7002 CE/P4A Bearing Product Overview & Core Advantages
The 7002 CE/P4A is a single-row angular contact ball bearing engineered for high-precision applications. Designed to accommodate combined loads (radial and axial loads in one direction), this bearing features a 15° contact angle and is supplied with a light preload (CE) for enhanced rigidity and rotational accuracy. Manufactured to P4 (ABEC-7) tolerance class, it delivers exceptional running accuracy and is ideal for applications demanding high speeds and superior performance.
7002 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| CE | Light Preload | Reduces axial and radial play, increases system rigidity, and improves rotational accuracy. |
| P4 | Tolerance Class (ABEC-7) | Guarantees ultra-precise dimensions and runout for high-performance applications. |
| A | 30° Contact Angle (Standard for this series) | Optimized for carrying significant axial loads in one direction. |
7002 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The light preload (CE) eliminates internal clearance, providing superior system stiffness and precise shaft positioning, which is critical for high-speed operation.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently support combined radial and axial loads, making it suitable for complex loading conditions.
- High-Speed Capability: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to a high limiting speed of 106,000 rpm.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability, wear resistance, and a long service life under demanding conditions.
7002 CE/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for applications requiring high speed, accuracy, and rigidity, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Medical and Dental Handpieces
- High-Precision Robotics
