S7007 CE/P4ADGB Bearing Product Overview & Core Advantages
The S7007 CE/P4ADGB is a super-precision angular contact ball bearing designed for the most demanding applications. As a universal matchable (SU) bearing supplied in a pre-set duplex pair, it is engineered to provide exceptional rotational accuracy, high system rigidity, and reliable performance under combined loads. Its P4A tolerance class and light preload (Class B) make it an ideal choice for high-speed spindles and other precision machinery where minimal runout and thermal stability are critical.
S7007 CE/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| S7007 | Basic bearing series and size designation (35mm bore, 62mm OD, 28mm width). |
| CE | Indicates a 15° contact angle, optimized for high-speed operation and moderate axial loads. |
| P4A | Denotes a super-precision tolerance class with enhanced running accuracy requirements. |
| DGB | Specifies a universal matchable (SU) duplex set with light preload (Class B), ready for installation as a pre-adjusted pair. |
S7007 CE/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex pair arrangement creates a rigid bearing system capable of supporting significant combined radial and axial loads from both directions, enhancing machine tool stability.
- Super-Precision Performance: Manufactured to P4A tolerance standards, this bearing ensures extremely low vibration and minimal runout, which is essential for achieving superior surface finishes in machining operations.
- Optimized High-Speed Capability: The 15° contact angle and phenolic resin cage work in concert to reduce centrifugal forces and friction, enabling a high limiting speed of 56,000 rpm.
- Ready-to-Install Matched Set: Supplied as a universal matchable pair (SU) with a light preload, it simplifies mounting, eliminates internal clearance, and ensures immediate, precise performance out of the box.
S7007 CE/P4ADGB Bearing Typical Application Areas
This bearing is specifically engineered for high-performance applications, including:
- Machine Tool Spindles (CNC machining centers, grinding spindles)
- High-Frequency Motors
- Precision Robotic Drives
- Aerospace & Defense Instrumentation
- Medical & Dental Equipment Spindles
