7318 BEGAP Bearing Product Overview & Core Advantages
The 7318 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring superior axial load capacity and rotational accuracy. This precision bearing features a 40° contact angle, enabling it to support significant combined radial and axial loads simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The optimized internal geometry and nylon cage contribute to smooth operation at high speeds, making it an ideal solution for demanding industrial applications where reliability and performance are critical.
7318 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | Increased contact angle (40°) | Enhanced axial load capacity and rigidity |
| GA | Light preload | Reduced deflection and improved running accuracy |
| P | P6 tolerance class (ABEC-3) | High precision for demanding applications |
7318 BEGAP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle design provides superior axial load capacity while maintaining excellent radial load performance, making it suitable for combined loading conditions.
