S7009 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The S7009 CD/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for exceptional performance in demanding applications. This sealed bearing is designed to simultaneously handle combined loads (radial and bidirectional axial loads) with high reliability. Its universal matchable (SU) design allows for flexible mounting arrangements, while the P4A tolerance class and ceramic balls ensure superior running accuracy and high-speed capability. This combination makes it an ideal solution for applications requiring high rigidity, extended service life, and minimal maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7009 | Basic bearing series and size designation (45mm bore, 75mm OD). |
| CD | Indicates a double row angular contact ball bearing with a 15° contact angle. |
| HC | Refers to the phenolic (resin) cage, which is lightweight and suitable for high-speed operation. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy and dimensional stability. |
| DGA | Signifies the bearing is sealed and pre-lubricated with grease, offering protection from contamination and long-term lubrication. |
S7009 CD/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support significant combined radial and axial loads from both directions, making it exceptionally stable under complex loading conditions.
High-Speed Performance: The combination of a lightweight phenolic cage and ceramic balls significantly reduces centrifugal forces, lowers operating temperatures, and allows for a high limiting speed of 46,000 rpm. This makes it an excellent high-speed bearing.
Precision & Longevity: Manufactured to P4A tolerance class with a 15° contact angle, this bearing delivers ultra-precise rotation. The sealed construction with pre-applied grease lubrication protects against contaminants and ensures reliable, maintenance-free operation throughout its service life.
