Product Overview: The 7311 Angular Contact Ball Bearing
The 7311 bearing is a high-precision, single-row angular contact ball bearing with dimensions of 55x120x29mm. As a key component in our 7300 Series, this bearing is engineered to accommodate combined radial and axial loads simultaneously. Its design features a specific contact angle between the raceways and the balls, enabling it to support high thrust loads in one direction. This makes the 7311 an excellent choice for applications requiring high rigidity and rotational accuracy at high speeds.
Manufactured to exacting industry standards, our 7311 bearings provide reliable performance and a long service life in demanding industrial environments. They are typically used in pairs or sets to handle axial loads in both directions and to provide a rigid bearing arrangement.
