Product Overview: The 7222 Angular Contact Ball Bearing
The 7222 bearing is a high-precision, single-row angular contact ball bearing designed for applications requiring high speed and rigidity. As a key component in our 7200 Series of Angular Contact Ball Bearings, it is engineered to accommodate combined loads—simultaneously supporting both radial and axial forces in one direction. Its specific contact angle allows for high thrust capacity, making it essential for machinery where precision and stability are paramount. With dimensions of 110mm bore diameter, 200mm outer diameter, and 38mm thickness, the 7222 is manufactured to exacting standards for optimal performance.
These bearings are typically mounted in pairs (back-to-back, face-to-face, or in tandem) to handle axial loads in both directions and to provide a rigid bearing arrangement. As a premier supplier of industrial components, we ensure our 7222 bearings deliver the reliability and longevity required for the most demanding industrial environments.
Key Features of the 7222 Bearing
- High Axial Load Capacity: Designed to support significant axial loads in a single direction, in addition to radial loads.
- High-Speed Capability: Engineered with low-friction characteristics, making it suitable for high-speed rotational applications.
