NSK Angular contact ball high speed machine tool bearings 7000

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

Product Overview:

The JAPAN NSK Angular Contact Ball Bearings 7000 Series are designed for high-speed machine tools and industrial applications. Engineered with precision, these bearings are built to handle high axial loads in one direction, making them ideal for applications that require stability, durability, and smooth operation.

Key Features:

• Versatile Contact Angles: Available in contact angles of 15°, 30°, and 40°, designated by letters C, A, and B, respectively. Special brand production also offers a 25° contact angle, marked as A5.
• Load Capacity: Designed to bear heavy one-way axial loads. The greater the contact angle, the higher the load-bearing capacity, ensuring robust performance in demanding environments.
• Material Options: Constructed with steel, brass, or engineering plastic materials, suitable for a variety of uses. Bearings can be produced using pressing or turning, depending on application requirements.
• Variety of Bearing Types: Includes single-row angular contact ball bearings, matched angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings to suit different needs.

Application Areas:

• Widely used in the mechanical industry, including:
  • Metallurgical machinery
  • Mining machinery
  • Paper-making machinery
  • Textile machinery
