S7013 ACD/HCP4ADGA Bearing Product Overview & Core Advantages
The S7013 ACD/HCP4ADGA is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a double-row design with a 25° contact angle, enabling it to handle combined radial and axial loads simultaneously from both directions. Manufactured to P4A super-precision tolerance and utilizing ceramic balls and a phenolic cage, it delivers superior high-speed capability, high rigidity, and extended service life in critical machinery.
S7013 ACD/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACD | 25° Contact Angle, Double Row Design | Optimized for high axial load capacity and rigidity. |
| HC | Hybrid Ceramic (Silicon Nitride Balls) | Reduced friction, lower operating temperature, and extended high-speed performance. |
| P4A | Super Precision Tolerance Class | Ensures extreme running accuracy and minimal vibration for precision applications. |
| DGA | Grease Lubrication, Sealed on Both Sides | Provides contamination protection and is lubricated for life, reducing maintenance needs. |
S7013 ACD/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact design and 25° contact angle provide exceptional stiffness, enabling the bearing to support significant combined loads (radial and bidirectional axial loads) with minimal deflection.
- Superior High-Speed Performance: The combination of lightweight phenolic resin cage and low-density ceramic balls reduces centrifugal forces, allowing for a high limiting speed of 32,500 rpm. This makes it ideal for high-speed spindles.
- Precision & Longevity: Manufactured to P4A tolerance class with a narrow bore and outside diameter tolerance of -0.004mm to 0, ensuring precise shaft alignment and smooth operation. The hybrid ceramic construction offers increased durability and resistance to wear.
- Maintenance-Free Operation: The integral seals and pre-applied grease lubrication protect against contaminants and provide reliable operation within a temperature range of -30°C to 110°C, making it a long-life, sealed bearing solution.
S7013 ACD/HCP4ADGA Bearing Typical Application Areas
This high-performance bearing is engineered for use in precision equipment where speed, accuracy, and reliability are paramount. Key applications include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Medical Equipment: Dental handpieces, centrifuges, and imaging devices.
- Aerospace & Defense: Gyroscopes, radar systems, and auxiliary power units (APUs).
- High-Frequency Motors and Pumps: Where low friction and high rotational accuracy are required.
