrong bearing will cause the wheel to bind or shift on the axle. Always verify your trucks axle diameter before ordering.
Q: Can I install the GW 9135-A-R wheel on a generic electric pallet jack?
A: The GW 9135-A-R is designed for electric lift trucks with a 25mm axle diameter. Generic pallet jacks typically use 20mm or 17mm axles. Installing this wheel on an incompatible axle will result in poor fit, wobbling, and potential wheel separation during operation. Measure your truck axle diameter before purchase.
Q: What does Shore 95A hardness mean and how does it affect performance?
A: Shore 95A is the polyurethane tread hardness rating. This moderate hardness provides good durability and load-bearing capability while maintaining reasonable grip on warehouse floors. Higher hardness (like 97A on the XL model) means greater wear resistance but slightly less grip. Lower hardness improves grip but wears faster. 95A is the standard for general-duty electric lift truck applications.
Q: How do I install the GW 9135-A-R wheel assembly?
A: Raise the truck using a hydraulic jack under the frame, never under the wheel. Remove the snap ring or cotter pin from the axle. Slide the wheel assembly off the axle. Clean the axle and inspect for burrs or damage. Slide the new wheel assembly onto the axle, ensuring the bearing seats fully. Reinstall the snap ring or cotter pin. Lower the truck and test roll. Do not apply full load until wheels have rotated freely for at least 30 seconds.
Q: What is the maximum load capacity and expected lifespan of the GW 9135-A-R?
A: The GW 9135-A-R is rated for the full load capacity of your electric lift truck (typically 2000-6000 lbs total). Lifespan depends on duty cycle and floor conditions. In typical warehouse use, expect 2-4 years before noticeable tread wear reduces grip and rolling efficiency. Inspect wheels every 6 months for cracks, flat spots, or wobbling. Replace immediately if the tread shows visible cracking or if the bearing no longer rotates freely.
Q: Is the GW 9135-A-R equivalent to the GW 9135-A?
A: The GW 9135-A-R and GW 9135-A are closely related but not identical. The -R suffix indicates a rebuilt or refurbished assembly, while GW 9135-A is the standard OEM part. Both use 25mm bearings and 95A hardness. Functionally they perform identically, but the -R may have a different warranty or cosmetic finish. Check with your supplier to confirm which is available for your application.
