7216 BEGAF Bearing Product Overview & Core Advantages
The 7216 BEGAF is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) tolerance class, delivering exceptional running accuracy and reliability. Its optimized design enables it to handle significant axial loads in one direction simultaneously with radial loads, making it ideal for applications demanding high rigidity and precise rotational characteristics. The bearing comes pre-lubricated and operates effectively within a temperature range of -30° to 110°C.

7216 BEGAF Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 40° contact angle and optimized raceway geometry provide superior stiffness, enabling the bearing to withstand substantial axial loads while maintaining excellent radial load capacity. The calculated distance from side face to load point (59 mm) ensures optimal load distribution and moment load resistance.
Precision Performance: Manufactured to P6 tolerance class (ABEC-3), this bearing delivers exceptional running accuracy and minimal vibration. The precise bore diameter tolerance (-0.012mm to 0) and outside diameter tolerance (-0.015mm to 0) guarantee consistent performance in demanding applications.
High-Speed Capability: The stainless steel cage (F suffix) and optimized internal design contribute to excellent high-speed performance, with a limiting speed of 5,300 rpm. The open design facilitates efficient lubrication and heat dissipation during operation.
Material Quality: Constructed from chrome steel rings and balls with stainless steel cage, the bearing offers excellent durability and wear resistance while meeting ROHS and REACH compliance standards.
