7219 BECBM Bearing Product Overview & Core Advantages
The 7219 BECBM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This precision bearing is designed to accommodate significant axial loads in one direction simultaneously with radial loads, making it ideal for demanding operational environments. Its P6 (ABEC-3) tolerance class ensures exceptional running accuracy, while the optimized 40° contact angle provides excellent axial load capacity. The combination of chrome steel rings, a brass cage, and factory-applied lubrication delivers reliable operation, high limiting speed capability, and long service life in a compact, robust design.
7219 BECBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| BE | Designates an increased contact angle of 40°, providing enhanced axial load carrying capacity. |
| C | Indicates the use of a brass cage (machined window type), offering high strength, excellent guidance, and suitability for high-speed operation. |
| BM | Signifies that the bearing is factory-lubricated with a specific grease suitable for the specified temperature range. |
7219 BECBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to handle high radial and one-direction axial loads simultaneously. The robust chrome steel construction and precise geometry contribute to high system rigidity.
- High-Speed Performance: The brass cage (C suffix) ensures stable operation and low friction at high rotational speeds, supporting the bearing's limiting speed of 6,000 rpm.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class, this bearing guarantees precise shaft positioning, reduced vibration, and smooth running, which is critical for high-precision machinery.
- Ready-to-Install and Lubricated: Supplied pre-lubricated, the bearing is ready for immediate installation, reducing setup time and ensuring optimal initial performance within its designated temperature range.
