7319 BEGAY Bearing Product Overview & Core Advantages
The 7319 BEGAY is a precision angular contact ball bearing designed for applications requiring exceptional performance under combined loads. Engineered with a single row design and a steep 40° contact angle, it excels at handling high axial loads in one direction while simultaneously supporting significant radial loads. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and is ideal for high-speed, high-rigidity applications such as machine tool spindles and precision gearboxes. Its robust construction from chrome steel and brass cage guarantees reliability and long service life.
7319 BEGAY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Indicates an increased contact angle (40°) for superior axial load capacity. |
| GA | Specifies the internal clearance group for optimal preload and performance. |
| Y | Denotes a special cage design or material, in this case, a brass cage for high-speed stability. |
7319 BEGAY Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized 40° contact angle and robust single row construction provide excellent rigidity, enabling the bearing to withstand heavy combined radial and axial loads.
- High-Speed Performance: The use of a precision-machined brass cage (suffix Y) ensures superior guidance of the balls, reducing friction and enabling stable operation at high rotational speeds.
- Precision Engineering: Manufactured to P6 tolerance, this bearing offers high dimensional accuracy and minimal runout, which is critical for applications demanding smooth and precise rotation.
- Optimized Geometry: The specified shoulder diameters on both the inner and outer rings ensure proper seating and alignment, contributing to the bearing's overall stability and performance.
