Product Overview: The 7208 Angular Contact Ball Bearing
The 7208 bearing is a high-precision, single-row angular contact ball bearing designed to accommodate combined radial and axial loads. As a key component in our 7200 Series, this bearing is engineered for applications demanding high rotational speeds and exceptional rigidity. Its internal design features a specific contact angle between the raceways and the balls, enabling it to support significant axial loads in one direction. For applications requiring support for axial loads in both directions, these bearings are typically mounted in pairs.
Manufactured to precise industry standards with dimensions of 40x80x18mm (Bore x Outer Diameter x Thickness), the 7208 is a staple in high-performance machinery. As a trusted supplier of industrial components, we provide a comprehensive range of Angular Contact Ball Bearings to meet the rigorous demands of modern industrial applications. Its robust construction ensures reliability and a long service life under challenging operating conditions.
