S7013 CE/P4ADBA Bearing Product Overview & Core Advantages
The S7013 CE/P4ADBA is a precision duplex angular contact ball bearing configured in a back-to-back (DB) arrangement. Engineered for the most demanding applications, this metric system bearing is characterized by its extra light preload (Class A) and P4A super-precision tolerance class. Its primary advantage lies in its ability to provide exceptionally high rigidity and stable rotational accuracy while accommodating combined radial and axial loads. The sealed design with phenolic cage makes it suitable for high-speed operation and long-term reliability in precision machinery.
S7013 CE/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S7013 | Basic bearing series and size designation | Defines the core dimensions: 65mm bore, 100mm OD, 36mm width. |
| CE | Contact angle of 15° | Optimized for handling axial loads in both directions. |
| P4A | Super Precision Tolerance Class | Guarantees extremely tight dimensional and running accuracy for high-precision applications. |
| DB | Duplex Back-to-Back Arrangement | Two bearings are mounted to provide high moment rigidity and stability. |
| (Sealed) | Integrated Seals | Protects against contamination and retains lubricant, enhancing service life. |
S7013 CE/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The duplex back-to-back (DB) arrangement of two matched bearings creates a wide effective spread, significantly increasing system rigidity and resistance to moment loads. This is critical for maintaining precision under heavy combined loads.
Superior Load Capacity: With a 15° contact angle and a dynamic load rating of 7470 lbf, this bearing is adept at managing significant radial and bidirectional axial loads simultaneously.
Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces and ensures stable operation at the high limiting speed of 36,000 rpm. The factory-applied grease lubrication is formulated for the specified temperature range (-30°C to 110°C).
Precision & Longevity: Manufactured to P4A tolerance class with chrome steel rings and balls, it guarantees minimal runout and smooth operation. The sealed design contributes to a maintenance-free and long service life by preventing lubricant loss and contaminant ingress.
