Design Features of CEZR 627 Bearing

CEZR 627 Bearing is a ball bearing that utilizes balls made from zirconia (zirconium dioxide - ZrO₂) ceramic as the rolling element. CEZR 627 bore dia is 7 mm. Its out dia is 22 mm. CEZR 627 width is 7 mm. Its ability to operate under high-speed conditions, coupled with its resistance to various challenging environments, makes it the go-to choice for professionals seeking both durability and precision. This bearing stands outs as a quintessential blend of precision engineering and material science. 

 

What Benefits Can CEZR 627 Bearing Provide?

  • Low Friction: It inherently has a lower coefficient of friction compared to traditional steel ball bearings.
  • Wear Resistance: Zirconia's hardness gives this bearing superior wear resistance, prolonging its service life.
  • Non-Conductive: CEZR 627 bearing is electrically non-conductive, making it suitable for applications where electrical insulation is crucial.
  • Thermal Stability: Zirconia ceramic retains its properties over a wide range of temperatures and showcases excellent thermal stability.
  • Corrosion Resistance: The ceramic material is resistant to various corrosive agents, making this bearing ideal for hostile environments.

 

What Can CEZR 627 Bearing Be Used for?

CEZR 627 Bearing excels in unique applications due to its specific properties:

  • High-Temperature Environments: such as furnace conveyor systems or aerospace applications.
  • Corrosive Settings: such as equipment in chemical processing plants or marine applications.
  • Electrical Insulation: such as Electric motors or generators.
  • Cleanroom Operations: such as Semiconductor manufacturing or pharmaceutical production units.
  • High-Speed Tools and Devices: such as dental drills or precision spindles operating at elevated RPMs.
