Product Overview: The 7220 Angular Contact Ball Bearing
The 7220 bearing is a single-row angular contact ball bearing designed for high-precision applications that require support for both radial and axial loads. With dimensions of 100x180x34mm, this bearing is a key component in machinery demanding high rotational accuracy and speed. Part of the 7200 Series, these Angular Contact Ball Bearings are engineered with a specific contact angle between the raceways and the balls. This design enables them to accommodate significant axial loads in one direction, alongside radial loads. For applications requiring support for axial loads in both directions, these bearings are typically mounted in pairs.
As a specialist supplier of industrial components, we ensure our 7220 bearings meet stringent quality standards, providing the rigidity, speed capability, and reliability essential for modern machinery. Their precision construction makes them indispensable in applications where minimal deflection and high accuracy are critical.
