S7014 CD/P4ADT Bearing Product Overview & Core Advantages
The S7014 CD/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This duplex tandem (DT) matched set features a P4A super-precision tolerance class and is preloaded, enabling it to handle significant combined loads (radial and axial) simultaneously. Its compact design, sealed construction, and phenolic cage make it an ideal solution for high-speed, high-reliability machinery where uncompromising performance is critical.
S7014 CD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Basic bearing series designation. |
| CD | Indicates a duplex tandem (DT) matched set of two bearings, designed to be mounted together to increase axial load capacity in one direction. |
| P4A | Denotes a super-precision tolerance class with enhanced running accuracy, suitable for ultra-high-speed applications. |
| Sealed | The bearing is equipped with integral seals, protecting against contamination and retaining lubricant for extended service life. |
| Grease Lubrication | Pre-lubricated with grease, offering a ready-to-install, low-maintenance solution. |
S7014 CD/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex tandem arrangement and 15° contact angle provide superior axial stiffness and enable the bearing set to withstand high combined radial and axial loads.
- Super-Precision Performance: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring extreme positional accuracy.
- Optimized High-Speed Operation: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 22,000 rpm.
- Enhanced Service Life & Reliability: The sealed design effectively excludes contaminants, while the pre-applied grease lubrication operates effectively within a wide temperature range of -30°C to 110°C, ensuring long-term, maintenance-free operation.
S7014 CD/P4ADT Bearing Typical Application Areas
This precision bearing set is ideally suited for:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Gearboxes and High-Frequency Motors
- Industrial Pumps and Compressors
- Aerospace Actuation Systems and Medical Equipment
