Triangular flanged roller bearing units consist of a spherical roller bearing mounted in a cast iron housing that can be bolted to a machine wall. They are robust, ready-to-mount units that are assembled, lubricated and sealed at the factory for maximum service life. The simple installation, easy alignment and reliable locking technology of SKF ConCentra units contribute to a smooth operation.
