S7013 CE/HCP4BVG275 Bearing Product Overview & Core Advantages
The S7013 CE/HCP4BVG275 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a single-row design with a 15° contact angle, optimized for high rigidity and precise operation. Its construction with ceramic balls and a phenolic cage enables superior high-speed performance and reduced rotational inertia. Pre-lubricated and sealed, it offers reliable, long-term service in precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series designation, indicating a metric, single-row angular contact ball bearing with specific dimensions (65mm bore, 100mm OD, 18mm width). |
| CE | Indicates the use of ceramic balls (typically Silicon Nitride, Si3N4), which reduce weight, friction, and heat generation, enhancing high-speed capability. |
| HC | Refers to the phenolic resin cage material, offering high strength, low weight, and excellent performance at high rotational speeds. |
| P4 | Specifies the tolerance class P4 (ABEC-7), denoting very high precision in dimensions and running accuracy. |
| BVG275 | Likely denotes a specific internal design, preload level, and/or lubrication specification for optimized performance. |
S7013 CE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The P4 (ABEC-7) tolerance class ensures minimal runout and vibration, providing stable and accurate rotational performance essential for precision applications.
- Superior High-Speed Capability: The combination of ceramic balls and a lightweight phenolic cage significantly reduces centrifugal forces, allowing for a high limiting speed of 22,000 rpm.
- Excellent Load Capacity: The 15° contact angle is optimized to handle significant combined radial and axial loads (Dynamic: 4568 lbf, Static: 3510 lbf).
- Pre-Lubricated and Sealed: Comes factory-filled with grease and sealed, making it ready for immediate use and providing protection against contamination, resulting in a maintenance-free design within its specified temperature range.
- Preload Availability: The availability of preload allows for precise control over bearing stiffness and rotational accuracy, eliminating internal clearance for enhanced system rigidity.
S7013 CE/HCP4BVG275 Bearing Typical Application Areas
This high-performance precision bearing is ideally suited for:
- Machine Tool Spindles: High-speed machining centers, grinding spindles, and CNC lathes.
- High-Speed Motors and Spindles: Electric motors, turbochargers, and dental handpieces.
- Precision Instrumentation: Optical scanners, measuring devices, and semiconductor manufacturing equipment.
- Aerospace and Defense Systems: Gyroscopes, radar systems, and auxiliary power units (APUs).
