S7012 CB/HCP4ADGA Bearing Product Overview & Core Advantages
The S7012 CB/HCP4ADGA is a super-precision double row angular contact ball bearing designed for the most demanding applications. Engineered to simultaneously handle combined radial and axial loads from both directions, it offers exceptional rotational accuracy and rigidity. Its compact design, featuring ceramic balls and a phenolic cage, is optimized for high-speed operation and superior performance in critical machinery, ensuring maximum reliability and long service life.
S7012 CB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CB | Universal Matchable (SU) bearing with specific internal clearance and preload | Allows for flexible mounting arrangements in pairs or sets without selective matching. |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Reduced weight, lower friction, higher speed capability, and extended service life. |
| P4A | Tolerance class equivalent to ABEC 7 / ISO P4 with additional running accuracy requirements. | Guarantees exceptional running accuracy and low vibration for ultra-precise applications. |
| DGA | Contact angle of 15° | Optimized for carrying significant axial loads in addition to radial loads. |
S7012 CB/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to support substantial combined loads (radial and bidirectional axial loads) effectively.
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a robust phenolic resin cage significantly reduces centrifugal forces and friction, enabling a high limiting speed of 31,000 rpm.
- Exceptional Precision: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for maintaining accuracy in high-precision spindles.
- Pre-Lubricated & Sealed: The bearing comes sealed and pre-lubricated with grease, offering protection against contamination and providing maintenance-free operation within its specified temperature range.
S7012 CB/HCP4ADGA Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications where speed, accuracy, and reliability are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Aerospace & Defense: Gyroscopes, radar systems, and auxiliary power units.
