S7011 CE/P4ADBG5 Bearing Product Overview & Core Advantages
The S7011 CE/P4ADBG5 is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. This matched set in a back-to-back (DB) arrangement is pre-configured to provide superior stiffness and stability, enabling it to handle combined loads (radial and bidirectional axial loads) simultaneously. Manufactured to a P4A tolerance class, it guarantees high running accuracy and is pre-lubricated for immediate use, making it an ideal solution for high-speed, high-precision machinery where reliability is paramount.
S7011 CE/P4ADBG5 Bearing Model Code Explained, Specifications & Naming Convention
The model designation S7011 CE/P4ADBG5 provides detailed technical specifications:
- S7011: Denotes the bearing series and size (55mm bore, 90mm OD, 36mm width).
- C: Indicates a 15° contact angle, optimized for high-speed operation and moderate axial load capacity.
- E: Signifies a high-capacity internal design with optimized ball size and quantity.
- P4A: The tolerance class, specifying extremely tight dimensional and running accuracy standards.
- DB: Specifies a duplex back-to-back mounting arrangement, which increases moment rigidity.
- G5: Indicates a specific preload level applied to the matched set for optimal operational performance.
S7011 CE/P4ADBG5 Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) design creates a wide effective spread, significantly increasing the bearing's resistance to moment loads and providing exceptional system stiffness.
- Superior Load Capacity: The angular contact design and high-capacity (E) internal geometry enable the bearing to support substantial combined radial and axial loads from both directions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the 15° contact angle and precision grinding contribute to a high limiting speed of 46,000 rpm.
- Precision & Longevity: Manufactured to P4A tolerance class from chrome steel, the bearing ensures minimal runout and vibration. It is sealed and pre-lubricated with grease, protecting against contamination and providing long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S7011 CE/P4ADBG5 Bearing Typical Application Areas
This bearing is ideally suited for high-precision, high-speed applications, including:
- Machine Tool Spindles (e.g., for milling, grinding, and turning centers)
- High-Frequency Spindles
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotic Arms and Precision Positioning Systems
