7000 CE/HCP4ADT Bearing Product Overview & Core Advantages
The 7000 CE/HCP4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This duplex tandem (DT) arrangement bearing set delivers superior high rigidity and axial load capacity in one direction. Manufactured to P4A tolerance class, it ensures ultra-precise rotational accuracy. The combination of a ceramic ball and phenolic cage construction enables outstanding high-speed performance, making it ideal for machine tool spindles and other precision machinery.
7000 CE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates 15° contact angle for optimal axial load capacity. |
| HC | Refers to Hybrid Ceramic construction (steel rings with ceramic balls). |
| P4A | Denotes high precision tolerance class for superior running accuracy. |
| DT | Signifies Duplex Tandem arrangement, where two bearings are mounted to increase axial load capacity in one direction. |
7000 CE/HCP4ADT Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of ceramic balls with steel rings reduces centrifugal forces, lowers operating temperature, and significantly extends service life at high speeds. This construction provides excellent electrical insulation properties.
High Rigidity & Load Capacity: The duplex tandem arrangement creates an exceptionally rigid bearing system capable of handling heavy combined loads, particularly substantial axial loads in one direction.
Superior High-Speed Performance: The lightweight phenolic cage and ceramic balls work together to achieve an impressive limiting speed of 185,000 rpm, making these bearings ideal for ultra-high-speed applications.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on bearing dimensions (10mm bore, 26mm OD, 16mm width), ensuring precise fitment and minimal runout.
