Frequently Asked Questions
Q: Is this kit only for electric pallet jacks, and will it work on manual RPX models?
A: GWK-RPX60B-LW is engineered specifically for Barrett RPX60B electric pallet jacks. Do not install on manual RPX or other electric models. The wheel configuration, axle dimensions, and fastener specs are calibrated for the RPX60B frame geometry. Using an incorrect kit creates misalignment and premature bearing failure.
Q: What is the Durarun brand, and is it equivalent to other polyurethane wheel suppliers?
A: Durarun is a proprietary polyurethane formulation designed for heavy-duty electric pallet jack applications. At 95A Shore durometer, Durarun offers optimized load distribution and wear resistance compared to generic polyurethane. Using Durarun wheels maintains OEM performance and warranty compliance. Do not substitute with aftermarket or equivalent brands, as tread compound affects the electrical grounding properties of the jack.
Q: What does hardened steel axle with Rockwell C45 minimum hardness mean?
A: Rockwell C45 specifies the hardness and material quality of the axle shaft. This hardness prevents axle bending or deformation under the combined weight of an electric jack (which is heavier than manual models) and full loads up to 6000 lbs. Softer axles can bend, causing wheels to bind or lock. Always use OEM-specified hardened steel axles.
Q: What is the difference between the bearing in this kit and standard sealed bearings?
A: GWK-RPX60B-LW uses chrome alloy steel precision-ground bearing races with polyamide cages. This configuration handles higher speeds and continuous duty cycles typical of powered equipment. Chrome alloy reduces friction and heat generation compared to standard ball bearings. The polyamide cage (instead of steel) reduces weight and improves high-speed performance.
Q: What is standard duty cycle, and does this kit support higher usage rates?
A: Standard duty cycle means 4 to 6 hours of daily usage. This kit is engineered for continuous material handling operations at that level. If your facility runs 24 hour or multi-shift operations, verify expected runtime with your parts supplier. Heavy use beyond design parameters can accelerate wheel wear and bearing fatigue.
Q: What maintenance is required after installation?
A: After installation, verify all fasteners are torqued to specification (consult Barrett RPX60B manual) and that wheels rotate without noise or binding. Perform weekly visual inspections for debris wrapped around axles or bearing contamination. Do not wash or submerge the jack, as water can penetrate sealed bearings. Wipe wheels with a dry cloth to remove dust and debris.
