6803 Full Ceramic Bearing 17x26x5mm

6803 Full Ceramic Ball Bearing
✔️ 17x26x5mm - ZrO₂ Ceramic with PTFE Cage

The 6803 full ceramic bearing is designed for extreme conditions where metal bearings fall short. Built entirely from Zirconia (ZrO₂) with a PTFE cage, it’s lightweight, corrosion-resistant, non-magnetic, and capable of handling high temperatures, ideal for cleanrooms, chemical environments, or high-speed applications.

✅ Full ceramic design: Zirconia (ZrO₂) inner & outer rings
✅ Balls: Zirconia ceramic for smooth, long-lasting rotation
✅ Cage: PTFE (Polytetrafluoroethylene) for low friction
✅ Dimensions: 17mm ID x 26mm OD x 5mm Width
✅ Max temperature: 356°F (180°C)
✅ Quantity: 1 bearing

☑️ Equivalent to: 61803

💡 Why use full ceramic bearings in advanced machinery?
Full ceramic bearings are perfect for specialized, high-demand conditions.

• Resist corrosion, moisture, and most chemicals

• Non-conductive and non-magnetic

• Perform well under thermal stress and at high RPMs

• Ideal for cleanrooms, medical, or semiconductor applications

If you’re dealing with harsh environments or high-performance builds, this 6803 ceramic bearing is your low-friction solution. Add one to your project and run smoother under pressure.
