6806-2RS Hybrid Ceramic Deep Groove Ball Bearings 30x42x7mm Si3N4 Silicon Nitride Balls Steel Rings Double Sealed Bearing for Motors, CNC Spindles (ABEC5)

Key Features

• Size 6806-2RS hybrid ceramic ball bearing (Inner Dia.=30mm, Outer Dia.=42mm, Thickness =7mm)
• Material The balls are made of silicon nitride (Si3N4) ceramic, which offers high hardness, high-temperature resistance, and corrosion resistance. The housing is made of bearing steel, providing excellent structural strength and durability
• High-Speed Capability Ceramic Si3N4 balls and bearing steel offer superior performance compared to traditional steel bearings, providing smoother rotation, reduced friction, and ceramic balls are insulated and anti-magnetic, suitable for electric field environments
• Double Sealed Sealed on both sides with rubber to protect against dust, dirt, and moisture, ensuring smooth operation and extending its lifespan
• ABEC5 Precision Bearing Lower manufacturing tolerances compared to lower-rated bearings, resulting in smoother rotation and less friction
