Design Features of CESI MR128 2RS Bearing

CESI MR128 2RS Bearing is a precision bearing designed with balls made from silicon nitride (Si3N4), a type of advanced ceramic material. CESI MR128 2RS bore dia is 8 mm. Its out dia is 12 mm. CESI MR128 2RS width is 3.5 mm. This bearing offers superior performance in terms of resistance to heat, corrosion, and wear, making it ideal for specific applications where these properties are crucial.

 

What Benefits Can CESI MR128 2RS Bearing Provide?

  • High-Temperature Resistance: Silicon nitride's ability to withstand extreme temperatures ensures this bearing maintain its performance even in heat-intensive applications.
  • Corrosion and Chemical Resistance: CESI MR128 2RS Bearing remains durable in environments exposed to corrosive chemicals.
  • Low Friction: Reduced friction attributes to minimal wear, less heat generation, and an extended operational lifespan of the bearing.
  • Non-Magnetic: Being ceramic, silicon nitride is inherently non-magnetic, making CESI MR128 2RS Bearing ideal for applications where magnetic interference is a concern.
  • Electrical Insulation: Silicon nitride is non-conductive, making it ideal for applications requiring electrical insulation.

 

What Can CESI MR128 2RS Bearing Be Used for?
