S7013 CE/P4ADGG5 Bearing Product Overview & Core Advantages
The S7013 CE/P4ADGG5 is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a universal matchable (SU) bearing, it can be paired with another identical bearing in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement without requiring selective shimming, simplifying installation and ensuring optimal preload. Its P4A tolerance class guarantees superior dimensional and running accuracy, making it ideal for high-speed spindles and other precision machinery. The bearing is pre-lubricated with grease and features a sealed design for long-term, maintenance-free operation.
S7013 CE/P4ADGG5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series, indicating a 65mm bore, 100mm OD, and 36mm width. |
| CE | Specific internal design featuring a 15° contact angle and optimized internal geometry. |
| P4A | High precision tolerance class exceeding ABEC 7, with enhanced running accuracy for spindle applications. |
| DG | "Universal Matchable" designation. The bearing is supplied as one of a universally matchable pair (SU). |
| G5 | Specifies the axial internal clearance group. |
S7013 CE/P4ADGG5 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 15° contact angle enables the bearing to support combined loads (radial and axial) simultaneously. The optimized raceway and ball complement provide high rigidity, essential for minimizing deflection in precision spindles.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the high-grade chrome steel balls and rings ensure dimensional stability at high rotational speeds, contributing to a high limiting speed of 36,000 rpm.
- Precision and Stability: Manufactured to P4A tolerance class, this bearing offers extremely tight dimensional control and low run-out, which is critical for achieving high rotational accuracy and reduced vibration in the final application.
- Sealed and Pre-Lubricated: The sealed design and factory-applied grease lubrication protect against contamination and provide a long service life without the need for re-lubrication, operating effectively within a temperature range of -30°C to 110°C.
S7013 CE/P4ADGG5 Bearing Typical Application Areas
This bearing is engineered for high-performance applications where precision, speed, and reliability are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Drives: High-frequency motors and servo drives.
- Aerospace & Defense: Gyroscopes, radar systems, and other precision instrumentation.
- Medical Equipment: High-speed dental handpieces and laboratory centrifuges.
