Technical Specifications

Key Features & Benefits

• ABEC-9 High Precision: Exceptionally tight tolerances ensure minimal vibration and whisper-quiet, ultra-smooth rotation — perfect for high-speed cycling applications.
• Full ZrO2 Ceramic Construction: Both the rolling elements and raceways are crafted from premium zirconia ceramic — delivering superior wear resistance, long service life, and remarkable dimensional stability.
• Corrosion & Saltwater Resistant: Ceramic is naturally immune to rust and corrosion, making these bearings ideal for use in wet, humid, or saltwater fishing conditions.
• Grease-Free Self-Lubricating: Runs cleanly without grease, reducing maintenance requirements and keeping your drivetrain or reel spotlessly clean.
• Non-Magnetic & Electrically Insulating: The all-ceramic design provides excellent resistance to magnetic fields and electrical charge — a major advantage in specialized cycling and fishing environments.
• High-Temperature Tolerance: Performs reliably across a wide temperature range, making these bearings suitable for extreme working conditions.
• Lightweight: Ceramic is lighter than steel, contributing to overall weight reduction in performance cycling builds.

What Is a Full Ceramic Bearing?

Unlike standard steel or hybrid bearings, a full ceramic bearing features a ceramic outer ring, ceramic inner ring, and ceramic balls. Zirconia (ZrO2) ceramic is one of the toughest engineering ceramics available — combining hardness, chemical inertness, and self-lubricating properties. These qualities make full ceramic bearings the preferred choice in aviation, marine, automotive, chemical, and high-performance cycling sectors where steel simply cannot keep up.

Frequently Asked Questions

Q: What is the difference between the 15267 and 17287 ceramic bearing models?

A: The 15267 ceramic bearing measures 15mm bore × 26mm outer diameter × 7mm width, while the 17287 measures 17mm bore × 28mm outer diameter × 7mm width. Both feature the same ABEC-9 precision grade and full ZrO2 ceramic construction — the difference is purely dimensional to suit different bicycle or reel hub specifications.

Q: Are these ceramic bearings compatible with saltwater fishing reels?

A: Yes. Zirconia ceramic (ZrO2) is highly resistant to corrosion and does not react with saltwater or moisture. These bearings are an excellent upgrade for fishing reels used in marine or saltwater environments where steel bearings would quickly corrode.

Q: Do these bearings require any lubrication or maintenance?

A: These full ceramic bearings are designed for grease-free, free-running operation thanks to the inherently self-lubricating nature of ZrO2 ceramic. This significantly reduces maintenance compared to traditional steel bearings. Light ceramic-compatible oil can optionally be applied for specific high-load applications.

Q: What precision grade are these bearings and why does it matter?

A: These bearings are rated ABEC-9 — the highest standard precision grade for ball bearings. ABEC-9 bearings have extremely tight dimensional tolerances, resulting in less heat generation, less vibration, quieter operation, and greater efficiency at high rotational speeds compared to ABEC-3 or ABEC-5 rated bearings.
