S7012 CD/P4ADBA Bearing Product Overview & Core Advantages
The S7012 CD/P4ADBA is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. This duplex back-to-back (DB) matched set delivers superior performance by providing high rigidity and the ability to withstand combined loads (radial and axial). Manufactured to P4A tolerance class, it ensures minimal runout and smooth operation, making it ideal for high-speed spindles and precision machinery. The phenolic cage and pre-lubrication with grease contribute to its high-speed capability and long service life.
S7012 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7012 CD/P4ADBA is decoded as follows:
- S7012: Basic bearing designation (60mm bore, 95mm OD, 36mm width)
- C: 15° contact angle
- D: Duplex arrangement
- P4A: High precision tolerance class (exceeds ABEC 7)
- DB: Specific duplex configuration (Back-to-Back)
- A: Light preload
S7012 CD/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively counteracts moment loads and prevents shaft misalignment, which is critical for machining accuracy.
- Superior Load Capacity: With a 15° contact angle and a dynamic load rating of 14,918 lbf, this bearing is engineered to handle significant combined radial and axial loads simultaneously.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry and grease lubrication enable a high limiting speed of 31,000 rpm.
- Precision & Accuracy: Manufactured to a P4A tolerance class with tight dimensional controls on bore, outside diameter, and width, this bearing ensures minimal vibration and exceptional running accuracy.
S7012 CD/P4ADBA Bearing Typical Application Areas
This high-precision duplex bearing is ideally suited for applications where rigidity, speed, and accuracy are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes and High-Frequency Motors.
- Medical Equipment: Dental handpieces and imaging device rotors.
- Aerospace & Defense Systems: Gyroscopes, radar equipment, and auxiliary power units.
