The UCF series features a square flanged bearing housing that is secured via four bolts to a mounting surface perpendicular to the shaft (such as the side wall of a machine or the end face of a housing). The bearing axis is perpendicular to the mounting surface, making this series suitable for applications where mounting from beneath the base is not possible and the shaft must be secured from the side. Pillow Block Bearing is a bearing unit combined roller bearing and housing together. Most of the outer spherical bearings are made outer diameter sphere, installation and imported bearing bore together with a spherical structure forms, versatility and interchangeability.
