SV7014 FE/P4ADGA Bearing Product Overview & Core Advantages
The SV7014 FE/P4ADGA is a precision double-row angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to simultaneously withstand radial loads and bidirectional axial loads, this bearing features a compact design ideal for space-constrained, high-reliability machinery. Its P4A tolerance class ensures superior running accuracy, while the phenolic cage and sealed construction contribute to outstanding high-speed performance and long-term, maintenance-free operation.
SV7014 FE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number SV7014 FE/P4ADGA provides detailed technical specifications:
- SV7014: Basic bearing designation, indicating a double-row angular contact ball bearing with a 70mm bore.
- FE: Indicates the bearing is sealed on both sides, providing superior protection against contamination.
- P4A: Denotes an extremely high tolerance class, signifying very tight dimensional and running accuracy for precision applications.
- DGA: Specifies the bearing is part of a Universal Matchable (SU) set, allowing two bearings to be mounted in any combination (face-to-face, back-to-back, or tandem) to achieve the desired preload and rigidity.
SV7014 FE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row design and 18° contact angle provide significantly higher radial and axial rigidity compared to single-row bearings, enabling stable support under combined loads.
- Precision & High-Speed Performance: The P4A precision grade ensures minimal runout and vibration. Combined with the lightweight phenolic resin cage, this allows for a high limiting speed of 28,000 rpm.
- Sealed & Lubricated for Life: The integral seals (FE) effectively retain the factory-applied grease lubrication and exclude contaminants, making the bearing maintenance-free and suitable for a wide operating temperature range of -30°C to 110°C.
- Universal Matching: As a Universal Matchable (SU) bearing, it offers exceptional flexibility in spindle design, allowing for precise control of preload and system stiffness when used in pairs.
SV7014 FE/P4ADGA 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 Spindles: PCB drilling, high-frequency motors, and dental handpieces.
- Industrial Pumps & Compressors: Applications requiring robust performance under combined loads.
- Robotics: Joint and arm articulation requiring high rigidity and accuracy.
