7208 BEGAY Bearing Product Overview & Core Advantages
The 7208 BEGAY is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. This precision bearing excels in handling significant axial loads in one direction in addition to radial loads, thanks to its optimized 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational stability. Its compact design with 40mm bore, 80mm OD, and 18mm width makes it ideal for space-constrained applications demanding high reliability and precision.

7208 BEGAY Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The optimized internal geometry with 40° contact angle provides exceptional stiffness and enables handling of substantial combined loads (radial and axial). With dynamic load rating of 8212 lbf and static load rating of 5850 lbf, this bearing delivers reliable performance in demanding applications.
Precision Performance: Manufactured to P6 tolerance class with precise dimensional control (bore tolerance: -0.01mm to 0), ensuring smooth operation and minimal vibration. The brass cage provides excellent guidance and stability at high speeds.
High-Speed Capability: Designed for limiting speeds up to 11,000 rpm, making it suitable for high-speed applications. The optimized cage design and precision manufacturing contribute to stable operation at elevated rotational speeds.
Material Excellence: Constructed from chrome steel for both rings and balls, providing superior hardness, wear resistance, and fatigue life. The bearing comes pre-lubricated for immediate operation and operates within a temperature range of -30° to 110°C.
