NSK Angular contact ball high speed machine tool bearings 7200

JAPAN NSK 7200 High-Speed Angular Contact Ball Bearings for Machine Tools

Product Overview:

The JAPAN NSK 7200 Angular Contact Ball Bearings are engineered for high-speed applications in machine tools and various industrial machinery. These bearings handle substantial one-way axial loads efficiently and come in a variety of contact angles to suit different operational requirements. Made with precision and high-quality materials, they ensure reliable and consistent performance.

Key Features:

• Contact Angle Options: Available in 15°, 30°, and 40°, designated by the letters C, A, and B, respectively. Special versions with a 25° contact angle are marked as A5. A larger contact angle enhances the load-bearing capacity.
• Load Bearing: Designed to handle significant one-way axial loads. The greater the contact angle, the higher the load-carrying capacity.
• Material Construction: Manufactured using steel, brass, or engineering plastic. The production method, either pressing or turning, depends on the application requirements.
• Variety of Types: Available in single-row, matched, double-row, and four-point contact ball bearings, offering versatile solutions for various machinery.

Applications:

• Suitable for a range of industries, including:
  • Metallurgical machinery
  • Mining machinery
  • Paper-making machinery
  • Textile machinery
