Frequently Asked Questions
Q: What does nylon construction mean in GWK-CJ55N-CK wheels?
A: The wheel core is engineered nylon polymer bonded with polyurethane elastomer for the tread surface. Nylon cores are lighter than metal and more resistant to impact damage and corrosion. They maintain dimensional stability in extreme cold and wet environments better than traditional polyurethane-only wheels. Trade-off is slightly higher cost and lower maximum load rating compared to all-polyurethane designs.
Q: Is GWK-CJ55N-CK compatible with Clark CJ55 jacks or only CJ55N models?
A: GWK-CJ55N-CK fits both Clark CJ55 and CJ55N manual pallet jacks. The N designation in the SKU refers to nylon construction, not model restriction. However, verify wheel diameter and bore size match your jack documentation before installation. If your jack shows a different model number (such as CJ56 or CPI), do not force these wheels; order the correct kit.
Q: Why are nylon wheels quieter than steel wheels?
A: Nylon has inherent damping properties that absorb vibration and reduce noise transmission. When nylon wheels roll across concrete, the polyurethane tread surface compresses slightly and absorbs impact energy, preventing the loud clattering sound typical of steel wheels. This makes GWK-CJ55N-CK ideal for facilities with noise restrictions or where operator fatigue from noise is a concern.
Q: Can I use GWK-CJ55N-CK wheels in outdoor or wet environments?
A: Nylon cores perform well outdoors and in wet conditions, but polyurethane treads are not designed for extended water exposure. Use GWK-CJ55N-CK indoors, in cold storage, or in moist warehouses. For full-time outdoor use or high-pressure wash environments, do not use this kit. The nylon core will not rust, but water can degrade the polyurethane tread and bearing seals if the jack sits wet for extended periods.
Q: What maintenance does GWK-CJ55N-CK require?
A: Minimal maintenance. Wipe wheels clean of debris monthly. Check that wheels spin freely without resistance or noise. Nylon cores do not require lubrication. If a wheel begins to split or chunks separate from the polyurethane tread, replace that wheel immediately. Nylon wheels typically last 24 to 36 months with normal care, longer than polyurethane-only wheels, offsetting the higher initial cost.
