S7013 FE/P4ADBA Bearing Product Overview & Core Advantages
The S7013 FE/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This back-to-back (DB) matched pair configuration provides superior stability and can accommodate combined radial and axial loads from both directions. Manufactured to the stringent P4A tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed, high-precision machinery where reliability is paramount.
S7013 FE/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| S | Super-precision | Indicates a bearing designed for ultra-high precision applications. |
| 7013 | Standard Size Designation | Defines the core dimensions: 65mm bore, 100mm OD, 36mm width. |
| FE | Sealed | Integrated seals protect against contamination and retain lubricant. |
| P4A | Tolerance Class | Denotes extremely tight dimensional and running accuracy, superior to ABEC 7. |
| DB | Duplex Back-to-Back | Two bearings are matched and mounted back-to-back to withstand moment loads and provide high rigidity. |
| A | Preload (Extra Light) | Specifies a minimal preload for optimal high-speed performance with reduced friction and heat generation. |
S7013 FE/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back arrangement creates a rigid bearing system capable of withstanding significant combined radial and axial loads and moment loads. The 18° contact angle is optimized for a balance of axial and radial load carrying capacity.
Superior High-Speed Performance: The lightweight, durable phenolic resin cage minimizes centrifugal forces and ensures stable operation at the high limiting speed of 31,000 rpm. The extra light preload (A) further enhances high-speed capability by minimizing friction.
Sealed & Pre-Lubricated for Longevity: The integral seals (FE) effectively shield the precision-ground chrome steel components from contaminants. The bearing is pre-lubricated with grease, offering a wide operating temperature range from -30°C to 110°C and providing a long, maintenance-free service life in many applications.
