7001 CE/P4ADBB Bearing Product Overview & Core Advantages
The 7001 CE/P4ADBB is a duplex back-to-back matched pair of metric precision angular contact ball bearings. This pre-configured duplex set is engineered to provide exceptional system rigidity and precise rotational accuracy. The Light preload (Class B) ensures minimal deflection under operational stresses, making it ideal for applications demanding high precision and smooth operation. Its compact design combines a 12 mm bore with a 28 mm outside diameter, offering a space-saving solution for high-rigidity mounting arrangements.
7001 CE/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a duplex bearing set with a specific contact angle and preload. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy for the inner and outer rings. |
| DBB | Specifies the Duplex Back-to-Back arrangement, which provides high moment stiffness. |
7001 CE/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Moment Load Capacity: The back-to-back (DB) arrangement creates a wide effective spread, significantly increasing the system's resistance to moment loads and tilting moments, resulting in superior operational stability.
- Optimized for Combined Loads: The 15° contact angle is engineered to efficiently handle combined radial and axial loads simultaneously.
- Precision & Speed: The P4A tolerance class ensures minimal runout and vibration. Combined with the lightweight, high-strength phenolic resin cage, the bearing supports a high limiting speed of 100,000 rpm, making it suitable for high-speed applications.
- Material & Lubrication: Manufactured from chrome steel for both rings and balls, ensuring durability and long service life. The bearings are pre-lubricated for immediate use upon installation.
7001 CE/P4ADBB Bearing Typical Application Areas
This precision duplex bearing set is ideally suited for high-performance machinery and systems, including:
- Machine Tool Spindles
- High-Speed Grinding Spindles
- Precision Gearboxes
- Medical and Dental Handpieces
- Robotic Arm Joints and Servo Motors
