The difference between slewing ring and ordinary bearing

2022-04-24

The slewing ring is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time. Ordinary bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In different industries, both slewing rings and ordinary bearings are commonly used. Therefore, we must understand the difference between slewing bearings and ordinary bearings before using them. So what's the difference between them? Now let's introduce them.

 

The difference between slewing ring and ordinary bearing

 

The biggest difference between slewing ring and ordinary bearing:

 

1. Usually, the slewing bearing is equipped with a ring gear for rotational driving and a sealing device for dust prevention.

 

2. In terms of materials and manufacturing processes such as heat treatment, slewing bearings are very different from rolling bearings.

 

3. The installation method is different, the slewing bearing is not set on the mandrel and installed in the bearing box like ordinary bearings, but is fixed on the upper and lower supports by screws.

 

4. Slewing bearings generally have to bear several loads, not only axial force and radial force, but also a large overturning moment. Therefore, a set of slewing bearings often plays the role of several sets of ordinary rolling bearings.

 

5. The operating speed of the slewing bearing is low, usually below 50 rpm. In many cases, the slewing bearing does not operate continuously, but only rotates back and forth within the angle, which is equivalent to the so-called "swing bearing".

 

6. The size of the slewing bearing is large, and its diameter is usually 0.4-10 meters, and some have a diameter as large as 40 meters.
