7014 CD/HCP4ADGB Bearing Product Overview & Core Advantages
The 7014 CD/HCP4ADGB is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered with a universal matchable (SU) design, this bearing can be paired with another identical bearing to form a preloaded duplex set that delivers superior rigidity and precise rotational performance. Its ceramic ball construction and P4A tolerance class make it ideal for high-speed operation and applications where minimal thermal expansion is critical. The bearing is pre-lubricated and capable of handling combined radial and axial loads simultaneously, making it a compact, high-performance solution for precision machinery.
7014 CD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | 15° contact angle and optimized internal design for high-speed performance |
| HC | Hybrid ceramic balls (steel rings with ceramic balls) |
| P4A | High precision tolerance class exceeding ABEC 7 standards |
| DGB | Universal matchable (SU) design for duplex mounting |
7014 CD/HCP4ADGB Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds (22,000 rpm) and extended service life in demanding conditions.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore diameter tolerance: -0.004mm to 0), ensuring consistent high-precision performance and minimal runout.
Universal Matchable Design: The SU arrangement allows two bearings to be mounted in tandem, back-to-back, or face-to-face configurations, providing flexibility in achieving optimal stiffness and load distribution for specific application requirements.
Optimized Internal Geometry: The 15° contact angle and phenolic cage work in harmony to provide excellent high-speed capability while maintaining stability under combined loading conditions.
Pre-Lubricated for Immediate Use: Factory lubricated for immediate installation and operation within the specified temperature range (-30°C to 110°C).
