Pillow block insert bearings are special-structured bearings composed of deep groove ball bearings as the base, combined with mounting housings of various shapes on the outside. They are mainly used to bear radial loads.
This type of bearing has a low limiting speed and requires regular grease replenishment during operation; therefore, the outer surface of the bearing housing is usually designed with a grease fitting to facilitate grease injection. Pillow block insert bearings are mainly applied in various types of automatic connection line equipment.
