Product Overview and Core Advantages
The 7219 BECBP is a precision angular contact ball bearing designed for applications requiring exceptional performance under combined loads. As a single row bearing with a 40° contact angle, it excels at handling high radial loads and substantial axial loads in one direction simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability, making it ideal for demanding, high-speed machinery where precision and rigidity are paramount.
7219 BECBP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7219 | Standard bearing series designation; 95 mm bore, 170 mm OD, 32 mm width. |
| BE | High contact angle (40°) design, optimized for high axial load capacity. |
| CBP | Indicates a Nylon (Polyamide) cage, contributing to lower friction, quieter operation, and suitability for high-speed applications. |
Structural Features and Performance Benefits
- High Rigidity and Load Capacity: The optimized 40° contact angle and robust chrome steel construction provide high rigidity, enabling the bearing to support significant combined radial and axial loads.
- Superior High-Speed Performance: The lightweight Nylon cage (CBP) minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 4,800 rpm, making it an excellent high-speed bearing.
- Precision Engineering: Manufactured to P6 tolerance with precise dimensional control, ensuring consistent performance, low vibration, and enhanced operational accuracy.
- Optimized Internal Geometry: The specific shoulder diameters on the inner and outer rings ensure precise axial location and optimal load distribution.
