S7007 ACD/P4ADGC Bearing Product Overview & Core Advantages
The S7007 ACD/P4ADGC is a precision double row angular contact ball bearing designed for demanding industrial applications. Engineered to a P4A tolerance class, it delivers exceptional rotational accuracy and dimensional stability. Its primary advantage lies in its ability to simultaneously support substantial combined loads—both radial and bidirectional axial loads—thanks to its optimized 25° contact angle and double row design. This configuration offers a high rigidity solution in a compact envelope, making it ideal for high-speed spindles and other precision machinery requiring superior performance and reliability.

S7007 ACD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact structure provides significantly higher rigidity than single row bearings, effectively resisting complex combined loads and moments. With a dynamic load rating of 5445 lbf and static load rating of 4050 lbf, it is built for demanding operational conditions.
High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 41,000 rpm. The 25° contact angle provides an excellent balance between axial load capacity and speed capability.
Precision & Longevity: Manufactured to P4A tolerances from high-grade chrome steel for rings and balls, this bearing ensures minimal vibration and extended service life. It comes sealed and pre-lubricated with grease, offering protection against contamination and ready-for-installation convenience.
S7007 ACD/P4ADGC Bearing Typical Application Areas
The S7007 ACD/P4ADGC is ideally suited for high-performance machinery where precision, speed, and rigidity are paramount. Key application areas include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: High-accuracy measuring and testing equipment.
- High-Frequency Motors & Spindles: Applications requiring minimal runout at elevated speeds.
