bearing designed for applications that require extremely high rotational speeds and a high degree of stiffness, such as machine tool spindles. The "BNR" designation indicates a specific series with an 18° contact angle, which is optimized for high-speed performance.

 

 

Key Features and Characteristics ⚙️

 

The BNR series is part of the ROBUST Series of bearings developed by manufacturers like NSK. They are engineered to overcome the challenges of high-speed rotation, which include heat generation, thermal deformation, and reduced service life.

 

  • Ultra High Speed: These bearings are specifically designed for high-speed operation, often capable of speeds that are 20% to 80% higher than conventional precision angular contact bearings.

  • Low Heat Generation: An optimized internal structure and advanced materials help to minimize friction and heat, which is crucial for maintaining the bearing's precision and longevity at high speeds.

  • High Rigidity: BNR bearings are often used in duplex (paired) or multi-bearing arrangements (e.g., back-to-back, face-to-face) to provide high rigidity and support for both radial and axial loads.

  • Material Variations: The bearings are available in different material configurations to suit various performance requirements.

    • S-type: Features steel balls and rings, offering a cost-effective option for high-speed applications.

    • H-type: Features ceramic balls (silicon nitride, Si3N4) and steel rings, which results in even lower heat generation and higher speeds.

    • X-type: Features ceramic balls and rings made from SHX steel, a specialized material with excellent seizure and wear resistance, allowing for even higher speeds and longer life.

       

  • Lubrication: The choice of lubrication is critical for these high-speed bearings. They can be used with grease lubrication at speeds where conventional bearings would need an oil-air system, and certain types (like the Spinshot™ XE) use a proprietary oil-air lubrication system to achieve speeds exceeding 2 million dmN.

  • Preload and Precision: BNR bearings come with a specified preload (e.g., extra light, light, medium) and high precision ratings (e.g., P3 or P4), which are essential for achieving the required running accuracy and rigidity in a spindle.

 

Applications 🛠️

The unique features of BNR series bearings make them ideal for applications that demand high-speed, high-precision, and reliable operation.

  • Machine Tool Spindles: This is the primary application for BNR series bearings. They are used in the main spindles of high-speed machining centers and grinding machines, where they enable faster cutting speeds and improved surface finish.

  • High-Speed Motors: The bearings are also used in high-speed electric motors and other rotary equipment where low vibration, low noise, and high speeds are required.

  • Other Industrial Machinery: Their ability to handle combined loads and operate at high speeds makes them suitable for various industrial applications, including certain types of pumps, compressors, and automation equipment.
