S7013 CE/HCP4A Bearing Product Overview & Core Advantages
The S7013 CE/HCP4A is a precision angular contact ball bearing engineered for high-performance applications requiring exceptional speed and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for applications demanding high running accuracy and minimal axial and radial deflection. Its construction with ceramic balls and a phenolic cage enables superior high-speed performance, reduced friction, and extended service life. The bearing is pre-lubricated and sealed for immediate use and long-term, maintenance-free operation in demanding environments.
S7013 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
| S7013 | Basic bearing series designation, indicating a high-precision angular contact design. |
| CE | Signifies the use of ceramic (hybrid) balls, which provide higher speed capability, reduced weight, and improved dielectric properties. |
| HCP4A | Indicates a P4 (ABEC-7) tolerance class for ultra-precise operation and a specific internal design (preload level 'A') optimized for high rigidity and minimal runout. |
S7013 CE/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed & Rigidity: The combination of a phenolic resin cage and ceramic balls significantly reduces centrifugal forces and friction, allowing for a high limiting speed of 22,000 rpm. The applied preload ensures high system stiffness, critical for precision machining and positioning.
- Superior Load Capacity: The 15° contact angle is optimized to handle combined radial and axial loads simultaneously. With a dynamic load rating of 4568 lbf and a static load rating of 3510 lbf, it offers reliable performance under significant stress.
- Precision & Longevity: Manufactured to P4 (ABEC-7) tolerance standards, this bearing guarantees exceptional running accuracy. The sealed design retains lubrication and excludes contaminants, ensuring consistent performance and a long, maintenance-free service life within a temperature range of -30° to 110°C.
