S7009 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The S7009 ACDGA/HCP4A is a high-precision double row angular contact ball bearing engineered for exceptional performance in demanding applications. This sealed bearing features a universal matching design (SU), allowing for flexible mounting configurations in sets. Its core advantages include the ability to handle combined radial and axial loads simultaneously, superior running accuracy due to its P4A tolerance class, and high-speed capability enabled by its phenolic cage and ceramic balls. The compact design and pre-lubrication make it an ideal, high-rigidity solution for high-reliability machinery.
S7009 ACDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7009 | Basic bearing series and size designation (45mm bore, 75mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| DGA | Double Row design with universal matching (SU). |
| HCP4A | Indicates a set of 3 bearings supplied as a matched set (H), with a phenolic cage (C), and manufactured to P4A super-precision tolerance class. |
S7009 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to support significant combined loads from multiple directions, making it exceptionally stable under complex loading conditions.
- Superior High-Speed Performance: The lightweight phenolic cage and low-friction ceramic balls significantly reduce centrifugal forces and operating temperatures, allowing for a high limiting speed of 46,000 rpm. This makes it an ideal high-speed bearing.
- Precision & Longevity: Manufactured to the stringent P4A tolerance class, this bearing ensures minimal runout and vibration for ultra-smooth operation. The sealed design and pre-applied grease lubrication offer protection against contamination and provide long-term, maintenance-free service within a wide temperature range (-30°C to 110°C).
- Universal Matching: As a Universal Matchable (SU) bearing supplied in a set of three, it allows for flexible mounting arrangements (e.g., back-to-back, face-to-face) to optimize preload and system rigidity without selective assembly.
