7015 CE/P4ADGA Bearing Product Overview & Core Advantages
The 7015 CE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle is optimized for handling combined loads, efficiently supporting both radial and axial forces. The universal matchable (SU) design allows for flexible mounting in various preload configurations, making it an ideal choice for high-rigidity spindles and precision machinery where reliability is paramount.
7015 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7015 | Series designation indicating a metric, angular contact bearing with a 75mm bore and 115mm outside diameter. |
| CE | Indicates a 15° contact angle, optimized for high-speed operation and combined load capacity. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy and dimensional control. |
| DGA | Signifies the bearing is lubricated and supplied as part of a universally matchable (SU) pair. |
7015 CE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and phenolic cage provide excellent stability, enabling the bearing to handle significant combined radial and axial loads with a dynamic load rating of 9518 lbf and static load rating of 9675 lbf.
- Superior High-Speed Performance: The 15° contact angle and lightweight phenolic cage contribute to a high limiting speed of 24,000 rpm, making it suitable for high-speed spindle applications.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls on the bore, outside diameter, and width, ensuring consistent performance in precision assemblies.
- Universal Matching Capability (SU): Designed to be paired with a second bearing for universal matchable arrangements, allowing for simplified installation and optimized preload settings (in this case, Extra Light / Class A preload).
7015 CE/P4ADGA Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring precision and rigidity.
