7015 CEGA/P4A Bearing Product Overview & Core Advantages
The 7015 CEGA/P4A is a single row angular contact ball bearing designed for high-precision and high-speed applications. Engineered to Universal Matchable (SU) standards, it allows for precise preload control when mounted in sets. Its P4A super precision tolerance class and extra light preload (Class A) ensure exceptional running accuracy and minimal vibration, making it ideal for demanding applications requiring superior rotational performance and rigidity.
7015 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7015 | Standard bearing series designation, defining the bearing dimensions (75mm bore, 115mm OD, 20mm width). |
| CE | Designates a 15° contact angle, optimized for handling high axial loads in one direction combined with radial loads. |
| GA | Indicates the bearing is supplied with a preload classification (Extra Light / Class A). |
| P4A | Specifies the tolerance class, denoting super precision levels for high-accuracy applications. |
7015 CEGA/P4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The phenolic resin cage offers low friction and high strength, contributing to the high limiting speed of 24,000 rpm. This lightweight cage is ideal for demanding high-speed spindle applications.
- Superior Rigidity and Load Capacity: The 15° contact angle and high-grade chrome steel construction provide excellent rigidity and the ability to support significant combined radial and axial loads.
- Precision Performance: Manufactured to P4A tolerance class with a universal matching (SU) designation, this bearing ensures minimal runout and consistent performance when used in preloaded sets, delivering exceptional rotational accuracy.
- Optimized for Matched Sets: Designed as a Universal Matchable (SU) bearing, it can be mounted in sets of two or more (typically 3) to achieve defined preload levels, enhancing system stiffness and accuracy.
7015 CEGA/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance machinery where speed, accuracy, and rigidity are paramount. Key applications include:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
