7220 BEGAM Bearing Product Overview & Core Advantages
The 7220 BEGAM is a single row angular contact ball bearing engineered for applications demanding high precision and robust performance under combined loads. Its defining characteristic is the 40° contact angle, which provides superior axial load carrying capacity in one direction while accommodating significant radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures exceptional running accuracy and rotational stability, making it ideal for high-speed spindles and other precision machinery. The combination of chrome steel rings and a brass cage delivers high rigidity and reliable operation, establishing the 7220 BEGAM as a critical component for high-performance systems.

| BE | Designates a 40° contact angle and optimized internal geometry for high axial load capacity. |
| GAM | Indicates the bearing is supplied lubricated with a specific high-performance grease suitable for the specified temperature range. |
7220 BEGAM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is engineered to handle high combined loads, providing excellent thrust capacity and radial support. The optimized shoulder diameters on both rings ensure secure seating and maximum support for the rolling elements.
- Precision and High-Speed Performance: Manufactured to P6 tolerance, the bearing guarantees minimal runout and vibration. The brass cage contributes to smooth operation and stability at the high limiting speed of 5,600 rpm.
- Durability and Reliability: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. The pre-applied lubrication ensures immediate, reliable operation upon installation within a temperature range of -30° to 110 °C.
