S71914 CD/P4A Bearing Product Overview & Core Advantages
The S71914 CD/P4A is a high-precision angular contact ball bearing designed for demanding applications. Engineered to a P4 (ABEC-7) tolerance class, it delivers exceptional running accuracy and rotational stability. Its key advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and thrust loads in one direction—making it an ideal choice for high-speed spindles and precision machinery where high rigidity and reliability are paramount.
S71914 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| C | 15° Contact Angle | Optimized balance between radial and axial load capacity. |
| D | Enhanced Internal Design | Increased load rating and optimized internal geometry for superior performance. |
| P4A | P4 (ABEC-7) Tolerance Class | Guarantees extremely tight dimensional and running accuracy for high-precision applications. |
S71914 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row design with a 15° contact angle and enhanced internal geometry provides excellent resistance to deformation under combined loads, ensuring stable operation and long service life.
- High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to the high limiting speed of 13,000 rpm. The bearing is pre-lubricated for immediate operation.
- Precision and Accuracy: Manufactured to P4 tolerance class with precise raceway and ball geometry, this bearing ensures minimal runout and vibration, which is critical for high-precision spindles.
- Sealed and Lubricated: The sealed design protects against contamination and retains lubricant, offering a maintenance-free solution within its specified operating range.
S71914 CD/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery requiring high rotational accuracy and speed, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Grinding Equipment
- High-Frequency Motors
- Medical and Dental Equipment Spindles
- Aerospace Instrumentation
