7012 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7012 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, it offers superior running precision. Its key advantage lies in its Universal Matchable (SU) design, allowing two bearings to be universally paired for optimal preload and performance in a back-to-back (DB) or face-to-face (DF) arrangement. This makes it ideal for supporting combined loads (radial and axial) simultaneously in high-speed, high-rigidity applications such as machine tool spindles.
7012 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7012 | Basic bearing series and size designation (60mm bore, 95mm OD). |
| C | 15° contact angle. |
| D | Light preload / Class B preload. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards. |
| DB | Two bearings supplied as a Universal Matchable (SU) set in a back-to-back arrangement. |
7012 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and Universal Matchable (SU) pairing enable the bearing set to handle significant combined radial and axial loads. The specified light preload (Class B) eliminates internal clearance, resulting in high system stiffness, which is critical for precision machining and positioning.
- High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, reducing friction and heat generation. This, combined with the optimized 15° contact angle, allows for a high limiting speed of 34,000 rpm, making it suitable for high-speed spindles.
- Precision & Accuracy: Manufactured to a P4A tolerance class with tight dimensional runout tolerances, this bearing ensures exceptional running accuracy, reduced vibration, and consistent performance in demanding applications.
- Material & Lubrication: Constructed from chrome steel for both rings and balls, providing high durability and fatigue resistance. The bearing is pre-lubricated for immediate operation within a temperature range of -30°C to 110°C.
7012 CD/P4ADGB Bearing Typical Application Areas
This precision angular contact ball bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: High-accuracy joints and arm assemblies.
- High-Frequency Motors & Spindles
- Medical Equipment: Dental handpieces and imaging devices.
- Aerospace & Defense Systems: Gyroscopes and navigation instruments.
