7000 CE/HCP4ADGC Bearing Product Overview & Core Advantages
The 7000 CE/HCP4ADGC is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This universal matchable bearing features a 15° contact angle and a Moderate (Class C) preload, making it ideal for arrangements that must support combined radial and axial loads with minimal deflection. Its construction with a phenolic cage and ceramic balls contributes to lower friction, higher limiting speeds, and extended service life, establishing it as a superior choice for high-performance machinery.
7000 CE/HCP4ADGC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CE | Indicates the use of ceramic balls, which reduce weight, lower friction, and allow for higher operating speeds. |
| HC | Refers to the phenolic (Hybrid Composite) cage, offering high strength and excellent performance at high speeds. |
| P4A | Denotes an ultra-precision tolerance class, ensuring extremely tight dimensional and running accuracy for critical applications. |
| DGC | Specifies the bearing is lubricated and supplied as part of a universally matchable set (SU) of two bearings. |
7000 CE/HCP4ADGC Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The angular contact design and Moderate preload provide superior stiffness, enabling the bearing to effectively handle combined loads with high precision and minimal elastic deformation.
Enhanced High-Speed Performance: The combination of a lightweight phenolic cage and low-density ceramic balls significantly reduces centrifugal forces, allowing for a very high limiting speed of 185,000 rpm.
Precision and Longevity: Manufactured to P4A tolerance class, this bearing guarantees exceptional running accuracy. The open seal type facilitates optimal lubrication management in controlled environments, while the ceramic balls offer superior corrosion and wear resistance.
