S7013 ACDGA/P4A Bearing Product Overview & Core Advantages
The S7013 ACDGA/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 a 25° contact angle and Extra Light (Class A) preload, it is engineered to handle combined loads—significant radial loads and axial loads in one direction. Its P4A tolerance class ensures ultra-precision operation, making it ideal for high-rigidity spindles and other critical machinery where minimal runout and high reliability are paramount.
S7013 ACDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| AC | Angular Contact | Optimized for combined radial and axial loads. |
| DGA | Universal Matchable (SU designation) | Can be universally matched in sets (up to 4 bearings) for preload control and increased stiffness. |
| P4A | Super Precision Tolerance Class | Exceeds ABEC-7 standards, ensuring extremely tight running accuracy for high-speed, high-precision applications. |
S7013 ACDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and Extra Light preload provide excellent rigidity, enabling the bearing to support substantial combined loads with high stability.
- 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.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on the 65 mm bore and 100 mm outside diameter, ensuring minimal vibration and precise shaft positioning.
- Sealed & Pre-Lubricated: The sealed design with factory-applied grease protects against contamination and provides reliable operation within a temperature range of -30°C to 110°C, reducing maintenance needs.
S7013 ACDGA/P4A Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery, including:
- Machine Tool Spindles (e.g., CNC milling, grinding, and turning centers)
- High-Speed Motors and Precision Gearboxes
- Industrial Pumps and Compressors
- Aerospace & Defense Actuation Systems
- Medical & Laboratory Equipment requiring high rotational accuracy
