One piece full ceramic zirconia bearing with double sided seal from the 6800 series. The 6801 variant is sized 12x21x5 mm and is supplied as a single piece. This bearing combines the advantages of ceramic construction with robust sealing for demanding environments. Key benefits hardness and wear resistance: zirconia ceramic provides durability and low wear in demanding applications. Low friction and smooth operation: ceramic bearings deliver reduced torque and quieter performance, especially at speeds. corrosion and chemical resistance: inert ceramic material stands up to moisture, chemicals, and cleaning agents. Non magnetic and non conductive: ideal for environments where magnetic interference or electrical concerns matter. Double sided seals: seals on both sides help retain lubricant and protect against contaminants, enhancing life span and reliability. Key attributes Material: full ceramic zirconia (ZrO2) bearing Seal: double sided seal for enhanced containment and protection Size variant: 6801 with dimensions 12 x 21 x 5 mm (inner diameter x outer diameter x width) Series compatibility: part of the 6800 family of bearings One piece per : ships as a single bearing Functional highlights Precision performance in tight tolerance assemblies Consistent operation under load and speed Suitable for applications requiring clean, stable, and longlasting bearings Applications and use cases speed automation and robotics: smooth rotation with reduced wear in joints and actuators Precision machinery and CNC components: reliable support for shafts in demanding operating conditions Medical and clean environments: non metallic, inert bearing suitable for sensitive equipment and clean rooms How this bearing helps you Extends service life in challenging environments due to ceramic durability and double seal protection Improves reliability in speed or precisiondriven equipment by reducing friction and maintaining stable operation Provides a non magnetic, chemically resistant option for specialized machinery and devices Note on sizing and compatibility The included size specification corresponds to the 6801 12x21x5 mm variant. Bearings in the 6800 series share the same family design, making this model a representative option for compatible assemblies requiring a full ceramic zirconia bearing with double sided sealing.
