Product Overview: The 7308 Single Row Angular Contact Ball Bearing
The 7308 bearing is a high-precision component designed to accommodate combined radial and axial loads. As a key part of our 7300 Series, this Angular Contact Ball Bearing features 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 high-speed applications where rigidity and accuracy are paramount. With standard dimensions of 40mm bore diameter, 90mm outer diameter, and 23mm thickness, the 7308 is engineered for superior performance in demanding industrial machinery.
These bearings are designed to handle high axial loads in one direction. Consequently, they are typically adjusted against a second bearing or used in matched pairs (back-to-back, face-to-face, or tandem arrangements) to handle axial loads in both directions and provide a rigid bearing support. Our commitment to quality ensures that every 7308 bearing meets stringent industry standards for reliability and long service life.
