S7014 CDGB/P4A Bearing Product Overview & Core Advantages
The S7014 CDGB/P4A is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. As a single bearing from a Universal Matchable (SU) set, it is engineered to handle combined loads efficiently, supporting significant radial loads and axial loads in one direction. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other precision machinery where minimal runout and vibration are critical. The combination of a light preload (Class B) and optimized internal geometry contributes to smooth operation and extended service life.
S7014 CDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Basic bearing series designation, indicating a 70mm bore, 110mm OD, and 20mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed applications and axial load capacity. |
| DGB | Indicates a Universal Matchable (SU) bearing. Two bearings can be paired in a back-to-back (DB) arrangement to handle moment loads and bidirectional axial loads. |
| P4A | Denotes a high-precision tolerance class, superior to ABEC-7, ensuring extremely tight dimensional and running accuracy for demanding applications. |
S7014 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 15° contact angle provides robust support for combined radial and axial loads. When used in a matched set, the arrangement significantly increases system rigidity and moment load capacity.
- Superior High-Speed Performance: The phenolic resin cage offers excellent strength-to-weight ratio and low friction, contributing to a high limiting speed of 22,000 rpm. This makes the bearing suitable for high-speed spindles.
- Precision Engineering: Manufactured to P4A tolerance standards with tight bore, outer diameter, and width tolerances, this bearing guarantees minimal vibration and precise shaft positioning.
- Sealed and Pre-Lubricated: The bearing is sealed to protect against contamination and is pre-lubricated with grease, offering a maintenance-free solution within its specified temperature range of -30°C to 110°C.
S7014 CDGB/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
