Detailed Technical Data Sheet: SKF BA2-9178 Bearing

1. Product Description

The SKF BA2-9178 bearing is a high-precision angular contact ball bearing designed for excellent performance in industrial and high-speed applications. Also known by the acronyms 7213ACD/P4ADFB, B7213E.T.P4S.DFM and B7213-ET-P4S-DFM, it is designed to offer long life and low noise.

2. Construction and Materials

• Ball Material: High quality chrome steel, known for its hardness and wear resistance.
• Ring Material (Internal and External): Chrome steel or stainless steel, designed to ensure long life.
• Cage: Hard fiber cage (TB), which offers stable support and reduces friction.
• Lubrication: Standard lubrication to reduce friction and prevent premature wear.

3. Measurements and Technical Specifications

• Internal Diameter (d): 65 mm
• External Diameter (D): 120 mm
• Width (B): 46mm
• Weight: 2kg
• Contact Angle: 25 degrees
• Precision Tolerance: Class P4 (higher than P5), ensuring very tight tolerances and high precision.
• Bearing Type: Angular contact ball bearing, designed to support both radial and axial loads.
• Arrangement: X-arrangement, 2 (DF), indicating a pair of bearings mounted in an X configuration.

4. Mechanical Characteristics

• Radial Load Capacity: Adequate for applications with moderate radial loads.
• Axial Load Capacity: Suitable for axial loads in both directions thanks to the 25 degree contact angle.
• Tolerance and Precision: Class P4 for tight tolerances and high precision.
• Preload: GB - Medium preload, which helps maintain bearing rigidity and reduce axial play.

5. Mathematical Formulas for Characteristics

• Dynamic Load Capacity (C): The formula for calculating the nominal bearing life is:

  $$L$$

  Where:

  • L10L_{10} $L$ 10 ​=
  • CC $C$ = dynamic load capacity
  • FF $F$ = applied load
