Frequently Asked Questions
Q: Why choose GWK-PTH50-LW-SS over standard load wheel kits?
A: GWK-PTH50-LW-SS features stainless steel ball bearings instead of standard carbon steel bearings. Stainless steel eliminates rust and corrosion, making this kit ideal for food-service facilities, freezer environments, washdown areas, and any location with high moisture or chemical exposure. The stainless bearings are sealed and lubricated for life, reducing maintenance frequency. In wet environments, stainless bearings can provide 50 percent longer service life compared to standard steel. Choose GWK-PTH50-LW-SS if your pallet jack operates in corrosive conditions.
Q: What is the load capacity and wheel material of GWK-PTH50-LW-SS?
A: GWK-PTH50-LW-SS supports the full Crown PTH50 rated load capacity of 5000 lbs at a 24 inch load center. The kit contains two load wheel assemblies with ultra-polyurethane 70 Shore D wheels. The polyurethane provides excellent floor grip and rolling efficiency. Stainless steel ball bearings ensure corrosion resistance and smooth operation. The assembly includes all mounting hardware and is ready for direct installation without frame modification.
Q: Are there any published cross-reference part numbers for GWK-PTH50-LW-SS?
A: No cross-reference part numbers have been published for GWK-PTH50-LW-SS in available sources. This stainless steel variant is less common than the standard load wheel kit and does not have documented equivalents from competing manufacturers. If you need this specific kit, order directly by SKU from Crown distributors or authorized suppliers. Do not substitute the standard GWK-PTH50-LW if stainless bearings are required for your application, as standard bearings will not provide the corrosion resistance you need.
Q: How does GWK-PTH50-LW-SS installation differ from standard load wheel kits?
A: Installation is identical to standard load wheel kits. (1) Lower and unload the jack completely. (2) Remove cotter pins and axle nuts from existing wheels using a 9/16 inch wrench. (3) Slide old wheels off the axles. (4) Install new load wheel assemblies on the front axles, ensuring wheels are flush with the frame. (5) Reinstall axle nuts hand-tight, then back off one-quarter turn to allow free wheel rotation. (6) Secure with new cotter pins. The stainless bearings require no special installation procedure; they are sealed and ready to use immediately.
Q: What maintenance is required for stainless steel bearings in GWK-PTH50-LW-SS?
A: Stainless steel bearings are maintenance-free for the life of the wheel assembly. They are sealed and pre-lubricated at the factory. Do not attempt to clean, repack, or relubricate sealed bearings; this will damage the seals and allow contamination to enter. Inspect axle nuts and cotter pins quarterly to ensure they remain secure. In food-service or wet environments, wipe wheels clean weekly to prevent buildup of moisture or salt residue on the polyurethane surface. If a wheel develops noise or binding, the bearing seal has likely been compromised; replace the entire wheel assembly.
Q: What is the expected lifespan of GWK-PTH50-LW-SS in wet or food-service environments?
A: In controlled warehouse environments, GWK-PTH50-LW-SS wheels typically last 18 to 36 months. In wet, washdown, or food-service environments where standard steel bearings would rust within 6 to 12 months, stainless variants can extend service life to 24 to 48 months or longer. Actual lifespan depends on floor cleanliness, chemical exposure, and frequency of washdowns. Inspect wheels monthly for flat spots or polyurethane cracks. Stainless bearings will not rust, but the polyurethane wheel surface can still wear or degrade if exposed to strong caustic cleaners or oils; wipe wheels immediately after washdowns to prevent chemical absorption.
