S7013 ACDGC/P4A Bearing Product Overview & Core Advantages
The S7013 ACDGC/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This single-row bearing features a 25° contact angle and is supplied as a Universal Matchable (SU) bearing, allowing for precise preload control when mounted in pairs or sets. Its P4A tolerance class ensures ultra-precise dimensions and runout, making it ideal for high-speed spindles and other precision machinery where high rigidity and minimal deflection under combined loads are critical.
S7013 ACDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design, optimized for combined radial and axial loads. |
| DGC | Designates a specific internal geometry and Moderate preload (Class C) for high rigidity. |
| P4A | Indicates an ultra-precision tolerance class with even tighter controls on running accuracy than standard P4. |
S7013 ACDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and Moderate preload (Class C) provide superior system stiffness, minimizing axial and radial displacement under operational loads. The P4A tolerance class guarantees exceptional running accuracy for smooth, vibration-free operation.
- Optimized for Combined Loads: The angular contact design efficiently supports combined radial and axial loads simultaneously, a key requirement in precision applications.
- High-Speed Capability: The lightweight and robust phenolic cage ensures stability and reduced centrifugal forces, contributing to a high limiting speed of 31,000 rpm. The bearing is pre-lubricated with grease suitable for this performance envelope.
- Universal Matching: As a Universal Matchable (SU) bearing, the S7013 ACDGC/P4A can be mounted in duplex pairs (DB, DF, DT) to create a matched set with precisely controlled preload, further enhancing rigidity and rotational accuracy.
S7013 ACDGC/P4A Bearing Typical Application Areas
This precision bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, high-frequency motor spindles.
- Robotics: High-accuracy joints and actuators.
- Medical Equipment: Dental handpieces, imaging scanners.
- Aerospace Systems: Gyroscopes, navigation instruments.
