7011 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7011 CD/P4ADGA is a precision angular contact ball bearing manufactured to P4A tolerance class for exceptional dimensional and running accuracy. Designed with a 15° contact angle and Universal Matchable (SU) designation, it is engineered to handle combined loads—significant radial loads and axial loads in one direction. Its extra light preload (Class A) ensures minimal friction and high rotational accuracy, making it an ideal solution for high-speed, high-precision applications requiring superior rigidity and performance.
7011 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a universal matchable bearing designed for duplex mounting (DB, DF, DT). |
| P4A | Specifies a high-precision tolerance class with enhanced running accuracy requirements. |
| DGA | Denotes extra light preload (Class A) for optimal stiffness and low operating torque. |
7011 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: Manufactured to P4A tolerance standards with a phenolic cage, this bearing delivers exceptional dimensional stability and running accuracy, essential for high-precision spindles.
- Superior Load Capacity: The 15° contact angle and optimized internal geometry enable efficient handling of combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic cage and open design contribute to a high limiting speed of 34,000 rpm, reducing centrifugal forces and heat generation.
- Universal Matching Capability: As a Universal Matchable (SU) bearing, it can be paired in various duplex arrangements (DB, DF, DT) to achieve specific stiffness and load-sharing characteristics without selective mounting.
7011 CD/P4ADGA Bearing Typical Application Areas
This precision bearing is ideally suited for demanding applications where high speed, high rigidity, and exceptional accuracy are critical. Key industries and equipment include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps & Compressors
- Aerospace & Defense Actuation Systems
