High-Speed NSK Angular Contact Ball Bearings 7220 to 7224

NSK angular contact ball bearings 7220 to 7224 are designed for high-speed machine tool applications, providing exceptional precision, durability, and load-handling capacity. They are engineered to handle both axial and radial loads effectively, making them suitable for a variety of industrial machinery.

Features and Specifications:

  • Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5). Bearings with larger contact angles are designed to manage higher axial loads.
  • Material and Construction: Made from high-quality steel balls with retainers constructed of steel, brass, or engineering plastic. The retainers are formed through pressing or turning, depending on the bearing type and operational conditions.
  • Load Capacity: Primarily designed to handle significant one-way axial loads. Larger contact angles enhance the bearing's ability to support heavier loads.
  • Bearing Types: Available in various configurations to meet different application requirements:
    • Single Row Angular Contact Ball Bearing
    • Matched Angular Contact Ball Bearing
    • Double Row Angular Contact Ball Bearing
    • Four-Point Contact Ball Bearing
  • Combination Options:
    • DF: Face-to-face combination
    • DB: Back-to-back combination
    • DT: Tandem combination
    • SU: Single, free combination
    • DU: Dual column, free combination
    • 3-Column Combinations: DBD, DFD, DTD
    • 4-Column Combinations: DBB, DFF, DBT, DFT, DTT
  • Precision and Preload:
    • C10: Standard preloaded for improved performance
    • C9: Light preloaded, ideal for low torque applications
    • PN7A: Standard precision (equivalent to ISO4 class)
    • PN7B: Enhanced control precision for specific inner and outer diameter variations (ISO4 grade, SU combination)

Applications:

  • Mechanical Industries: Suitable for various industrial applications, including:
    • Metallurgical machinery
    • Mining equipment
    • Paper-making machinery
    • Textile machinery
  • Machine Tool Applications: Specifically designed to support ball screws in machine tools, ensuring high-speed operation and precision control.

Key Specifications:

  • Inner Diameter: Starting from 25 mm (0.98 inches)
  • Contact Angle: Available in options of 15°, 30°, 40°, and special 25° for flexible load-handling capabilities.
  • Thrust Angle: Provides optimal performance in applications requiring high thrust capacity with versatile combination options.
