S7014 CD/P4ADBA Bearing Product Overview & Core Advantages
The S7014 CD/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability and can accommodate combined radial and axial loads from both directions. Manufactured to P4A tolerance class, it ensures minimal runout and is ideal for high-speed, high-precision machinery requiring maximum operational reliability and long service life.
S7014 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Basic bearing series, indicating a 70mm bore, 110mm OD, and 40mm width. |
| C | 15° contact angle. |
| D | Duplex back-to-back (DB) arrangement. |
| P4A | High-precision tolerance class (superior to ABEC 7). |
| DB | Duplex Back-to-Back preload designation. |
| A | Extra light preload classification. |
S7014 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) configuration creates a wide, rigid support system that effectively resists overturning moments, making it ideal for applications requiring high shaft positioning accuracy.
- Superior Load Capacity: Engineered with a 15° contact angle, this bearing is optimized to handle significant combined loads (radial and axial loads acting simultaneously).
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the grease lubrication and precision-ground components contribute to a high limiting speed of 22,000 rpm.
- Exceptional Precision: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring smooth, quiet, and vibration-free operation.
- Sealed & Pre-lubricated: The sealed design protects against contamination and retains lubricant, while the factory-applied grease provides reliable operation across a temperature range of -30°C to 110°C.
S7014 CD/P4ADBA Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles for CNC milling, grinding, and turning centers.
- High-Frequency Spindles in PCB drilling and routing machines.
- Precision Gearboxes and transmission systems.
- Industrial Pumps and Compressors requiring high-speed and high-rigidity support.
- Robotic Arm Joints and Rotary Axes.
