249/1400-MB

The 249/1400-MB is a large-bore spherical roller bearing engineered to perform under the most demanding industrial conditions. With an exceptionally large 1400 mm inner diameter, this bearing is built to support massive rotating shafts and handle extreme loads. Its design features two rows of symmetrical barrel-shaped rollers that align automatically within the sphered outer ring raceway. This self-aligning capability is critical, as it accommodates significant shaft deflection and misalignment relative to the housing, preventing edge stresses and ensuring smooth operation even when precise alignment is not possible.

The primary advantage of the 249/1400-MB lies in its immense load-carrying capacity and durability. The "MB" designation indicates a robust, two-piece machined brass cage, guided by the inner ring, which provides superior strength and reliability in high-load, high-vibration environments. This solid cage construction ensures proper roller guidance and contributes to the bearing's long service life. Because of its ability to manage heavy radial and axial loads in both directions, it is an essential component in heavy machinery such as steel rolling mills, large gearboxes, mining equipment, and pulp and paper processing machinery, where operational reliability is paramount.
