S71924 CD/P4ADGA Bearing Product Overview & Core Advantages
The S71924 CD/P4ADGA is a precision double-row angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to simultaneously handle combined radial and axial loads from both directions, its compact design offers a high-stiffness solution. Manufactured to the stringent P4A tolerance class and featuring a universal match (SU) designation, this bearing ensures superior running accuracy and is pre-configured for optimal performance in preloaded arrangements. Its sealed construction and pre-lubrication make it ideal for high-speed, long-life applications requiring minimal maintenance.
S71924 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number S71924 CD/P4ADGA provides detailed technical specifications:
- S7: Indicates a high-precision bearing series.
- 1924: Specifies the size series; 19 for the series and 24 for the bore diameter code (120 mm).
- C: Denotes a 15° contact angle, optimized for high-speed operation.
- D: Signifies a double-row design for increased rigidity and load capacity.
- P4A: The tolerance class, indicating ultra-precision dimensional and running accuracy.
- DG: Represents the preload level; in this case, Extra Light (Class A).
- A: Confirms the Universal Matchable (SU) arrangement, allowing for flexible mounting in pairs.
S71924 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact design provides superior stiffness, enabling stable support for shafts under combined loads. It can handle significant radial loads (28,125 lbf dynamic) and bidirectional axial loads efficiently.
- High-Speed Performance: The combination of a 15° contact angle and a lightweight, durable phenolic resin cage minimizes centrifugal forces and friction, allowing for a high limiting speed of 11,000 rpm.
- Precision & Longevity: Manufactured to P4A precision class with tight tolerances on all dimensions, this bearing ensures smooth, quiet, and accurate operation. The sealed construction and factory-applied grease lubrication protect against contamination and provide a long service life within a wide temperature range of -30°C to 110°C, making it a low-maintenance solution.
S71924 CD/P4ADGA Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery where accuracy, speed, and reliability are critical. Key applications include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Advanced Robotics and Automation Equipment
