7016 CD/HCP4ADBB Bearing Product Overview & Core Advantages
The 7016 CD/HCP4ADBB is a metric duplex pair of precision angular contact ball bearings designed for applications demanding exceptional rotational accuracy and rigidity. This back-to-back (DB) matched arrangement is preloaded to Light / Class B specifications, providing superior stability and minimizing axial and radial runout. Its construction, featuring ceramic balls and a phenolic cage, is optimized for high-speed operation up to 28,000 rpm, while effectively handling combined loads. This bearing set is engineered for high reliability in the most demanding precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD). |
| C | Specifies a 15° contact angle, optimized for high-speed performance and moderate axial load capacity. |
| D | Indicates the bearings are supplied as a duplex pair. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride), which reduce friction, heat generation, and wear, enabling higher speeds. |
| P4A | Denotes an ultra-high precision tolerance class (superior to ABEC 7), ensuring minimal dimensional and running inaccuracies. |
| DB | Specifies the Back-to-Back mounting arrangement, which provides high moment rigidity and excellent stability under complex loads. |
| B | Indicates the Light preload class, which minimizes deflection without generating excessive heat. |
7016 CD/HCP4ADBB Bearing Structural Features & Performance Benefits
High Rigidity and Stability: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists moment loads and shaft misalignment, making it ideal for precision spindles.
Superior High-Speed Capability: The combination of low-density ceramic balls and a lightweight, robust phenolic cage significantly reduces centrifugal forces, enabling stable operation at the limiting speed of 28,000 rpm.
Enhanced Load Capacity: Designed as angular contact bearings, this set can accommodate combined radial and axial loads simultaneously. The dynamic and static load ratings of 23,850 lbf and 27,450 lbf, respectively, ensure long service life under demanding conditions.
Precision Engineering: Manufactured to P4A tolerance class with tight bore and outside diameter tolerances, this bearing guarantees exceptional running accuracy, low vibration, and consistent performance.
