The world in motion – where are slewing bearings used?
Longwei slewing bearings prove themselves as important mechanical components in very diverse areas of applications. The applications and products are as varied as the slewing bearings themselves: they are individually designed and manufactured for each application. Find out which solutions are available in each industry:

Which Industries and Equipment Can Slewing Bearings Be Used In?

Slewing ring bearings have unique load-bearing characteristics and are usually used in hoisting machinery, excavators, slewing tables, wind power generators, telescopes and tank turrets. Through the improvement of processing methods and the renewal of design concepts, slewing bearings can be applied to occasions with smaller dimensions, more complex structures and more precision.

In the machine tool industry, the slewing bearing of the standard structure adopts high-precision grades and applies preload to eliminate clearance and reduce vibration. The radial runout and diameter tolerance range of the bearing are within the controllable design range, the structure is compact, the cross-sectional size is small, and the diameter size can be as small as 50 mm, which prompts designers to reconsider the traditional bearing configuration.

Slewing bearings are used in crane bearings, crane bearings, bucket wheel bearings, marine crane bearings, shield machine bearings, ladle large bearings, and other turntable equipment bearings that are subject to radial, axial, and moment loads.

Slewing bearings are widely used. Construction machinery is the initial application field of slewing bearings and is also widely used, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compaction machines, rock drilling machinery, roadheaders, etc.
