S7003 CDGA/P4A Bearing Product Overview & Core Advantages
The S7003 CDGA/P4A is a super-precision double row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This universally matchable bearing features a Class A extra light preload and a P4A tolerance class, making it ideal for high-speed spindles and other precision machinery. Its double row design enables it to support combined radial and axial loads from both directions simultaneously, offering a compact and highly reliable solution for critical applications.
S7003 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7003 | Super-precision double row angular contact ball bearing series with 17mm bore, 35mm OD. |
| CDGA | Specific internal design and clearance/preload designation for universal matching (SU). |
| P4A | Indicates a super-precision tolerance class with enhanced running accuracy. |
S7003 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and 15° contact angle provide high rigidity and enable the bearing to handle significant combined loads.
- Super-Precision Performance: Manufactured to P4A tolerance class with extremely tight dimensional tolerances on the bore, outside diameter, and width for superior running accuracy.
- High-Speed Capability: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 85,000 rpm.
- Universal Matchability: As a Universal Matchable (SU) bearing, two identical S7003 CDGA/P4A bearings can be mounted together in a universal arrangement to achieve precise preload and system rigidity.
- Sealed & Lubricated for Life: The sealed design with factory-applied grease protects against contamination and provides maintenance-free operation within the specified temperature range.
