S7013 CE/HCP4ADBG28 Bearing Product Overview & Core Advantages
The S7013 CE/HCP4ADBG28 is a high-precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and rotational accuracy. This back-to-back (DB) matched set features a 15° contact angle and is preloaded, enabling it to handle significant combined loads (radial and axial) simultaneously from both directions. Manufactured to a P4A tolerance class, it delivers superior running accuracy and is optimized for high-speed operation up to 36,000 rpm, making it an ideal choice for high-performance spindles and precision machinery.
S7013 CE/HCP4ADBG28 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Bearing series and size designation (65mm bore, 100mm OD). |
| CE | Indicates a 15° contact angle. |
| HC | Hybrid Ceramic: Signifies ceramic balls for reduced weight, lower friction, and higher speed capability. |
| P4A | The tolerance class, denoting very high precision for both bore and outer diameter runouts. |
| DB | Duplex Back-to-Back: Specifies the matched arrangement of two bearings, providing high moment rigidity. |
| G28 | Likely refers to a specific preload level applied to the matched set. |
S7013 CE/HCP4ADBG28 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The back-to-back duplex arrangement creates a wide, stable support system that significantly increases moment stiffness. This design, combined with the 15° contact angle, allows the bearing set to effectively support heavy combined radial and axial loads from both directions.
- Superior High-Speed Performance: The use of lightweight ceramic balls reduces centrifugal forces, while the phenolic resin cage offers excellent strength-to-weight ratio and smooth operation at the limiting speed of 36,000 rpm.
- Enhanced Precision & Longevity: Manufactured to P4A tolerance class with tight dimensional control, this bearing ensures minimal runout and vibration. The sealed design and pre-applied grease lubrication protect against contamination and provide reliable operation within a temperature range of -30°C to 110°C.
- Preloaded for Immediate Performance: The bearings are supplied as a preloaded matched set, eliminating internal clearance and ensuring immediate, precise positioning and high system stiffness upon installation.
S7013 CE/HCP4ADBG28 Bearing Typical Application Areas
This bearing is engineered for the most demanding precision applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Robotics: High-accuracy robotic arm joints and rotary actuators.
- Aerospace & Defense Systems: Gyroscopes, radar platforms, and other critical navigation and targeting systems.
