7319 BEM Bearing Product Overview & Core Advantages
The 7319 BEM is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. This precision bearing excels at simultaneously handling significant radial loads and unidirectional axial loads due to its optimized 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and dimensional stability. Its open design, when properly lubricated, facilitates high-speed operation, making it an ideal choice for demanding industrial applications where high rigidity and precise shaft positioning are critical.
7319 BEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| BE | Increased internal clearance and optimized internal design | Enhances performance under specific thermal and load conditions. |
| M | Brass (copper alloy) cage | Provides high strength, excellent guidance, and suitability for high-speed applications. |
7319 BEM Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle is engineered to provide an optimal balance between radial and axial load capacity. The calculated distance from side face to load point (84 mm) contributes to stable moment load support.
High-Speed Capability: The robust brass cage (M suffix) ensures reliable ball guidance and low friction at high rotational speeds, supporting a limiting speed of 4,000 rpm.
Superior Load Ratings: With a dynamic load rating of 37,800 lbf and a static load rating of 33,750 lbf, this bearing is built to withstand demanding combined loads.
Precision Manufacturing: Conforming to P6 tolerance class, it guarantees tight dimensional control (bore: -0.015mm to 0, OD: -0.02mm to 0) for precise shaft running and minimal vibration.
Material Integrity: Components made from chrome steel offer high hardness, wear resistance, and long service life under typical operating temperatures from -30° to 110 °C.
7319 BEM Bearing Typical Application Areas
- Machine Tool Spindles: For high-precision machining centers requiring rigidity and speed.
- Industrial Pumps & Compressors: Handling axial and radial forces in rotating assemblies.
- Gearboxes and Power Transmission Systems: Supporting shafts under combined loading conditions.
- Precision Agricultural and Construction Machinery: In applications demanding robust performance and reliability.
