10 Pack 6005 2RS Full Ceramic Si3N4 Bearings 25x47x12mm Sealed High Precision Ceramic Ball Bearings for Smooth Low Friction Performance and Long Life Durability
✔️ Pack of 10 sealed full ceramic bearings with Si3N4 races
These are sealed full ceramic ball bearings built with Si3N4 inner and outer races and a PTFE cage. They measure 25 mm ID, 47 mm OD, and 12 mm wide, and come in a 10-pack to simplify replacements on projects. Ideal for precision machinery, robotics, CNC, and environments where heat, moisture, or chemicals are a concern.
✅ Inner/outer races: Si3N4 ceramic for rigidity and wear resistance
✅ Balls: Si3N4 ceramic for high hardness and corrosion resistance
✅ Cage: PTFE for smooth operation at speed and low friction
✅ Sealing: 2RS design protects against dirt and moisture
✅ Pack size: 10 bearings for batch projects
💡 What is a sealed full ceramic bearing used for in precision machinery?
Handy choice for high-speed, harsh or moisture-prone environments where durability and friction control matter.
- low-friction performance for robotics and CNC applications - corrosion resistance in wet or chemical environments - long life under high-cycle, high-speed operation - compatibility with ceramic balls and PTFE cages in sealed designs
