The outer spherical bearing with seat is also called the outer spherical bearing with seat. In the general industrial field, the outer spherical bearing with seat is easy to install because it has its own bearing seat and the bearing seat has sealed the bearing well. Even those who do not know much about the bearing can install the outer spherical bearing with seat on the shaft well.

The outer spherical ball bearing with seat is usually equipped with bolts, which is convenient to be fixed at the place to be fixed. There are also sliding block type and frame type, which are fixed by clamping. There are also cantilever type and suspension type, which are usually equipped with threads, which are convenient to be fixed at the rod end or suspended in the air.

Due to the different designs of different machines and the wide application fields of pedestal bearing, there are many kinds of pedestal outer spherical ball bearings. According to the rough statistics of Xiaobian, there are nearly 100 kinds of NTN pedestal outer spherical ball bearings, four kinds of different materials and five or six sealing methods. Therefore, more than 1000 types are arranged and combined, and each type has many bearing models. Therefore, the model of pedestal outer spherical ball bearings, It can be said to be infinite.

1、 Pillow shaped vertical bearing with seat

Pillow shaped vertical bearing with seat is the most common shape in the bearing seat, with two fixing screws, which is suitable for use in transmission devices and ordinary machinery.

2、 Flange mounted bearing with seat

The shape of the bearing seat is square or round, and there are two, three or four bolts, which are installed on the side wall of the machine through bolts. The flange mounted bearing with seat with retaining cover is suitable for use in the harsh environment of outdoor conveyor, such as wind, rain, sand and stone.

3、 Sliding block bearing with seat

This kind of bearing seat is equipped with sliding groove, which is clamped by the groove in the axial direction and can move in both directions in the radial direction. Therefore, it is very suitable for use in scenes where runout will occur, such as conveyors, conveyors, etc.

4、 Ring bearing with seat

The outer circumference of this kind of bearing seat is circular, so it has certain centering. When the shaft moves non axially and non radially, i.e. rotational runout, this kind of bearing with seat can still operate normally.

5、 Frame bearing with seat

The structure of this kind of bearing is similar to the sliding block bearing with seat. Due to the external frame, it is easier to install without additional sliding groove.

6、 Cantilevered bearing with seat

This kind of bearing is cantilevered. As the name suggests, it is fixed at the rod end, so it has threads and is very suitable for screw conveyor.
