Housed bearing is a general term. Its usage varies depending on the usage environment (parts). The main categories are: P block (such as UCP), F, FL, T, FC, PA, PH, PB, FB, FC, FU, CC and other types. Bearings with seats are mainly composed of spherical bearings and different types of valve seats. After special tooling, the bearing and valve seat are installed together, which is a semi-separated unit. The outer spherical bearing with seat has been added with lubricating oil customized according to customer requirements before leaving the factory, and the grease nipple, grease nipple cover and wrench are attached with the goods, which is convenient for customers to install.

It is mainly used to bear combined radial and axial loads mainly based on radial loads. Generally, it is not suitable to bear the axial load alone. This type of bearing can be equipped with inner ring (full set of rollers and cage) and outer ring respectively.

Among them, UCP pillow block bearings are the most widely used.
