S7007 CD/P4ADGB Bearing Product Overview & Core Advantages
The S7007 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, this bearing excels in high-speed operations with a limiting speed of 41,000 rpm. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, while the sealed construction and pre-lubrication ensure long-term, maintenance-free performance. It is ideally suited for handling combined radial and axial loads simultaneously, making it a cornerstone for high-performance mechanical systems.
S7007 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S7007 | Basic bearing series designation | Indicates a high-precision, 35mm bore angular contact bearing. |
| CD | Contact angle of 15° and universal matchable (SU) design | Optimized for handling combined loads; allows for flexible mounting in pairs (back-to-back, face-to-face, or tandem). |
| P4A | High precision tolerance class | Guarantees extremely tight dimensional and running accuracy for superior performance in demanding applications. |
| DGB | Sealed on both sides and pre-lubricated with grease | Provides effective contamination exclusion and long-lasting, maintenance-free operation. |
S7007 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized internal geometry and 15° contact angle provide excellent resistance to deformation under combined loads, ensuring stable shaft support and positioning accuracy.
- Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, while the precision-ground chrome steel components and optimized internal clearance contribute to the high limiting speed of 41,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with extremely tight bore, OD, and width tolerances, this bearing guarantees minimal runout and vibration for ultra-smooth operation.
- Maintenance-Free Operation: The integral contact seals effectively retain grease and exclude contaminants, enabling reliable performance across a wide temperature range (-30°C to 110°C) without re-lubrication.
