Design Features of CE7238SIPP Bearing

CE7238SIPP bearing is characterized by its use of silicon nitride (Si3N4) ceramic balls, combined with a single-row angular contact configuration. The single-row configuration is designed to support axial loads in one direction and radial loads, providing precise control and high-speed capabilities. CE7238SIPP bore dia is 190 mm. Its out dia is 340 mm. Its width is 55 mm. This bearing is designed for applications that require high-speed operation and precision.


What Benefits Can CE7238SIPP Bearing Provide?

  • High-Speed Performance: Ideal for high-speed applications due to silicon nitride's low density, reducing centrifugal forces.
  • Thermal Stability: Maintain consistent performance across a wide temperature range, ensuring reliability in varying operational conditions.
  • Wear and Corrosion Resistance: Exceptional resistance to wear and corrosion extends the bearing's lifespan and performance in harsh environments.
  • Electrical Insulation: The non-conductive nature of silicon nitride prevents electrical erosion, enhancing suitability in electrically sensitive applications.
  • Precision and Rigidity: The single-row design ensures precise control and high rigidity, crucial for applications requiring accurate motion control.


What Can CE7238SIPP Bearing Be Used for?

CE7238SIPP Bearing is well-suitable for applications such as:

  • High-Speed Machinery: Used in CNC machines, high-speed drills, and other machinery where rapid and precise motion is crucial.
  • Precision Instruments: Ideal for aerospace components and precision medical equipment due to their accuracy and reliability.
