S7006 ACEGA/P4A Bearing Product Overview & Core Advantages
The S7006 ACEGA/P4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Positioned in the P4A super-precision tolerance class, it delivers exceptional rotational accuracy and dimensional stability. Its defining capability is efficiently supporting combined loads (simultaneous radial and axial loads) in one direction, a result of its optimized 25° contact angle. The bearing features a sealed design with pre-lubrication, offering a maintenance-free solution with a wide operating temperature range, making it ideal for demanding, high-reliability systems.
S7006 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| AC | Angular Contact | Designed to support combined radial and axial loads. |
| EGA | Contact Angle & Preload | Indicates a 25° contact angle and Extra Light (Class A) preload for high rigidity and precise running. |
| P4A | Tolerance Class | Denotes super-precision tolerances for bore, outside diameter, and width, ensuring exceptional accuracy. |
S7006 ACEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact angle and Extra Light preload (Class A) provides superior system stiffness and minimizes axial and radial runout, which is critical for high-precision spindles.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the high-grade chrome steel balls and rings contribute to a high limiting speed of 100,500 rpm.
- Robust Load Capacity: With a dynamic load rating of 1989 lbf and a static load rating of 1125 lbf, this bearing is built to handle significant combined loads over a long service life.
- Sealed and Maintenance-Free: The sealed design with factory-applied grease lubrication protects against contamination and provides reliable operation within a temperature range of -30°C to 110°C without requiring re-lubrication.
- Universal Matching (SU): This bearing is universally matchable, allowing for flexible arrangement in sets (back-to-back, face-to-face, or tandem) to meet specific application requirements for rigidity and load capacity.
S7006 ACEGA/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance machinery requiring speed, accuracy, and reliability.
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: High-accuracy joints and arm assemblies.
- High-Frequency Motors and Spindles: PCB drilling spindles and dental handpieces.
- Aerospace and Defense Systems: Gyroscopes, radar equipment, and navigation instruments.
