Product Overview and Core Advantages
The 7013 FE/HCP4AH1DT is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This duplex tandem (DT) arrangement bearing set offers superior axial rigidity and is preloaded for optimal performance under high-speed conditions. Manufactured to an ultra-precise P4A tolerance class, it ensures minimal runout and vibration. Its construction with ceramic balls and a phenolic cage enables superior high-speed performance and reduced rotational inertia, making it ideal for machine tool spindles and other precision machinery.
7013 FE/HCP4AH1DT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing series and size designation (65mm bore, 100mm OD). |
| FE | Indicates a specific internal design and contact angle (18°) optimized for high-speed operation. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride). |
| P4A | The tolerance class, denoting ultra-high precision for bore, outer diameter, and width. |
| H | Indicates a specific preload level applied to the bearing set. |
| 1 | Specifies the preload group or level within the "H" category. |
| DT | Denotes a Duplex Tandem arrangement, where two bearings are mounted together to maximize axial load capacity in one direction. |
Structural Features and Performance Benefits
High-Speed and High-Rigidity Design: The combination of a phenolic resin cage and lightweight ceramic balls significantly reduces centrifugal forces, allowing for a limiting speed of 32,500 rpm. The duplex tandem arrangement and built-in preload provide exceptional axial and radial rigidity, minimizing deflection under load.
Superior Load Capacity: The 18° contact angle and tandem configuration are engineered to handle heavy axial loads in one direction. With a dynamic load rating of 7312 lbf, this bearing set offers reliable performance under demanding conditions.
Ultra-Precision Operation: Manufactured to P4A tolerance class, this bearing ensures extremely tight dimensional control, resulting in smooth, quiet, and vibration-free operation, which is critical for high-precision applications.
Optimized for Performance: The open seal type allows for custom lubrication schemes to be implemented for specific operational environments, maximizing performance and service life.
