Product Overview: The 7008 Angular Contact Ball Bearing
The 7008 bearing is a precision-engineered component belonging to our 7000 Series of Single Row Angular Contact Ball Bearings. With dimensions of 40x68x15mm, this bearing is specifically designed to accommodate combined (axial and radial) loads. Its unique internal geometry features raceways in the inner and outer rings that are displaced relative to each other along the bearing axis. This design allows it to support significant axial loads in one direction, making it ideal for applications requiring high rigidity and rotational accuracy.
As a leading supplier of industrial parts, we provide 7008 bearings manufactured to the highest standards. They are essential for machinery where precision and load management are critical. When used in pairs, these bearings can effectively handle axial loads in both directions, offering a versatile solution for complex mechanical systems.
