JAPAN NSK 7012 High-Speed Angular Contact Ball Bearings for Machine Tools

Product Overview:

The JAPAN NSK 7012 Angular Contact Ball Bearings are specifically designed for high-speed machine tool applications, offering exceptional load capacity and reliability. With options for various contact angles, these bearings are optimized for handling heavy one-way axial loads, ensuring smooth and efficient operation in demanding mechanical environments.

Key Features:

• Contact Angle Options: Available in 15°, 30°, and 40° contact angles, denoted by C, A, and B. Special models also feature a 25° contact angle, marked as A5. The larger the contact angle, the greater the axial load capacity.
• High Load Bearing: Ideal for bearing substantial one-way axial loads, making them suitable for a wide range of industrial applications.
• Material Variants: Constructed from steel, brass, or engineering plastic, designed to accommodate various operational requirements. Can be produced through pressing or turning depending on the specific needs.
• Variety of Bearing Types: Includes single-row, matched, double-row, and four-point contact ball bearings to support various applications.

Applications:

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