S7011 CD/P4ADGB Bearing Product Overview & Core Advantages
The S7011 CD/P4ADGB is a precision angular contact ball bearing engineered for applications demanding exceptional accuracy and reliability. Operating under the stringent P4A tolerance class, this bearing is designed to simultaneously handle combined radial and axial loads. Its universal matchable (SU) design allows for flexible mounting arrangements, while the light preload (Class B) ensures optimal rigidity and minimal runout. The combination of a phenolic cage and high-grade grease lubrication makes it an ideal solution for high-speed operation and long service life in demanding environments.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| CD | 15° contact angle, universal matchable design | Optimized for combined loads, allows flexible mounting in pairs |
| P4A | High precision tolerance class | Superior running accuracy for precision applications |
| DGB | Sealed construction with grease filling | Contamination protection and maintenance-free operation |
S7011 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The bearing's optimized internal geometry and 15° contact angle provide excellent resistance to both radial and axial forces, with dynamic and static load ratings of 14,332 lbf and 14,738 lbf respectively. The universal matchable design enables paired mounting for enhanced stiffness in applications requiring high rigidity.
High-Speed Performance: The phenolic cage ensures stable operation at limiting speeds up to 46,000 rpm, while the precision-ground chrome steel components minimize friction and heat generation. The optimized ball quantity (18) and ball diameter (11.112 mm) contribute to smooth rotation and reduced vibration.
Maintenance-Free Operation: With integrated seals and factory-applied grease, the bearing offers reliable performance across a wide temperature range (-30°C to 110°C) without requiring relubrication. This sealed construction protects against contamination while ensuring consistent performance throughout the bearing's service life.
