An insert bearing, also known as a mounted bearing or a pillow block bearing, is a type of bearing designed to be mounted onto a shaft or housing. It consists of a bearing insert (typically a ball or roller bearing) housed in a mounting unit, which may include a housing, sealing elements, and mounting bolts or set screws. Insert bearings are commonly used in various industrial applications where support and rotation of shafts are required, such as conveyor systems, agricultural equipment, and machinery. They provide support for rotating shafts while allowing for easy installation and removal due to their detachable nature. Insert bearings come in various configurations and sizes to accommodate different shaft diameters and loads. They are designed to withstand radial and axial loads and may include features like seals or shields to protect the bearing from contaminants and retain lubrication. Overall, insert bearings are essential components in machinery and equipment, providing reliable support and smooth operation for rotating shafts in a wide range of applications.
