7000 CEGA/P4A Bearing Product Overview & Core Advantages
The 7000 CEGA/P4A is a single-row angular contact ball bearing engineered for applications requiring high precision and superior running accuracy. Positioned in the P4A tolerance class, it delivers exceptional dimensional stability and rotational precision. Its 15° contact angle is optimized to handle combined loads, efficiently supporting significant axial loads in one direction alongside radial loads. The phenolic cage and universal matching designation (SU) enable high-speed operation and facilitate precise bearing arrangements. This bearing comes pre-lubricated and is ideal for machine tool spindles, precision instruments, and other high-performance rotational systems.
7000 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7000 | Basic series designation for a metric, single-row angular contact ball bearing. |
| CE | Designates a 15° contact angle and enhanced internal design for optimal performance. |
| GA | Indicates a specific internal clearance and preload group for extra light preload (Class A). |
| P4A | Specifies the tolerance class, denoting very high precision levels for dimensional and running accuracy. |
7000 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4A tolerance class standards, this bearing ensures minimal runout and exceptional dimensional accuracy, providing stable and rigid support for shafts.
- Optimized Load Capacity: The 15° contact angle is engineered to effectively support combined loads, offering high thrust capacity in one direction while maintaining excellent radial load performance.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 95,000 rpm, making it suitable for high-speed spindle applications.
- Universal Matchability (SU): Designed as a universally matchable bearing, it can be paired with another identical bearing in a back-to-back or face-to-face arrangement to achieve specific stiffness and preload requirements without selective mounting.
- Pre-Lubricated & Ready-to-Use: The bearing is supplied with grease, covering a standard operating temperature range, ensuring immediate installation and initial operation.
