S7007 CE/P4ADBB Bearing Product Overview & Core Advantages
The S7007 CE/P4ADBB is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched set features a Back-to-Back (DB) arrangement and is manufactured to the stringent P4A tolerance class. Its core advantage lies in its ability to support combined loads (radial and axial) simultaneously while providing high running accuracy and stiffness, making it ideal for high-speed, high-precision spindles and machinery.
S7007 CE/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
- S7007: Basic series designation for a 35mm bore, 62mm OD angular contact ball bearing.
- CE: Indicates a universal match bearing designed for a specific contact angle (15°) and preload when mounted in a DB arrangement.
- P4A: Denotes a super-precision tolerance class exceeding ABEC 7, ensuring minimal runout and vibration for ultra-precise applications.
- DB: Specifies the Duplex Back-to-Back mounting arrangement. This configuration provides high rigidity against moment loads and increases operational stability.
- B: Indicates a Light preload is applied to the bearing set, minimizing deflection and optimizing performance under high-speed conditions.
S7007 CE/P4ADBB Bearing Structural Features & Performance Benefits
High Rigidity and Stability: The duplex Back-to-Back (DB) arrangement creates a wide, stable support system that effectively resists moment loads and shaft deflection, crucial for maintaining precision in machining operations.
Superior Load Capacity: With a 15° contact angle and a dynamic load rating of 4185 lbf, this bearing is engineered to handle significant combined radial and axial loads.
Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components and optimized internal geometry contribute to a high limiting speed of 56,000 rpm.
Sealed and Pre-Lubricated: The bearing is sealed and pre-lubricated with grease, offering protection from contaminants and providing reliable, maintenance-free operation within its specified temperature range of -30°C to 110°C.
S7007 CE/P4ADBB Bearing Typical Application Areas
This high-precision bearing set is ideally suited for demanding applications where accuracy, speed, and rigidity are paramount, including:
- Machine Tool Spindles (e.g., CNC milling, grinding, and turning centers)
- High-Frequency Spindle Motors
- Precision Robotics and Automation Equipment
- High-Speed Industrial Pumps and Compressors
