Frequently Asked Questions
Q: Why would I choose GWK-4YX97-LW-N nylon wheels over the standard Ultra-Poly GWK-4YX97-LW?
A: Nylon wheels (GWK-4YX97-LW-N) are ideal for cold storage (freezer and cooler environments below 0 degrees Fahrenheit), wet areas, or rooms with high moisture. Nylon resists rust, corrosion, and brittleness in cold conditions. Ultra-Poly wheels become hard and crack in extreme cold. Choose nylon for food processing, frozen warehouses, or coastal/salt-air facilities.
Q: Are GWK-4YX97-LW-N wheels non-marking, and will they damage polished or waxed floors?
A: Solid nylon wheels are generally non-marking on standard warehouse floors. However, nylon can leave faint marks on high-gloss, freshly waxed, or polished display floors. For critical display areas, test in a concealed area first. Ultra-Poly (GWK-4YX97-LW) is safer for showroom use.
Q: What is the load rating for nylon wheels, and does cold storage affect performance?
A: Nylon wheels maintain their rated load capacity (up to 2000 pounds per wheel) even in freezing conditions. Unlike polyurethane, nylon does not become brittle or crack in cold. They perform consistently from -40 to +150 degrees Fahrenheit. Ensure axles and bearings are also cold-rated for below-zero use.
Q: Can I install GWK-4YX97-LW-N wheels on a Dayton 4YX98 jack, or only 4YX97?
A: Yes. The nylon load wheel kit GWK-4YX97-LW-N is compatible with both Dayton 4YX97 and 4YX98 models. The axle diameter, bearing size, and fastener specifications are identical. Always confirm the model number on your jack nameplate before installation.
Q: What is the typical lifespan of nylon wheels in cold storage, and when should I replace them?
A: Nylon wheels typically last 2 to 4 years in cold storage (used 10-20 hours per week). Replace them when you notice reduced rolling, flat spots, discoloration, cracks, or chunks missing. Nylon may discolor over time (yellowing or browning) but continues to function until structural damage occurs. Do not ignore cracks, as they can spread suddenly under load.
