S7006 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7006 CD/P4ADGA is a precision double-row angular contact ball bearing engineered for applications requiring exceptional rotational accuracy and rigidity. Designed with Extra light preload (Class A) and manufactured to P4A tolerance class, this bearing delivers superior running precision. Its double-row design provides high rigidity and the capability to support combined loads (radial and bidirectional axial loads) simultaneously, making it an ideal compact solution for high-performance machinery where space and reliability are critical.
S7006 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7006 | Basic bearing designation (30mm bore, 55mm OD, 26mm width) |
| CD | Contact angle of 15° |
| P4A | High precision tolerance class (superior to ABEC 7) |
| DGA | Universal Matchable (SU) arrangement - bearings are supplied as a matched set of 2 for optimal performance |
S7006 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact configuration and 15° contact angle provide exceptional stiffness, enabling the bearing to handle significant combined radial and axial loads from both directions.
- Precision Performance: Manufactured to P4A tolerance class with extra light preload ensures minimal runout and vibration, critical for high-speed applications.
- Optimized High-Speed Operation: The phenolic cage offers excellent strength-to-weight ratio, contributing to the high limiting speed of 100,500 rpm with reduced centrifugal forces.
- Sealed & Pre-lubricated: Factory-sealed and pre-lubricated with grease provides maintenance-free operation and protects against contamination throughout its service life.
- Universal Matchability: Supplied as a universally matchable set (SU), allowing for flexible mounting arrangements and simplified installation while maintaining preload consistency.
