S7012 CDGA/P4A Bearing Product Overview & Core Advantages
The S7012 CDGA/P4A is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a single bearing with Universal Matchable (SU) designation, it can be universally paired with other bearings from the same manufacturing lot to form a matched set of up to 4 bearings, ensuring optimal preload and rigidity. Its P4A tolerance class and Extra light preload (Class A) make it ideal for machine tool spindles and other high-precision machinery where minimal friction and maximum running accuracy are critical.
S7012 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| CDGA | Universal Matchable bearing with a 15° contact angle and specific internal radial clearance/preload. | Enables flexible mounting in back-to-back (DB), face-to-face (DF), or tandem (DT) arrangements to achieve the required system rigidity and load capacity. |
| P4A | High-precision tolerance class superior to ABEC 7 (P4). The 'A' suffix often denotes enhanced running accuracy. | Guarantees extremely low vibration and superior rotational accuracy for demanding high-speed applications. |
S7012 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 15° contact angle and robust construction allow the bearing to support significant combined loads (radial and axial). The Universal Matchable (SU) feature ensures that when used in sets, the bearings share loads evenly, enhancing overall system stiffness.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry and grease lubrication contribute to a high limiting speed of 31,000 rpm, making it an excellent high-speed bearing.
- Exceptional Precision & Low Torque: Manufactured to P4A tolerance class with an extra light preload, this bearing delivers minimal running torque and exceptional rotational accuracy, which is critical for precision machining and instrumentation.
- Sealed & Pre-Lubricated: The sealed design protects against contamination, and the factory-applied grease provides reliable lubrication within its specified temperature range of -30°C to 110°C, ensuring long service life.
S7012 CDGA/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: High-accuracy measuring devices and rotary tables.
- High-Frequency Motors & Spindles: Applications requiring minimal vibration at very high rotational speeds.
- Medical Equipment: Dental handpieces and other high-speed medical tools.
