Flange mounted units are used both in light and heavy-duty industries ranging from food processing to construction sites. Flange units are offered in cast iron, stainless, thermoplastic, and ductile material configurations. These units can come with a variety of shaft locking options, including, set screw, eccentric locking collar, concentric locking collar, adapter. Set screw units have two set screws 120° apart in the inner ring. The three seal types available are trash seals, shielded, or regular seals. Flange configurations are utilized in applications in which the shaft is perpendicular to the surface. Flanged units come in two and four bolt configurations. Flange units help certify that the bearing is flush to mounted surface while also providing rigidity.
Mounted bearings, sometimes called bearing units or bearing blocks, have a bearing installed in a housing to ease installation and provide additional support for the bearing. They are face or surface mounted in applications where the shaft is perpendicular to the unit. Bearing inserts are used to replace worn or damaged bearings in an existing bearing housing. Collar bearings support high axial loads and limit radial movement. A flange helps ensure that the bearing is flush and provides added rigidity. Pillow-block (Plummer block) bearings attach to a vertical or horizontal surface to support rotating shafts and with light to moderate loads, such as in conveying and other operations where the shaft passes through the bearing. Take up bearings are used to align track and tension conveyor belts.
