71914 CDGC/P4A Bearing Product Overview & Core Advantages
The 71914 CDGC/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle is optimized to support significant combined loads, effectively handling both radial and unidirectional axial forces. The phenolic cage and universal matching (SU) designation make it ideal for high-speed spindle arrangements and other demanding precision machinery.
71914 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71914 | Basic bearing series and size designation (70mm bore, 100mm OD). |
| C | 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| DG | Universal Matchable (Universal Matchable (SU)). Bearings are manufactured to universal matching standards and can be paired in any combination. |
| C | Moderate preload (Class C), providing increased rigidity for precision applications. |
| P4A | High-Precision Tolerance Class, offering extremely tight dimensional and running accuracy tolerances. |
71914 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a Moderate (C) preload ensures high system rigidity, minimizing deflection under load for superior machining or positioning accuracy. Manufactured to P4A tolerance class, it guarantees exceptional running precision.
- Superior Load Capacity: The 15° contact angle enables the bearing to support substantial combined radial and axial loads simultaneously, making it versatile for complex loading conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at high rotational speeds up to 24,000 rpm. The open design facilitates efficient lubrication management.
- Universal Matching Capability: Designated as Universal Matchable (SU), these bearings can be universally paired in sets (typically 2 or more) to create a pre-loaded, rigid system without selective matching, simplifying inventory and assembly.
71914 CDGC/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables: CNC indexing and positioning systems.
- High-Frequency Motors and Spindles: Where high rotational speed and accuracy are critical.
- Medical and Dental Equipment: High-speed handpieces and scanners.
- Aerospace Actuation Systems: Precision gearboxes and control surface actuators.
