S7014 ACD/P4ADGB Bearing Product Overview & Core Advantages
The S7014 ACD/P4ADGB is a super-precision angular contact ball bearing designed for the most demanding high-speed and high-rigidity applications. Engineered to a P4A tolerance class, it delivers exceptional rotational accuracy and dimensional stability. Its core advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and thrust loads in both directions. The Universal Matchable (SU) designation allows for flexible mounting in preloaded sets, making it ideal for spindles requiring maximum stiffness and minimal runout.
S7014 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Basic bearing series and size designation (70mm Bore, 110mm OD, 40mm Width). |
| ACD | Contact Angle of 25° and a Light Preload (Class B) for optimal high-speed performance and rigidity. |
| P4A | Indicates an ultra-precision tolerance class exceeding ABEC 7/ISO P4, ensuring superior running accuracy. |
| DGB | Signifies a Universal Matchable (SU) bearing, supplied as one of a pair (2 bearings) that can be arranged in duplex sets (DB, DF, DT) without selective mounting. |
S7014 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and light preload are engineered to provide high axial and radial stiffness, enabling the bearing to handle significant combined loads with minimal deflection.
- Superior High-Speed Performance: The phenolic resin cage is lightweight and robust, reducing centrifugal forces and allowing for a high limiting speed of 22,000 rpm. This makes it an excellent high-speed bearing for spindle applications.
- Precision & Stability: Manufactured to P4A tolerances with tight dimensional control on the bore, outside diameter, and width, ensuring consistent performance and precise fit in high-accuracy assemblies.
- Sealed & Pre-Lubricated: As a sealed bearing with factory-applied grease lubrication, it is protected from contamination and is ready for immediate use, offering long-term, maintenance-free operation within its specified temperature range.
S7014 ACD/P4ADGB Bearing Typical Application Areas
This bearing is specifically designed for high-performance machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, precision grinding, and other applications requiring extreme accuracy.
- High-Frequency Motors: Spindles for routers and other high-RPM electric motors.
- Robotics: High-precision joints and arm assemblies.
