S7011 CE/P4ADGB Bearing Product Overview & Core Advantages
The S7011 CE/P4ADGB is a high-precision double row angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to simultaneously handle combined radial and bidirectional axial loads, this bearing features a universal matchable (SU) design and a P4A super-precision tolerance class. Its compact double-row configuration provides high rigidity in a space-saving design, making it ideal for high-speed spindles and other precision machinery requiring reliable performance under complex loading conditions.
S7011 CE/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CE | Contact angle of 15° | Optimized for handling combined loads with balanced axial and radial capacity |
| P4A | Super precision tolerance class | Exceptional running accuracy for high-speed, high-precision applications |
| DGB | Universal matchable bearing (SU designation) | Can be mounted in any combination without preload adjustment requirements |
S7011 CE/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under heavy combined loads.
Enhanced Load Capacity: With a 15° contact angle and optimized internal geometry, this bearing efficiently handles both radial loads (6210 lbf dynamic rating) and bidirectional axial loads simultaneously.
High-Speed Performance: The phenolic resin cage ensures smooth operation at high speeds (46,000 rpm limiting speed) with reduced friction and excellent dimensional stability.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore tolerance: -0.004mm to 0), delivering exceptional running accuracy for demanding applications.
Universal Matching Capability: The SU designation allows flexible mounting arrangements without specific bearing pair selection, simplifying installation and maintenance.
