S7009 CEGA/P4A Bearing Product Overview & Core Advantages
The S7009 CEGA/P4A is a super-precision angular contact ball bearing designed for the most demanding high-speed and high-rigidity applications. Manufactured to the stringent P4A tolerance class, it delivers exceptional running accuracy and dimensional stability. Its 15° contact angle and universal matchable (SU) design allow for flexible mounting in preloaded duplex arrangements, enabling it to support combined radial and axial loads simultaneously. This bearing is the ideal solution for machine tool spindles and other precision equipment requiring superior performance.
S7009 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7009 CEGA/P4A provides detailed technical specifications:
- S70: Indicates a super-precision angular contact ball bearing series.
- 09: Denotes the bore diameter code (45 mm).
- C: Signifies a 15° contact angle.
- E: Designates a high-capacity phenolic resin cage.
- GA: Indicates a universal matchable (SU) bearing for duplex mounting.
- P4A: Specifies the tolerance class, which is even more precise than standard ABEC 7 (P4) and includes specific running accuracy requirements.
S7009 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized internal geometry, combined with the phenolic resin cage and 21 high-grade chrome steel balls, provides excellent structural integrity to handle significant combined loads.
- Superior High-Speed Performance: The lightweight and robust phenolic cage, along with the precision-ground components, allows for a high limiting speed of 41,000 rpm, making it a true high-speed bearing.
- Exceptional Precision: Manufactured to P4A tolerance class with tight bore, outside diameter, and width tolerances, this bearing ensures minimal runout and vibration for superior application performance.
- Pre-Lubricated & Sealed: The bearing comes pre-lubricated with grease and is sealed, protecting it from contamination and providing long-term, maintenance-free operation within its specified temperature range.
S7009 CEGA/P4A Bearing Typical Application Areas
The S7009 CEGA/P4A is engineered for high-performance applications, including:
- Machine Tool Spindles (High-speed milling, grinding, and turning centers)
- Precision Grinding Spindles
- High-Frequency Motors
- Aerospace & Defense Systems
- Medical & Dental Equipment Spindles
