S7008 FE/P4ADBA Bearing Product Overview & Core Advantages
The S7008 FE/P4ADBA is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a duplex back-to-back (DB) matched set, it delivers superior performance in handling combined loads, including significant radial and bidirectional axial forces. Manufactured to the stringent P4A tolerance class, this bearing offers high running accuracy and is preloaded for extra-light preload (Class A), ensuring minimal deflection and optimal rigidity in high-speed operations. Its compact design and phenolic cage contribute to its status as a high-performance high-speed bearing.
S7008 FE/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| FE | Indicates a duplex bearing set with a specific preload and matching arrangement. |
| P4A | Denotes the tolerance class, signifying very high precision levels for both dimensional and running accuracy. |
| DB | Specifies the Back-to-Back arrangement of the matched set, which provides high moment rigidity. |
| A | Specifies the Extra Light Preload class, ideal for high-speed applications requiring minimal friction. |
S7008 FE/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity and Stability: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively resists moment loads and shaft deflection, ensuring precise shaft positioning and high rigidity.
Superior Load Capacity: With a contact angle of 18°, this bearing is engineered to handle substantial combined loads, offering excellent performance for both radial and bidirectional axial forces.
Optimized High-Speed Performance: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces, reduced friction, and a high limiting speed of 41,000 rpm. The extra-light preload further minimizes heat generation at high velocities.
Sealed and Pre-Lubricated: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is ready for immediate installation, offering long-term, maintenance-free operation within its specified temperature range.
S7008 FE/P4ADBA Bearing Typical Application Areas
The S7008 FE/P4ADBA is ideally suited for high-precision, high-speed machinery where accuracy and rigidity are paramount. Key applications include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
