Product Overview: The 7211 Angular Contact Ball Bearing
The 7211 bearing is a high-precision component designed for applications requiring high speed and combined load support. As part of our 7200 Series, this single-row Angular Contact Ball 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 allows it to accommodate both radial and axial loads simultaneously. With standard dimensions of 55mm bore diameter, 100mm outer diameter, and 21mm thickness, the 7211 is a versatile solution for a wide range of demanding industrial machinery.
Manufactured from high-quality bearing steel, the 7211 offers exceptional durability and performance. Its internal geometry is optimized for high rotational speeds while maintaining rigidity, making it an excellent choice for applications where precision is critical.
