Zealous Ceramic Bearings (Set, Built-In)

Zealous Ceramic Bearings — Product Description

Zealous Ceramic Bearings are a high-quality set of 8 bearings, designed for skateboards and longboards — especially for disciplines that rely on high speeds, low rolling resistance, and corrosion resistance (e.g., downhill, freeride, or high-speed cruising).

1. Product Type: Set of 8 precision bearings (built-in design with integrated spacers and speed rings).
2. Brand: Zealous.
3. Bearing Structure & Protective Elements:
4. Ceramic balls — lighter, stiffer, and corrosion-resistant.
5. Double-sided seals/shields (typically white seals on the ceramic variant) to keep out dirt and moisture.
6. Reinforced nylon cages/retainers for the balls.
7. Integrated spacers (.4045") and integrated speed rings (0.5 mm) — no additional small parts needed.
8. Technical Features:
9. Precision bore for 8 mm axles (standard skate/longboard).
10. Factory-lubricated with a nanoceramic or nano-enhanced special lubricating paste (Archoil / Nanoceramic type) that smooths out imperfections, hardens in the run-in area, and thus reduces friction.
11. Extremely low coefficient of friction (a very low value is stated in product specifications), reduces internal corrosion.
12. ABEC ratings vary by source; the bearings are designed for high-speed applications.
13. Application & Advantages:
14. Very fast right out of the box (short break-in period due to lightweight balls and low-viscosity factory lubrication).
15. Good corrosion resistance due to ceramic balls and special lubrication.
16. Practical built-in construction prevents loss of spacers/speed rings during maintenance changes.
17. Scope of Delivery: Set of 8 bearings (complete equipment: integrated spacers + speed rings, factory lubrication).
18. Care Instructions:
19. Regularly check for foreign objects; if necessary, clean carefully and re-lubricate with suitable bearing oil/grease (observe manufacturer's recommendations).
20. Ceramic bearings are sensitive to rough impacts — perform installation carefully.

This description summarizes the frequently stated product specifications and advantages of Zealous Ceramic Bearings and is intended for customers looking for a fast, durable set of bearings for skate and longboard use.
