S71914 CD/P4ATGB Bearing Product Overview & Core Advantages
The S71914 CD/P4ATGB is a precision double row angular contact ball bearing engineered for applications demanding exceptional accuracy and reliability. This sealed bearing is designed to accommodate combined loads, simultaneously handling significant radial loads and bidirectional axial loads. Its compact design, featuring a universal matchable (SU) configuration, allows for flexible mounting arrangements in high-precision systems. Manufactured to the stringent P4A tolerance class and preloaded to Light / Class B, it delivers superior running accuracy, high rigidity, and stable performance, making it an ideal choice for high-speed and high-duty cycle operations.
S71914 CD/P4ATGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S71914 | Basic bearing designation, indicating a double row angular contact ball bearing with a 70 mm bore, 100 mm OD, and 48 mm width. |
| C | Specifies a 15° contact angle, optimized for high axial load capacity and high-speed performance. |
| D | Indicates the bearing is part of a universally matchable (SU) set, allowing any combination of bearings from the set to be mounted together without loss of preload. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy and dimensional stability. |
| TGB | Specifies the use of a phenolic (textile laminate) cage and grease lubrication, contributing to low friction, quiet operation, and suitability for high speeds. |
S71914 CD/P4ATGB Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row design provides superior radial and axial rigidity, enabling the bearing to handle demanding combined loads with high stability. With a dynamic load rating of 16,672 lbf and a static load rating of 22,950 lbf, it is built for longevity under heavy operational stresses.
Optimized High-Speed Performance: The lightweight phenolic cage (T) minimizes centrifugal forces and inertial drag, while the 15° contact angle and precision-ground chrome steel components work in concert to achieve a high limiting speed of 28,000 rpm.
Sealed and Pre-lubricated for Longevity: The integral seals protect against contamination, and the bearing is pre-lubricated with high-performance grease, offering a broad operating temperature range from -30°C to 110°C. This combination provides a long service life with minimal maintenance requirements.
