The Introduction Of Pillow Block Bearing

The concept and composition of pillow block bearing

Pillow block bearing is a kind of bearing, which is installed in the cast iron mounting bracket, which is also the shell of the bearing. Table bearings are usually made of grey cast iron, and the table bearing box has a device that allows the housing to be firmly bolted. The inner bearing assembly of bench bearing is usually a kind of soft metal material, such as white metal, and the shell can be split or single shell.

The role of pillow block bearing

The special design structure of the pillow block bearing makes it used for low torque and minimum load, and also for clean environment in industrial environment.

Distinguish between pillow block bearing and bearing pedestal
We need to understand that pillow block bearing and bearing pedestal are not the same equipment. First of all, the bearing pedestal does not contain inner bearings, unlike the bearing on the platform. Secondly,bearing pedestals are widely used in high-load and corrosive industrial environments. A common feature is that the bearing pedestal is fixed on a stable surface to support the shaft of the rotating shaft through the use of casting bolt mounting holes in the base. Table bearings provide a stable and safe housing for some expensive bearings. Special seals are placed at the inlet and outlet of the bearing box to protect the bearing from dust and other external substances.

Application principle of pillow block bearing
Pillow block bearing split housing usually makes bearing replacement and shaft maintenance easier, while unsplit or integral housing is also used in some applications. In some applications, the unclosed form of table bearings is used to provide areas with fewer passages and lower shaft speeds. This is usually because the frequency of maintenance is lower with slower rotating shaft bearings. By using journal bearings on the rotating shaft, the duty cycle of the shaft is greatly increased. Bearings prevent the shaft from deforming and swinging as it rotates, thereby damaging any connecting joints and weakening the structure of the steel shaft. Modern journal bearings use replaceable soft metal bearing housings in cast iron or cast steel bearing boxes, and early versions of equipment occasionally use cast bearings inside the bearing boxes. These types of bearings are usually bearings with short life and need frequent use.
