71914 CB/HCP4ADGA Bearing Product Overview & Core Advantages
The 71914 CB/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable bearing features a 15° contact angle and is supplied in a pre-loaded, duplex set (SU arrangement), enabling it to handle combined radial and axial loads simultaneously. Manufactured to P4A tolerance class, it offers superior running accuracy and rotational stability. The use of ceramic balls and a phenolic cage contributes to its high-speed capability, low friction, and extended service life, making it ideal for high-reliability, high-rigidity applications.
71914 CB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CB | Specific internal design and clearance for universal matching. |
| HC | Hybrid Ceramic: Signifies the use of ceramic balls, which reduce weight and friction, enabling higher speeds and longer life. |
| P4A | High Precision Tolerance Class: Exceeds ABEC 7/ISO P4 standards, ensuring extremely tight dimensional and running accuracy. |
| DGA | Universal Matchable (SU): Indicates the bearing is ground for universal duplex mounting (Face-to-Face or Back-to-Back) to accommodate various load conditions. |
71914 CB/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The duplex set configuration and angular contact design provide high system rigidity, enabling the bearing to support significant combined loads (radial and axial).
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage minimizes centrifugal forces and ensures stable operation at the high limiting speed of 31,000 rpm.
- Exceptional Precision: Manufactured to P4A tolerance class with a 15° contact angle, this bearing guarantees minimal runout and vibration, which is critical for precision machinery.
- Optimized for Matched Sets: The universal matchable (SU) design allows for simplified mounting in pre-loaded pairs, providing flexibility in application design and enhancing overall system performance.
