71914 CEGA/P4A Bearing Product Overview & Core Advantages
The 71914 CEGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Manufactured to P4A tolerance class, this bearing delivers superior running precision. Its 15° contact angle and extra light preload (Class A) make it ideally suited for high-speed operation, offering excellent performance under combined radial and axial loads. The open design, combined with a phenolic cage and factory lubrication, ensures optimal performance in high-precision spindles and other critical machinery.
71914 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71914 | Basic bearing designation indicating the size series and bore diameter (70 mm). |
| CE | Contact angle of 15°. |
| GA | Indicates a specific internal clearance and preload level (Extra light / Class A). |
| P4A | High precision tolerance class, superior to ABEC-7/ISO P4. |
71914 CEGA/P4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a phenolic resin cage, a 15° contact angle, and extra light preload enables a high limiting speed of 28,000 rpm, making it an excellent high-speed bearing.
- High Rigidity and Precision: Manufactured to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, this bearing provides stable and precise rotational performance, essential for applications requiring minimal runout.
- Superior Load Capacity: The angular contact design efficiently supports combined loads (simultaneous radial and axial loads). With a dynamic load rating of 4972 lbf and a static load rating of 3600 lbf, it offers reliable performance in demanding conditions.
- Universal Matching: Designed as a Universal Matchable (SU) bearing, it can be universally mounted in sets (typically 3 bearings) to achieve specific preload and stiffness characteristics without selective matching.
71914 CEGA/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally deployed in high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Spindles for PCB drilling and routing
- High-frequency Electric Motor Spindles
- Other high-speed precision machinery requiring high rigidity and accuracy
