S7014 CDGA/P4A Bearing Product Overview & Core Advantages
The S7014 CDGA/P4A is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Engineered to a P4A tolerance class, it offers extremely tight dimensional and running accuracy. Its 15° contact angle and Extra Light (Class A) preload make it ideally suited for handling combined loads (radial and axial) simultaneously, providing high system rigidity and minimal runout. The phenolic cage and universal matching (SU) designation enable stable operation at high speeds and facilitate simplified bearing arrangement design.
S7014 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Super-precision bearing series with 70mm bore diameter. |
| C | 15° nominal contact angle. |
| DG | Universal Matchable (SU) bearing. Two bearings can be paired in a back-to-back (DB) or face-to-face (DF) arrangement. |
| A | Extra Light preload (Class A). |
| P4A | High-precision tolerance class, superior to ABEC 7/ISO P4. |
S7014 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and preload provide high system stiffness, effectively supporting combined radial and axial loads. With a dynamic load rating of 11700 lbf, it ensures reliable performance under demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces and ensures stable guidance of the balls, contributing to a high limiting speed of 22,000 rpm. The optimized internal geometry reduces friction and heat generation.
- Exceptional Precision: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration, which is critical for applications requiring ultra-high rotational accuracy.
- Universal Matching: The Universal Matchable (SU) feature allows for simplified mounting of two bearings in pre-determined configurations (DB or DF) without the need for selective assembly, reducing installation time and complexity.
S7014 CDGA/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-precision, high-speed machinery, including:
- Machine Tool Spindles
- High-Frequency Machining Centers
- Precision Grinding Spindles
- Industrial High-Speed Motors
- Aerospace Gyroscopes and Instrumentation
