7000 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7000 CE/P4ADGA is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing, it can be paired in any combination to create preloaded sets, delivering superior rigidity and precise shaft positioning. Its P4A tolerance class ensures extremely tight dimensional and running accuracy, making it ideal for high-precision machinery. The bearing is pre-lubricated and features an open design optimized for controlled lubrication systems.

| Code Segment | Technical Meaning |
|---|---|
| 7000 CE | Basic bearing series with 15° contact angle |
| P4A | High precision tolerance class exceeding ABEC 7 |
| DGA | Universal matchable (SU) designation for flexible mounting configurations |
7000 CE/P4ADGA Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with extremely tight dimensional controls (±0.004mm bore/OD tolerance) for exceptional running accuracy and minimal vibration.
High-Speed Capability: Features a phenolic resin cage that reduces centrifugal forces and friction, enabling operation at limiting speeds up to 185,000 rpm.
Universal Matching Design: As a universal matchable (SU) bearing, it can be mounted in any combination (face-to-face, back-to-back, or tandem) to create preloaded sets that provide optimal stiffness and accommodate combined loads.
Superior Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability and consistent performance under demanding conditions.
