Product Description
This Complete Wheel Kit provides durable and high-performance wheels suitable for various pallet jacks, including Atlas and Zenith models. The kit features two Ultra-Poly Load Roller Assemblies (70D) and two Poly Steer Wheel Assemblies equipped with bearings, axles, and fasteners, ensuring easy operation and efficiency. Designed from ultra-polyurethane, these wheels resist damage from extreme temperatures and are non-marking, making them ideal for indoor use.
Compatibility: Fits pallet jacks made by Atlas, model Zenith 9. Alternate model: Zenith9. SKU: GWK-ATZ-CK

Frequently Asked Questions
Q: Is GWK-ATZ-CK compatible with both Atlas and Zenith Type 9 jacks, or just one brand?
A: Compatible with both. Atlas and Zenith Type 9 manual pallet jacks share the same frame geometry and wheel mount specification. The Zoro reference number G603968650 cross-references both brands. If your jack is labeled Zenith 9 or Atlas Type 9, this kit fits.
Q: What does GWK-ATZ-CK include and what does it not include?
A: Included: two Ultra-Poly 70D load roller assemblies (front wheels), two poly steer wheel assemblies (rear wheels), all bearings, axles, and fasteners. Not included: hardware for the jack frame itself, hydraulic seals, or steering linkage components. This is a wheel-only complete kit.
Q: Why is 70D Ultra-Poly better than standard polyurethane for Atlas Type 9 jacks?
A: 70D Ultra-Poly is harder and more durable than 92A standard polyurethane. It resists damage from temperature extremes and extends wheel life by 40-60% under typical warehouse conditions. Wheels remain non-marking, but roll smoother and quieter due to higher durometer. Drawback: slightly stiffer feel when pushing heavily loaded jacks on soft surfaces.
Q: How do I install GWK-ATZ-CK on a Zenith 9 jack that has worn wheels?
A: Steps: secure the jack horizontally on a bench or floor with outriggers locked. Remove fasteners from the first load wheel, slide out the old axle, and inspect the wheel mount for damage. Install the new 70D load roller assembly, ensuring the axle seats fully. Repeat for the second load wheel, then replace both steer wheels using identical steps. Verify all wheels rotate freely. Torque fasteners to 30 Nm.
Q: Are the steel axles and fasteners stainless or mild steel?
A: The kit uses mild steel axles and fasteners, not stainless. They are adequate for indoor warehouse use. If the jack operates in high-humidity or corrosive environments, inspect fasteners annually for rust. Apply a light coat of machine oil to axles after installation to prevent oxidation. Replace any corroded fasteners with grade 8 hardware.
Q: What is the expected lifespan of 70D wheels on an Atlas Type 9 under normal warehouse use?
A: Under 40-50 hour weekly warehouse use, 70D Ultra-Poly wheels last 2.5-3.5 years before wear requires replacement. Load wheels wear faster than steer wheels due to heavier stress. Inspect wheels quarterly for flat spots and cracks. Rotate wheels front-to-rear if wear is uneven. Store the jack indoors to minimize UV degradation.
