S7013 CDGA/P4A Bearing Product Overview & Core Advantages
The S7013 CDGA/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. Engineered with an Extra Light (Class A) preload and manufactured to P4A tolerance class, this bearing delivers superior rotational accuracy and rigidity. Its 15° contact angle is optimized to handle combined loads—significant radial loads alongside axial loads in one direction—making it an ideal, compact solution for high-precision spindles and other critical machinery where reliability and precision are paramount.
S7013 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CDGA | Indicates a Universal Matchable (SU) bearing designed for duplex mounting. This specific code defines the contact angle and preload (15°, Extra Light/Class A) to ensure precise performance when mounted in pairs (back-to-back, face-to-face, or tandem). |
| P4A | Denotes an ultra-high precision tolerance class that exceeds ABEC 7 standards. This ensures minimal runout and vibration for superior performance in high-speed, high-accuracy applications. |
S7013 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and phenolic cage provide excellent stability, enabling the bearing to support substantial combined loads with high system rigidity.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry and grease lubrication contribute to a high limiting speed of 36,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance with tight dimensional controls on the bore diameter (65 mm), outside diameter (100 mm), and width (18 mm), ensuring consistent and reliable performance in precision assemblies.
- Sealed & Pre-Lubricated: As a sealed bearing pre-filled with grease, it is protected from contamination and is ready for immediate use, offering long-term, maintenance-free operation within its specified temperature range (-30°C to 110°C).
S7013 CDGA/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- High-Speed Pumps and Compressors
- Aerospace & Defense Instrumentation
