7319 BECBY Bearing Product Overview & Core Advantages
The 7319 BECBY is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This metric bearing features a 40° contact angle, optimized for handling significant axial loads in one direction while simultaneously supporting radial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational precision. The brass cage construction ensures reliable operation at high speeds, making it an ideal solution for demanding industrial environments where high rigidity and operational reliability are critical.
7319 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Significance |
|---|---|---|
| BE | Increased internal clearance and optimized internal design | Enhanced performance under thermal expansion and high-speed conditions |
| CB | Specific internal clearance and contact angle combination | Optimized for combined load capacity and precise axial positioning |
| Y | Special dimensional, tolerance, or design features | Customized performance characteristics for specific application requirements |
7319 BECBY Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precision-ground raceways provide superior axial load capacity while maintaining excellent radial load performance. The calculated distance from side face to load point (84 mm) ensures optimal load distribution and moment load resistance.
High-Speed Capability: The brass cage offers excellent dimensional stability and wear resistance, contributing to the bearing's limiting speed of 4,300 rpm. This makes it suitable for high-speed spindle applications where thermal stability is crucial.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, the bearing delivers high fatigue resistance and long service life. The open design allows for customized lubrication schemes to match specific operational requirements.
Precision Engineering: With P6 tolerance class and tight dimensional tolerances (bore: -0.015mm to 0, OD: -0.02mm to 0), this bearing ensures precise shaft positioning and minimal runout, critical for high-precision machinery.
7319 BECBY Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers and grinding spindles requiring accurate axial positioning
