S7004 CE/HCP4ADBG0 Bearing Product Overview & Core Advantages
The S7004 CE/HCP4ADBG0 is a precision angular contact ball bearing designed for demanding applications requiring exceptional performance. This metric system bearing features a duplex back-to-back (DB) matched arrangement, providing superior rigidity and the ability to handle combined loads (radial and axial) simultaneously. Manufactured to P4A super-precision tolerance and preloaded, it delivers outstanding running accuracy, making it ideal for high-speed machinery where reliability and precision are paramount.
S7004 CE/HCP4ADBG0 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7004 | Standard bearing series designation with 20mm bore, 42mm OD. |
| CE | Indicates a 15° contact angle. |
| HCP4A | Signifies P4A super-precision tolerance and specific internal design enhancements. |
| DB | Denotes a Duplex Back-to-Back preloaded matched set. |
| G0 | Specifies the preload level within the matched set. |
S7004 CE/HCP4ADBG0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement of two bearings creates a rigid support system that effectively resists moment loads and handles significant combined radial and axial loads.
- Superior High-Speed Performance: The combination of a lightweight phenolic resin cage, ceramic balls (Silicon Nitride), and pre-applied grease lubrication enables stable operation at the high limiting speed of 100,000 rpm. Ceramic balls reduce centrifugal forces, friction, and heat generation.
- Exceptional Precision & Longevity: Manufactured to P4A tolerance class for minimal runout and vibration. The sealed design protects against contamination, while the chrome steel rings and ceramic balls offer excellent wear resistance and a long operational life.
- Thermal Stability: The specified temperature range of -30°C to 110°C ensures consistent performance across various operating environments.
S7004 CE/HCP4ADBG0 Bearing Typical Application Areas
This high-precision, high-speed bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy positioning systems.
- High-Frequency Spindles: PCB drilling and routing equipment.
- Medical Equipment: Dental handpieces and laboratory centrifuges.
- Aerospace & Defense Systems: Gyroscopes, navigation instruments, and avionics.
