S7014 ACDGC/P4A Bearing Product Overview & Core Advantages
The S7014 ACDGC/P4A is a precision angular contact ball bearing designed for high-performance applications. Engineered to the exacting P4A tolerance class, it delivers exceptional running accuracy and rotational stability. This bearing is uniquely capable of simultaneously supporting combined loads (radial and axial) and is supplied as part of a universally matchable set, allowing for flexible mounting configurations in preloaded arrangements. Its compact design, sealed construction, and optimized internal geometry make it an ideal choice for spindles and other mechanisms demanding high rigidity and reliability.
S7014 ACDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S7014 | Basic bearing series and size designation (70mm Bore, 110mm OD, 20mm Width). | Defines the core dimensions and series characteristics. |
| AC | Angular Contact design with a 25° contact angle. | Optimized for handling high axial loads in one direction. |
| DG | Universal matchable bearing designation. | Can be mounted in tandem, back-to-back, or face-to-face arrangements to achieve specific preload and stiffness. |
| C | Moderate preload / Class C. | Provides increased rigidity and minimizes axial and radial runout for enhanced precision. |
| P4A | High precision tolerance class. | Superior dimensional and running accuracy, suitable for high-speed, high-precision applications. |
S7014 ACDGC/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The angular contact design with a 25° contact angle and moderate preload (Class C) provides superior resistance to deflection under combined loads, ensuring maximum system stiffness and positioning accuracy.
Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the high-grade chrome steel components and precision manufacturing contribute to a high limiting speed of 22,000 rpm, making it a true high-speed bearing.
Sealed and Lubricated for Life: As a sealed bearing, it is protected from contamination and comes pre-lubricated with grease, offering a wide operating temperature range from -30°C to 110°C. This design provides long-term, maintenance-free operation in clean environments.
