The rotary table bearing pedestal is a large and extra-large bearing pedestal that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and convenient device maintenance. Compared with ordinary bearing blocks, the rotary table bearing block has the following obvious features:

1. Overall dimensions

The diameter usually ranges from 0.4cm to 10m and can reach up to 40m.

2. High carrying capacity

Generally, axial load, radial load, and overturning moment load can be accepted together.

3. Low rotational speed

The task rotation speed is lower than 10 r/min, and in a few cases, it does not perform continuous rotation, but only rotates within a certain angle and performs a swing motion.
