S7003 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7003 CE/P4ADGA is a precision double row angular contact ball bearing designed for applications requiring exceptional accuracy and reliability. Engineered with P4A tolerance class and extra light preload (Class A), this bearing delivers superior rotational precision and minimal running torque. Its double row design provides high rigidity and enables it to support combined loads (radial and bidirectional axial loads) simultaneously, making it ideal for compact, high-performance arrangements. The sealed construction with phenolic cage ensures reliable operation in demanding conditions.
S7003 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Contact angle of 15° | Optimized for axial load capacity |
| P4A | High precision tolerance class | Superior running accuracy and minimal vibration |
| DGA | Universal Matchable (SU) arrangement | Flexible mounting options and simplified installation |
S7003 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design with 15° contact angle provides exceptional stiffness and enables the bearing to handle significant combined radial and axial loads from both directions. With a dynamic load rating of 2151 lbf and static load rating of 1148 lbf, it offers reliable performance under demanding operating conditions.
Precision Performance: Manufactured to P4A tolerance class with extra light preload, this bearing ensures minimal runout and vibration, making it suitable for high-speed applications up to 85,000 rpm. The phenolic cage contributes to smooth operation at high speeds while reducing weight and friction.
Maintenance-Free Operation: The sealed construction with factory-applied grease lubrication provides long-term, maintenance-free service within the temperature range of -30°C to 110°C. The universal matchable design allows for flexible bearing arrangements without additional adjustments.
