S7014 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7014 CD/P4ADGA is a precision double row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, it excels in handling combined radial and axial loads simultaneously from both directions. Its compact double row design provides a high load capacity within a minimal cross-section, making it ideal for high-speed spindles and other high-precision, high-reliability machinery. The bearing comes pre-lubricated and sealed for long-term, maintenance-free operation.
S7014 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| CD | 15° Contact Angle, Universal Matchable (SU) Design | Optimized for high-speed operation and allows two bearings to be universally matched in any combination for precise preload control. |
| P4A | High Precision Tolerance Class | Exceeds ABEC-7 standards, ensuring extremely tight running accuracy for applications requiring minimal vibration and runout. |
| DGA | Sealed, Grease Lubricated | Features integral seals to retain lubricant and exclude contaminants, enabling a long service life with minimal maintenance. |
S7014 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact structure provides superior radial and axial stiffness, enabling stable support under combined loads. With a dynamic load rating of 18,720 lbf and static load rating of 20,588 lbf, it handles significant operational stresses.
- Optimized High-Speed Performance: The phenolic resin cage is lightweight and robust, contributing to a high limiting speed of 22,000 rpm. The 15° contact angle is ideal for high-speed applications where centrifugal forces are a primary concern.
- Precision & Longevity: Manufactured to P4A precision class with extremely tight dimensional tolerances on the bore, outside diameter, and width. The sealed and pre-greased design ensures consistent performance and protects against contamination across a wide temperature range (-30°C to 110°C).
S7014 CD/P4ADGA Bearing Typical Application Areas
This bearing is specified for high-performance applications where precision, speed, and reliability are critical. Key sectors include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Industrial Pumps & Compressors: For handling combined loads at high rotational speeds.
- High-Frequency Motors & Spindles: Used in robotics, CNC machinery, and other automated systems.
- Medical & Laboratory Equipment: Centrifuges and other precision instruments requiring quiet, vibration-free operation.
