7000 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 7000 CE/HCP4ADGA is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and speed. This universal matchable bearing is designed to accommodate combined loads, offering superior performance in high-rigidity systems. Its construction with ceramic balls and a phenolic cage enables outstanding high-speed capabilities and thermal stability, making it an ideal choice for precision machinery where reliability is paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7000 | Basic series designation for angular contact ball bearings |
| CE | Contact angle of 15° |
| HC | Hybrid ceramic construction (ceramic balls with steel rings) |
| P4A | High precision tolerance class (equivalent to ABEC 7) |
| DGA | Universal matchable bearing designation (can be mounted in any combination) |
7000 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and silicon nitride ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds (185,000 rpm) and extended service life.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore and OD tolerance: -0.004mm to 0), ensuring consistent performance and precise running accuracy.
Optimized Cage Design: The phenolic resin cage provides excellent strength-to-weight ratio, reduced centrifugal forces, and superior lubrication retention at high speeds.
Universal Matching Capability: As a Universal Matchable (SU) bearing, these bearings can be mounted in any combination (back-to-back, face-to-face, or tandem) without preload variation, simplifying installation and maintenance.
Combined Load Capacity: The 15° contact angle enables efficient handling of both radial and axial loads, making it suitable for complex loading conditions.
