Bulk 15-Pack Zirconia Ceramic Bearing 6808-2RS 40x52x7
✔️ 40mm ID, 52mm OD, 7mm width; full ceramic ZrO2 bearing

These full ceramic bearings use Zirconia (ZrO2) races and PTFE cages, delivering superior wear resistance and low friction for precision machinery. They’re common in high-speed spindles, medical devices, and clean-room automation where metal bearings can fail or contaminate surfaces.

✅ Inner diameter: 40 mm
✅ Outer diameter: 52 mm
✅ Width: 7 mm
✅ Race material: Zirconia (ZrO2); Cage: PTFE
✅ Seals: 2RS (dual rubber seals)
✅ Pack size: 15 bearings

💡 What is a full ceramic ball bearing used for and why zirconia?

Handy in tough environments where metal bearings wear out or contaminate surfaces.

- High hardness and lightweight for precise motion
- Excellent corrosion resistance in damp or chemical environments
- Low friction and long service life in high-speed or clean-room setups
