6004 Roulement à billes entièrement en céramique Silicon Carbide 20mm Inner Diameter 42mm Outer Diameter 12mm Width Faible frottement pour les machines de précision et les applications industrielles. Résistance supérieure à l'usure, à la corrosion et aux hautes températures.

This 6004 full ceramic bearing uses silicon carbide SiC balls and PTFE cage, designed for high-speed, high-temperature, and corrosion-prone environments. It's commonly used in automation, packaging, and precision equipment where low friction and chemical resistance matter, and it serves as a high-performance alternative to traditional sealed ball bearings.

✅ 20 mm bore (ID)
✅ 42 mm outer diameter (OD)
✅ 12 mm width
✅ SiC ceramic balls with PTFE cage
✅ PTFE cage for smooth operation

💡 What is a handy use case for full ceramic bearings in demanding machinery?

These handy bearings excel in situations where dry operation, high speed, and chemical resistance are needed.

- High temperature tolerance for hot-running equipment

- Corrosion resistance in chemical processing environments

- Low maintenance in clean rooms or vacuum systems
