S71913 CE/P4ADGA Bearing Product Overview & Core Advantages
The S71913 CE/P4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable bearing with a 15° contact angle and P4A tolerance class, it delivers superior performance in handling combined radial and axial loads. Its sealed design and pre-lubrication ensure long-term reliability and minimal maintenance, making it ideal for high-speed spindles and precision machinery where operational consistency is critical.
S71913 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a universal matchable (SU) bearing designed to be mounted in any combination (face-to-face, back-to-back, or tandem) without preload adjustment. |
| P4A | Specifies an extra light preload (Class A) and high-precision P4 tolerance class, ensuring minimal runout and superior rotational accuracy. |
| DGA | Denotes the bearing is sealed and pre-lubricated with grease, providing contamination protection and ready-to-install convenience. |
S71913 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 15° contact angle and dual-row ball complement (24 balls) provides excellent rigidity and the ability to withstand significant combined radial and axial loads (Dynamic: 6075 lbf, Static: 5512 lbf).
Precision & Speed Performance: Manufactured to P4A tolerance standards with a phenolic cage, this bearing achieves a high limiting speed of 36,000 rpm. The optimized internal geometry and cage design minimize friction and heat generation at high rotational velocities.
Maintenance-Free Operation: The integrated seals effectively shield the bearing from contaminants, while the pre-applied grease lubrication ensures consistent performance across a wide temperature range (-30°C to 110°C), eliminating the need for re-lubrication in many applications.
