Product Description
This load wheel kit includes two Ultra-Poly 70D load wheel assemblies complete with bearings, axles, and fasteners. Made from high-quality materials, these wheels are designed to outperform standard 92A polyurethane wheels in durability and ease of movement, while being non-marking to protect floors. The kit is ideal for cold storage applications and environments prone to rust or corrosion, ensuring efficient operation in any industrial setting.
Compatibility: Fits pallet jacks made by Clark, model CJ55. SKU: GWK-CJ55-LW

Frequently Asked Questions
Q: What is the difference between GWK-CJ55-LW and GWK-CJ55-CK?
A: GWK-CJ55-LW contains only the two load wheel assemblies (front wheels). GWK-CJ55-CK is the complete kit with load wheels plus steer wheels (rear wheels). If you only have damage to the front load wheels and the rear steer wheels are still good, order the LW kit to save cost. If both front and rear are worn, order the CK kit.
Q: Are the sealed chrome steel bearings in GWK-CJ55-LW maintenance-free?
A: Yes. The sealed bearings do not require lubrication under normal use. Sealed design protects against dirt and moisture ingress. If a bearing shows play (side-to-side movement on the axle) after 2 to 3 years, replace the entire wheel assembly; individual bearing replacement is not practical. Do not attempt to open or re-grease sealed bearings.
Q: Is GWK-CJ55-LW non-marking and suitable for polished floors?
A: Yes. The Ultra-Poly 70D surface is non-marking and safe for display floors, showrooms, and polished concrete. It does not leave black tire residue. The wheels are also rated for cold storage environments down to minus 20 degrees Fahrenheit without becoming brittle. For extreme cold or specialty floor types, confirm the application with your supplier.
Q: Can I install the load wheels from GWK-CJ55-LW on the rear of my Clark CJ55?
A: No. Load wheels are sized and designed for front mounting (typically 3 inch by 3.75 inch with higher load rating). Steer wheels for the rear are a different size (typically 7 inch by 2 inch) with different hardness and bearing configuration. Installing load wheels in the rear will cause excessive noise, poor steering control, and premature wear. Always match wheel type to position.
Q: How long does GWK-CJ55-LW last under continuous daily use?
A: With normal warehouse use (8 to 10 hours daily on smooth floors), expect 18 to 24 months lifespan. In high-volume, high-density operations or rough concrete, lifespan may drop to 12 to 15 months. Cold storage environments do not significantly reduce lifespan. Inspect wheels every 6 months for flat spots and cracks. Replace before wheels fail completely to avoid jack malfunction.
