S7011 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7011 CE/P4ADGA is a precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. This P4A tolerance class bearing is designed to simultaneously handle significant combined loads (radial and bidirectional axial loads), making it ideal for high-speed, high-precision spindles and machinery. Its compact design, featuring a universal match (SU) configuration, ensures easy installation and optimal performance in space-constrained environments requiring superior running accuracy.
S7011 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Contact angle of 15° and polyamide (phenolic) cage. |
| P4A | High precision tolerance class, exceeding ABEC 7 standards, with restricted runout tolerances. |
| DGA | Universal Matchable (SU) bearing pair with extra light preload (Class A). |
S7011 CE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior radial and axial stiffness, enabling stable operation under combined loads. With a dynamic load rating of 6210 lbf and static load rating of 5512 lbf, it offers robust performance.
- High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 46,000 rpm. The optimized 15° contact angle further enhances speed capability.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight bore and OD tolerances, this bearing ensures minimal runout and vibration for critical high-speed applications.
- Sealed & Lubricated for Life: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is maintenance-free within its specified temperature range of -30°C to 110°C.
S7011 CE/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications including:
- Machine Tool Spindles (CNC machining centers, grinding spindles)
- High-Speed Motors and Precision Spindles
- Industrial Pumps and Compressors
- Robotic Drives and Precision Instrumentation
