Product Overview: The 7009 Single Row Angular Contact Ball Bearing
The 7009 bearing is a high-precision component designed for applications that require high rotational speeds and the ability to support combined (axial and radial) loads. As part of our 7000 Series of Angular Contact Ball Bearings, this bearing is engineered with raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This design makes it ideal for handling significant axial loads in one direction, often used in pairs to support loads in both directions.
With industry-standard dimensions of 45x75x16mm, the 7009 bearing provides a reliable solution for various high-performance industrial machinery. Its construction ensures high rigidity and accuracy, making it a critical component in applications where precision is paramount. As a trusted supplier of industrial parts, we guarantee that our 7009 bearings meet stringent quality standards for optimal performance and longevity.
