High-Speed NSK Angular Contact Ball Bearings 7022 and 7024

High-Speed NSK Angular Contact Ball Bearings 7022 and 7024

NSK angular contact ball bearings 7022 and 7024 are designed for high-speed machine tool applications, providing superior performance and durability. With a range of contact angles and configurations, these bearings are engineered to handle significant axial and radial loads, making them suitable for various industrial machinery.

Features and Specifications:

• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and a special 25° (A5) version. The larger the contact angle, the higher the axial load-bearing capacity.
• Material and Construction: Constructed using high-quality steel balls with retainers made of steel, brass, or engineering plastic. Retainers are formed by pressing or turning, depending on the bearing type and operational conditions.
• Load Capacity: Primarily designed to support one-way axial loads. Bearings with a larger contact angle have a greater capacity for heavy load-bearing.
• Bearing Types: Designed in various configurations to suit multiple applications:
  • 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 enhanced performance
  • C9: Light preloaded, ideal for low torque requirements
  • PN7A: Standard precision (ISO4 class equivalent)
  • PN7B: Special controlled precision for inner and outer diameter variations (ISO4 grade, SU combination)

Applications:
