Product Overview: The 7309 Angular Contact Ball Bearing
The 7309 bearing is a high-precision, single-row angular contact ball bearing designed to handle significant combined loads. With principal dimensions of 45mm Bore Diameter, 100mm Outer Diameter, and 25mm Thickness, this component is engineered for applications demanding high rotational speeds and rigidity. As part of our 7300 Series, the 7309 features a specific contact angle that allows it to accommodate substantial axial loads in one direction, alongside radial loads. This makes it a crucial component in machinery where precise shaft location and high performance are essential.
Manufactured to exacting industry standards, our 7309 bearings provide superior reliability and extended service life. The design includes raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This configuration makes them ideal for use in pairs to handle axial loads in both directions. Explore our comprehensive range of Angular Contact Ball Bearings to find the optimal solution for your industrial application.
