7213 BEGAP Bearing Product Overview & Core Advantages
The 7213 BEGAP 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 optimized contact angle of 40° provides excellent axial rigidity and load-carrying capacity. Manufactured to P6 (ABEC-3) tolerance class, it ensures reliable performance in high-speed applications up to 6,700 rpm, while the nylon cage contributes to smooth operation and reduced friction.

| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| BE | Increased internal clearance and optimized internal design | Enhanced performance under thermal expansion and high-speed conditions |
| GA | Light preload | Improved rigidity and rotational accuracy for precision applications |
| P | P6 tolerance class (ABEC-3) | High precision dimensional stability and consistent performance |
7213 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. The calculated distance from side face to load point (50 mm) ensures optimal load distribution and moment capacity.
High-Speed Capability: The nylon cage reduces rotational mass and friction, enabling smooth operation at limiting speeds up to 6,700 rpm. This makes it suitable for high-speed applications where reduced vibration and noise are critical.
Precision Engineering: Manufactured to P6 tolerance class with precise bore and outside diameter tolerances, this bearing delivers consistent performance and long service life in precision machinery.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability under demanding operating conditions within the temperature range of -30° to 110°C.
