Pillow block bearing units are usually housed bearings with a machined mounting surface and are used in mechanical power transmission systems to support shafts and couplings. The shaft is parallel to the mounting surface and generally perpendicular to the mounting screws. They are a type of housed-bearing unit. These could have different bearings, such as ball bearing, cylindrical bearings, tapered rollers or synthetic bushings. They are crucial components in various machinery, ensuring shafts remain in position and operate smoothly
