| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| CE | 15° Contact Angle | Optimized for high-speed operation and axial load capacity |
| P4A | High Precision Tolerance Class | Provides exceptional dimensional and running accuracy for precision applications |
| DT | Duplex Tandem Arrangement | Enables handling of heavy axial loads in one direction through bearing pairing |
7004 CE/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem configuration and 15° contact angle create a highly rigid bearing system capable of withstanding substantial axial loads in one direction while maintaining excellent radial load capacity. This makes it suitable for applications with demanding combined load requirements.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional tolerances on bore, outside diameter, and width, ensuring minimal runout and vibration for superior rotational accuracy.
High-Speed Capability: The phenolic cage material and optimized internal design contribute to the bearing's ability to operate at limiting speeds up to 121,000 rpm, making it an excellent choice for high-speed applications.
Enhanced Durability: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and fatigue life. The bearing comes pre-lubricated for immediate operation within its specified temperature range of -30°C to 110°C.
