NSK Angular contact ball high speed machine tool bearings 7000

JAPAN NSK High-Speed Angular Contact Ball Bearings – 7000 Series

Product Overview:

The JAPAN NSK Angular Contact Ball Bearings 7000 Series are designed for high-speed machine tool applications, delivering excellent performance and precision. With various contact angles and construction materials, these bearings are suitable for handling heavy axial loads and ensuring smooth, reliable operation in different machinery.

Key Features:

• Versatile Contact Angles: Available in 15°, 30°, and 40° contact angles, indicated by letters C, A, and B. Special models also offer a 25° contact angle (designated as A5). The greater the contact angle, the higher the axial load capacity.
• Robust Load Bearing: Specifically designed to handle large one-way axial loads, making them ideal for various mechanical and industrial applications.
• Material Options: Made from steel, brass, or engineering plastic, providing flexibility depending on the application's needs. These materials can be pressed or turned into the required form for different use cases.
• Bearing Types: Includes single-row, matched, double-row, and four-point contact ball bearings to accommodate different requirements.

Applications:

Widely used in the mechanical industry, such as:

• Metallurgical machinery
• Mining machinery
• Paper-making machinery
• Textile machinery

Specifications:

• Brand: NSK 25TAC62BSBC10PN7A
  • 25: Inner diameter size in mm.
  • TAC: Thrust angular contact ball bearing, featuring a 60° contact angle.
  • 62: Outer diameter size in mm.
  • B: Internal construction style.

  • C10: Standard preloaded.
  • C9: Lightly preloaded with low torque.
  • PN7A: Standard precision (equivalent to ISO4 class).
  • PN7B: Special control precision (ISO4 grade, specific to SU combinations).

Bearing Combinations:

• Single (SU) and Double (DU) Columns: For free combinations.
• Back-to-Back (DB) and Face-to-Face (DF): For stability in applications.
• Three-Column (DBD, DFD, DTD) and Four-Column (DBB, DFF, DBT, DFT, DTT) Combinations: For enhanced load-bearing capabilities.

Advantages of Angular Contact Ball Bearings:

1. High Load Capacity: Designed to bear greater loads than deep groove ball bearings of the same dimensions.
2. Versatile Load Handling: Suitable for radial-axial combined loads or pure thrust loads.
3. High Speed and Low Friction: Optimized for smooth operation with a high limiting speed, ensuring low operating friction.
