S7006 CD/P4ATGB Bearing Product Overview & Core Advantages
The S7006 CD/P4ATGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-set group of three, it enables simplified installation and optimal performance in preloaded configurations. Its P4A tolerance class ensures ultra-precise running, making it ideal for high-speed spindles and other high-precision machinery. The phenolic cage and sealed design contribute to reliable operation under demanding conditions.

S7006 CD/P4ATGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and universal matching capability allow the bearing set to accommodate combined loads (radial and axial) simultaneously. The preload (Light / Class B) enhances system stiffness and minimizes axial play.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, enabling stable operation up to the limiting speed of 100,500 rpm. The 15° contact angle is optimized for high-speed applications.
- Precision & Longevity: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration. The integral seals protect against contamination, and the pre-greased design ensures immediate, maintenance-free operation within a temperature range of -30°C to 110°C.
S7006 CD/P4ATGB Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications requiring precision and speed, such as:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- High-Speed Pumps and Compressors
- Aerospace & Defense Instrumentation
