S7006 CB/P4ADGA Bearing Product Overview & Core Advantages
The S7006 CB/P4ADGA is a precision double-row angular contact ball bearing designed for applications demanding exceptional rigidity and running accuracy. Engineered with Extra light preload (Class A) and P4A tolerance class, it delivers superior rotational precision and stability. Its double-row design enables it to support combined loads (radial and bidirectional axial loads) simultaneously, making it an ideal, compact solution for high-speed spindles and precision machinery where high reliability is paramount.
S7006 CB/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CB | Specific internal design and clearance for universal matching. |
| P4A | Denotes a high-precision tolerance class with restricted width tolerance, ensuring exceptional dimensional and running accuracy. |
| DGA | Indicates the bearing is sealed and pre-lubricated with a specific high-performance grease. |
S7006 CB/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact design provides significantly higher rigidity than single-row bearings, offering robust support against complex combined loads and moment loads.
- Precision & High-Speed Performance: The P4A tolerance class and phenolic cage contribute to smooth operation and low vibration at high speeds, with a limiting speed of 100,500 rpm. The optimized 15° contact angle provides an excellent balance between radial and axial load capacity.
- Maintenance-Free Operation: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is designed for long-term, maintenance-free service within its specified temperature range.
- Universal Matchability (SU): This bearing is universally matchable, allowing for flexible mounting arrangements (back-to-back, face-to-face, or tandem) to achieve specific preload and stiffness characteristics without selective assembly.
S7006 CB/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications including:
- Machine Tool Spindles
- High-Speed Grinding Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotic Arms and Precision Positioning Systems
