S71914 CDGA/P4A Bearing Product Overview & Core Advantages
The S71914 CDGA/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a single-row bearing with a 15° contact angle, it excels at handling combined loads, accommodating high radial forces alongside significant axial loads in one direction. Manufactured to P4A tolerance class, it delivers superior running accuracy and rotational precision. Its sealed design and pre-lubrication with grease ensure long-term performance and minimal maintenance, making it ideal for high-speed spindles and precision machinery.
S71914 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S | Designates a universal match bearing designed for preload adjustment when mounted with other bearings. |
| 71914 | Basic bearing designation indicating a metric, single-row angular contact ball bearing with a 70mm bore, 100mm OD, and 16mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| DG | Indicates a Universal Matchable (SU) bearing, supplied as part of a set of three bearings (A, DB, or DF arrangements possible) for precise preload control. |
| A | Denotes Extra Light Preload (Class A), minimizing friction and heat generation for superior high-speed performance. |
| P4A | Specifies a high-precision tolerance class with extremely tight dimensional and running accuracy limits for critical applications. |
S71914 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P4A tolerance class with exceptionally tight bore, OD, and width tolerances, this bearing provides superior running accuracy, minimal vibration, and high system rigidity for precise positioning applications.
- Optimized Load Capacity: The 15° contact angle and high-grade chrome steel construction enable efficient handling of combined radial and axial loads, with a dynamic load rating of 7762 lbf and static load rating of 7650 lbf.
- Superior High-Speed Performance: The combination of a lightweight, high-strength phenolic cage, extra light preload (Class A), and optimized internal geometry allows for a high limiting speed of 28,000 rpm.
- Sealed & Lubricated for Life: The integral seals protect against contamination, while the factory-applied grease lubrication operates effectively within a temperature range of -30°C to 110°C, offering long service life with minimal maintenance.
S71914 CDGA/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning spindles requiring extreme precision and rigidity.
- Precision Instrumentation: Measuring devices, optical scanners, and coordinate measuring machines (CMM).
- High-Speed Motors & Drives: Spindles for PCB drilling, dental handpieces, and small precision motors.
- Robotics: Joints and actuators in industrial robots where accuracy and high-speed operation are critical.
