71914 CD/HCP4A Bearing Product Overview & Core Advantages
The 71914 CD/HCP4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining characteristic is the 15° contact angle, optimized to support significant combined loads—handling both radial and axial forces simultaneously. Manufactured to P4 (ABEC-7) tolerance class, it guarantees exceptional running accuracy and rotational precision. The use of a phenolic resin cage and ceramic balls contributes to reduced weight, lower friction, and superior performance at high rotational speeds, making it an ideal component for demanding, precision machinery.
71914 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 71914 | Standard bearing series designation, indicating the bearing dimensions (70mm bore, 100mm OD, 16mm width). |
| C | Specifies a 15° contact angle. |
| D | Indicates the bearing is part of a matched arrangement for preload. |
| HC | Signifies the use of hybrid ceramic balls (Silicon Nitride). |
| P4 | Denotes the P4 (ABEC-7) tolerance class for ultra-high precision. |
| A | Indicates that the bearing has a specific preload level applied. |
71914 CD/HCP4A Bearing Structural Features & Performance Benefits
High-Speed & High-Rigidity Performance: The combination of a lightweight phenolic cage and low-density ceramic balls minimizes centrifugal forces, enabling the bearing to achieve a high limiting speed of 24,000 rpm. This design ensures exceptional dynamic stability and rigidity.
Superior Load Capacity: The 15° contact angle is engineered to efficiently handle combined radial and axial loads. With a dynamic load rating of 7762 lbf and a static load rating of 7650 lbf, it provides reliable performance under strenuous operating conditions.
Precision & Longevity: Manufactured to P4 precision class with tight dimensional tolerances, this bearing ensures minimal vibration and high running accuracy. The open seal type allows for optimized lubrication management, which is critical for maintaining performance in high-speed, precision bearing applications.
