The 6904 bearing's design allows it to handle radial and axial loads in both directions. This versatility makes it suitable for a wide range of applications, from electric motors to gearboxes.
Featuring a steel cage and open design, the 6904 bearing is built for durability and efficient lubrication flow, contributing to a longer service life.
With a reference speed rating of 43,000 rpm and a limiting speed of 26,000 rpm, this bearing is well-suited for high-speed applications. Its design minimises friction, allowing for efficient operation in dynamic environments.
The thin section profile of the 6904 bearing makes it ideal for applications with limited radial space. Its compact size does not compromise performance, making it a preferred choice for precision instruments and smaller machinery.
