Pillow Block Bearing Types

Pillow Block Bearing Types Introduction:

Pillow block bearing housings can be divided into different types according to different shapes.
Common pillow block bearings types are as below.

1. Pillow Block Bearing Types – Bearing with vertical housing

Vertical housing is the most widely used bearing housing, especially UCP series bearings
For example: UCP

2. Bearing with high center vertical housing

This kind bearing housing is higher than ordinary vertical housing.
For example: UCPA

3. Bearings with square housing

This kind of bearing is mainly suitable for applications where the side surface perpendicular to the shaft is fixed by four bolts. Its fixing method is widely used in machinery. The method of fixing the shaft is the same as that of the bearing with vertical housing.
For example: UCF
