Product Overview: The 7004 Angular Contact Ball Bearing
The 7004 bearing is a high-precision, single-row Angular Contact Ball Bearing designed for high-speed applications requiring support for combined radial and axial loads. As a key component in our 7000 Series, this bearing features raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This design makes it ideal for applications where rigidity and precise rotational accuracy are essential. With standard dimensions of 20mm bore diameter, 42mm outer diameter, and 12mm thickness, the 7004 is engineered to provide exceptional performance and reliability.
Angular contact ball bearings are specifically designed to handle axial loads in one direction. For applications involving axial loads in both directions, these bearings are typically mounted in pairs (back-to-back, face-to-face, or in tandem). Our commitment to quality ensures that the 7004 bearing meets stringent industry standards, making it a dependable choice for a wide range of demanding industrial and mechanical systems.
