7001 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7001 CE/P4ADGA is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing supplied in a preloaded pair, it is engineered to provide superior axial and radial rigidity. Its P4A tolerance class and extra light preload (Class A) make it ideal for high-precision spindles and other critical machinery where minimal runout and high dynamic stability are required.

| Code Segment | Technical Meaning |
|---|---|
| 7001 | Basic bearing series with 12mm bore, 28mm OD |
| CE | Enhanced internal design for improved high-speed performance |
| P4A | Super precision tolerance class with specific running accuracy requirements |
| DGA | Universal matchable bearing pair with preload |
7001 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance class with extremely tight dimensional control (±0.004mm on bore and OD) ensures minimal vibration and superior running accuracy.
Optimized High-Speed Design: The CE-enhanced internal geometry combined with phenolic resin cage reduces friction and enables operation at limiting speeds up to 100,000 rpm.
Superior Rigidity: As a universal matchable pair with preload, these bearings provide exceptional axial and radial stiffness, making them ideal for applications requiring high dynamic stability.
Precision Load Capacity: With a 15° contact angle and dynamic load rating of 1170 lbf, the bearing efficiently handles combined radial and axial loads in high-speed applications.
