    • Hole diameter (d): 80 mm
    • External Diameter (D): 140 mm
    • Width (B): 26mm
    • Sphere Diameter: 17,462 mm
    • Number of Spheres: 17
  • Load capacity:

    • Dynamic Radial Load (C): 85.2 kN
    • Static Radial Load (C0): 75 kN
    • Fatigue load limit (Pu): 3 kN
  • Limit Speed:

    • Grease lubrication: 9,500 rpm
    • Oil lubrication: 16,000 rpm
  • Weight: 1.46kg

  • Contact angle: 15°

  • Material of the Balls and Rings: High resistance chromed steel

  • Cage Material: Phenolic (reinforced resin)


Mechanical Characteristics:

  • Preload: Class B (light), which allows for greater axial and radial rigidity.
  • Precision tolerances: Class P4A (super precision) for high speed and precision applications.
  • Universal Configuration: The bearing can be mounted in different arrangements, such as back-to-back (<>), face-to-face (><), or tandem (>>), depending on the application.

Typical Applications:

  1. Machine tool spindles: Used in CNC machines and precision grinding machines to ensure accurate and stable performance at high speed.
  2. High-Speed ​​Machines: Ideal for drilling and milling machines, where high speeds are critical.
  3. Aerospace: Key component for actuators, gyroscopes and jet engines, where precision is vital.
  4. Medical Instrumentation: Useful in medical devices such as dental drills and high-speed imaging equipment.

Advantages of purchasing ready for delivery from stock:

  1. Immediacy of delivery: Guarantees immediate availability of the product, reducing downtime of machines and processes.
  2. Reduced cost: Buying in stock can offer economic advantages compared to a customized order, especially for large quantities.
  3. Quality control: SKF bearings are produced to high quality standards, ensuring reliable and consistent performance. Having products already available avoids production delays or non-compliance.

Description of the manufacturer (SKF):

SKF, founded in 1907, is a world leader in the production of bearings, sealing solutions and lubrication systems. Based in Sweden, the company stands out for the innovation and quality of its products. Their range of high precision bearings are used in numerous industrial and technological sectors, ensuring superior performance thanks to continuous research and development.


Related mathematical formulas:

  • Dynamic load capacity: The formula for determining the nominal bearing life (L10) is:

    L10=(CP)p×106L10 = \left(\frac{C}{P}\right)^p \times 10^6

    Where C is the dynamic load, P is the applied load, and p is an exponent based on the bearing type (for ball bearings, p = 3).

  • Limiting speed: Limiting speed is directly related to lubrication and heat dissipation. For high speeds, the use of lubricating oil is preferable.

These characteristics make the SKF 7216 CDGB/P4A bearing a component of excellence in the industrial and technical fields​
