S7209 CDGA/P4A Bearing Product Overview & Core Advantages
The S7209 CDGA/P4A is a high-precision double row angular contact ball bearing designed for applications demanding exceptional rigidity and running accuracy. Engineered with an extra light preload (Class A) and manufactured to P4A tolerance class, this bearing excels in high-speed scenarios while providing robust support for combined radial and axial loads in both directions. Its compact design, sealed construction, and universal matchability make it an ideal solution for high-reliability, precision machinery.
S7209 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CDGA | Universal Matchable bearing set with specific preload and internal clearance | Ensures optimal performance and load distribution when used in pairs; simplifies mounting. |
| P4A | High-Precision Tolerance Class | Guarantees extremely tight dimensional and running accuracy for superior performance in precision applications. |
S7209 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and 15° contact angle provide significantly increased radial and axial stiffness compared to single row bearings, enabling stable operation under combined loads.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the grease lubrication and optimized internal geometry contribute to a high limiting speed of 46,000 rpm.
- Sealed & Pre-lubricated: As a sealed bearing, it is filled with high-quality grease, offering protection against contamination and providing long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
- Precision Engineering: Manufactured from chrome steel and held to the stringent P4A tolerance class, this bearing ensures minimal runout and vibration for ultra-smooth rotation.
