7016 CDTP/P4B Bearing Product Overview & Core Advantages
The 7016 CDTP/P4B is a single-row angular contact ball bearing designed for applications demanding high precision and superior rotational accuracy. Engineered to P4 (ABEC-7) tolerance class, this bearing excels at carrying combined loads, particularly handling significant axial loads in one direction while supporting radial loads. Its 15° contact angle optimizes it for high-speed operation, making it ideal for precision spindles and other high-performance machinery requiring exceptional rigidity and minimal runout.
7016 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Standard bearing series designation, indicating a metric angular contact bearing with an 80mm bore and 125mm outside diameter. |
| C | Specifies a 15° contact angle, optimized for high-speed performance. |
| DTP | Indicates a specific internal design and preload class for enhanced rigidity and precise shaft positioning. |
| P4 | Denotes the tolerance class (equivalent to ABEC-7), ensuring extremely tight dimensional and running accuracy. |
| B | Typically indicates the bearing is supplied with a specific, high-performance lubricant suitable for the specified temperature range. |
7016 CDTP/P4B Bearing Structural Features & Performance Benefits
High Rigidity and Precision: Manufactured to P4 tolerance standards with a phenolic cage, this bearing offers exceptional dimensional stability and low vibration, crucial for applications like machine tool spindles. The phenolic cage contributes to smooth operation at high speeds.
Optimized Load Capacity: The 15° contact angle and robust construction using chrome steel for both rings and balls enable it to handle high radial dynamic load ratings of 14,625 lbf and axial loads simultaneously.
Superior High-Speed Performance: The combination of the lightweight phenolic cage, optimized internal geometry, and preload allows for a high limiting speed of 10,000 rpm, making it suitable for demanding high-speed applications.
Ready for Service: The bearing is pre-lubricated and features an open seal type, allowing for custom lubrication regimes tailored to specific operational needs and environments within its temperature range of -30°C to 110°C.
