7419 CBM Bearing Product Overview & Core Advantages
The 7419 CBM is a precision single row angular contact ball bearing designed for applications requiring high rotational accuracy and the ability to support combined loads. Engineered to P6 (ABEC-3) tolerance class, this bearing excels in high-speed operations and offers exceptional rigidity. Its 40° contact angle is optimized to handle significant axial loads in one direction alongside radial loads, making it a compact and reliable solution for demanding machinery.
7419 CBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| C | Designates a standard contact angle of 15° (Note: This bearing has a 40° angle, indicating a specialized design not fully captured by the standard 'C' suffix). |
| B | Indicates a 40° contact angle, which provides higher axial load capacity. |
| M | Specifies the cage material is brass (machined), contributing to high-speed capability, strength, and temperature resistance. |
7419 CBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle provides robust support for combined radial and axial loads. The optimized internal geometry ensures stable operation under heavy loads.
- High-Speed Performance: The brass cage (M suffix) ensures excellent dimensional stability and low friction at high rotational speeds, supporting a limiting speed of 3,400 rpm.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees minimal running vibration and high positional accuracy, which is critical for precision applications.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. The open seal type allows for custom lubrication regimes tailored to specific operational needs.
7419 CBM Bearing Typical Application Areas
The 7419 CBM angular contact ball bearing is ideally suited for high-performance machinery where precision and reliability are paramount. Common applications include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Motors
- Agricultural and Construction Machinery
