S7016 CDTP/P4B Bearing Product Overview & Core Advantages
The S7016 CDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to P4 (ABEC-7) tolerance class, it delivers superior running precision. This bearing is preloaded and sealed, making it an ideal, ready-to-install unit for high-speed spindles and other precision machinery where handling combined loads (radial and axial) is critical. Its compact design and high rigidity contribute to enhanced system performance and longevity.
S7016 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7016 | Standard bearing series designation with 80mm bore. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| DT | Indicates a matched pair of bearings in a tandem arrangement (Duplex Tandem), providing high axial rigidity and load capacity in one direction. |
| P4 | Denotes a high-precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration. |
| B | Indicates a preload level (moderate preload), which increases bearing rigidity and positional accuracy. |
S7016 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The duplex tandem (DT) arrangement combines two bearings to significantly enhance axial rigidity and load-carrying capacity in one direction, making it suitable for heavy thrust loads. The 15° contact angle is optimized for supporting substantial combined radial and axial loads.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at the high limiting speed of 10,000 rpm. The bearing is pre-lubricated for immediate operation.
- Exceptional Precision and Durability: Manufactured to P4 precision class with tight dimensional tolerances, this bearing ensures minimal vibration and high running accuracy. Components made from chrome steel provide high fatigue resistance and long service life.
- Sealed and Protected: The sealed design protects the bearing from contamination, retaining lubricant and ensuring reliable, maintenance-free operation in demanding environments.
S7016 CDTP/P4B Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Industrial Pumps and Compressors
- Robotics and Automation: High-accuracy rotary joints and actuators.
