7205 BEGAP Bearing Product Overview & Core Advantages
The 7205 BEGAP is a single row angular contact ball bearing engineered for precision applications requiring high-speed operation and superior axial load capacity. Designed with a 40° contact angle, this bearing excels at handling combined radial and axial loads simultaneously while maintaining exceptional rotational accuracy. Manufactured to P6 (ABEC-3) tolerance class, it delivers the dimensional stability and running precision essential for demanding industrial equipment. Its optimized internal geometry and nylon cage contribute to reduced friction and quiet operation, making it an ideal solution for high-performance machinery.

7205 BEGAP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway curvatures enable superior axial load carrying capacity while maintaining excellent radial load performance. This design ensures optimal stress distribution across the bearing components.
High-Speed Capability: The lightweight nylon cage minimizes centrifugal forces and reduces friction, allowing for smooth operation at the specified limiting speed of 17,000 rpm. This makes the bearing suitable for high-speed spindle applications.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring precise fitment and consistent performance in precision assemblies.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
