7014 CD/HCP4A Bearing Product Overview & Core Advantages
The 7014 CD/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial loads), this single bearing features a 15° contact angle optimized for high-speed operation. Its construction with ceramic balls and a phenolic cage contributes to lower friction, higher limiting speeds, and extended service life, making it an ideal choice for high-rigidity and high-reliability precision machinery.
7014 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7014 | Basic bearing series, indicating a bore diameter of 70 mm, outside diameter of 110 mm, and width of 20 mm. |
| CD | Internal design designation for a specific contact angle (15°) and optimized internal geometry. |
| HC | Indicates the use of Hybrid Ceramic components (ceramic balls with steel rings). |
| P4 | Specifies the tolerance class P4 (ABEC-7), denoting very high dimensional and running accuracy. |
| A | Indicates that the bearing is supplied with a specific preload for enhanced stiffness. |
7014 CD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The angular contact design combined with a factory-set preload ensures high system stiffness, minimizing deflection under load for superior positioning accuracy.
- Superior High-Speed Performance: The lightweight phenolic resin cage and low-density ceramic balls reduce centrifugal forces, enabling a high limiting speed of 22,000 rpm.
- Extended Service Life & Reliability: Hybrid ceramic construction offers excellent wear resistance, reduced thermal expansion, and the ability to operate effectively within a broad temperature range (-30°C to 110°C).
- Precision Engineering: Manufactured to P4 (ABEC-7) tolerance class with tight dimensional control on the bore diameter, outside diameter, and width for consistent, high-performance operation.
