NSK Angular Contact Ball Bearings 71908 to 71911 – High-Speed Machine Bearings

NSK Angular Contact Ball Bearings 71908 to 71911 – High-Speed Machine Bearings

The NSK Angular Contact Ball Bearings (71908 to 71911) are designed for high-speed and high-precision applications. Engineered to handle both radial and axial loads, these bearings are well-suited for machine tools, industrial machinery, metallurgic machinery, mining equipment, paper-making machinery, and textile machinery. With contact angles ranging from 15° to 60°, they offer excellent load-bearing capabilities, making them versatile for various mechanical applications.

Specifications:

• Bearing Types: Single Row, Matched, Double Row, Four-Point Contact
• Contact Angles: 15° (C), 30° (A), 40° (B), Special 25° (A5), and 60° (TAC)
• Material: Steel, Brass, or Engineering Plastic cages, depending on the application
• Load Capacity: High radial-axial combined load handling and pure thrust loads
• Combinations:
  • SU (Single)
  • DF (Face-to-Face)
  • DB (Back-to-Back)
  • DT (Tandem)
  • DBD, DFD, DTD (Three-Column Combination)
  • DBB, DFF, DBT, DFT, DTT (Four-Column Combination)
• Preload: Standard (C10) and Light Preload (C9) for low torque style
• Precision: Standard precision (PN7A, equivalent to ISO4 class), Special control precision (PN7B)

Product Features:
