S7013 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7013 CE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As part of the universal matchable (SU) series, it can be mounted in tandem, face-to-face, or back-to-back arrangements to optimize system rigidity. Its key advantages include the ability to handle combined loads (simultaneous radial and axial loads), superior running accuracy from its P4A tolerance class, and high-speed capability enabled by its phenolic cage and optimized internal geometry.
S7013 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series and size designation (65mm bore, 100mm OD, 36mm width) |
| CE | High-capacity, optimized internal geometry with a 15° contact angle |
| P4A | High-precision tolerance class with enhanced dimensional and running accuracy |
| DGA | Indicates a universal matchable (SU) bearing set, consisting of two bearings (preload: Extra light / Class A) |
S7013 CE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized internal design and 15° contact angle enable superior support for combined radial and axial loads, making it ideal for applications requiring high system stiffness.
- High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 36,000 rpm. The grease lubrication is formulated for stable operation at these elevated speeds.
- Precision Engineering: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for the accuracy of precision machinery.
- Sealed & Pre-Lubricated: The bearing is sealed and pre-filled with grease, offering protection against contamination and providing long-term, maintenance-free operation within its specified temperature range of -30°C to 110°C.
S7013 CE/P4ADGA Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers, grinding spindles.
- High-Speed Motors & Spindles: Electric motors, CNC router spindles.
- Precision Instrumentation: Measuring devices, optical scanners.
- Robotics: High-accuracy joints and rotary axes.
