Design Features of CESI R3A Bearing

CESI R3A Bearing is a precision bearing designed with balls made from silicon nitride (Si3N4), a type of advanced ceramic material. CESI R3A bore dia is 0.1875". Its out dia is 0.625". CESI R3A width is 0.196". 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 R3A 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 R3A 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 R3A 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 R3A Bearing Be Used for?

CESI R3A Bearing excels in unique applications due to its specific properties:

  • Precision Machine Tools: Especially in high-speed spindle applications where precision and reduced friction are paramount.
  • Electric Motors: Used in settings where high efficiency and performance are required. The non-conductive nature ensures minimal electrical interference.
  • Aerospace Equipment: For instruments and systems sensitive to weight and where resistance to extreme conditions is essential, like satellite gyroscopes and guidance systems.
  • Medical Devices: In high-performance equipment like MRI machines, surgical instruments, and dental drills, where precision, hygiene, and reduced noise are crucial.
  • High-Performance Vehicles: In race cars or motorcycles, for wheel and engine bearings, to handle high speeds with reduced heat production.
