What are the main uses of turntable bearings?

Turntable bearing application:

Turntable bearings are widely used. Construction machinery is where turntable bearings are initially and most widely used, such as earth moving machinery, excavators, disintegrators, stackers and reclaimers, graders, rollers, rammers, rock drilling machinery, roadheading machines, etc.

Concrete machinery:

 concrete pump truck, concrete mixing and placing bar integrated machine, belt type placing machine.

Feeding machinery:

disc-type feeder, sand mixer.

Lifting machinery:

wheeled cranes, crawler cranes, gantry cranes, tower cranes, fork lifts, follow cranes, gantry cranes, marine cranes.

Foundation treatment machinery:

impact reverse circulation drilling rigs, rotary drilling rigs, impact rotary drilling rigs, rotary drilling rigs, reverse circulation rotary drilling rigs, positive circulation rotary drilling rigs, long spiral engineering drilling rigs, submersible engineering drilling rigs, hydrostatic piling rigs, piling rigs; construction vessels: dredgers.

Special purpose vehicles:

 bridge inspection vehicles, fire trucks, window cleaning machines, flatbed beam trucks, aerial work trucks, self-propelled aerial work platforms.

Light industry machinery;

beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle management machine, injection molding machine.

Port equipment:

port cranes, front cranes; mining machinery.

New energy equipment:

wind power generation equipment, solar power generation equipment.

Metallurgical equipment:

 Ferris wheel, etc.; airport equipment: airport refueling machine; military equipment: radar, tanks, etc.


palletizing robots, welding robots, manipulators.

Turntable slewing bearing uses:

1. Trailer:

This type of bearing is used in a variety of applications, the most important of which are in the transportation industry, agricultural trailers, irrigation systems and airport luggage racks. In the vehicle application, the axial load, radial load and torque of the bearing are transmitted. In other applications, they mostly transmit axial loads. khrd specializes in manufacturing turntable slewing bearings for trailers.

2.Wind power:

 Wind turbine bearings usually contain yaw bearings, pitch bearings, and drive train bearings (main shaft and gearbox bearings.) KHRD provides customers with yaw bearings and pitch bearings. The yaw bearings are mounted at the connection between the tower and the nacelle, and the pitch bearings are mounted at the root of each blade at the connection to the hub. Each wind turbine uses one set of yaw bearings and three sets of pitch bearings.

3.Solar energy:

Solar energy: Rotating solar panels are a good solution to increase energy. Since KHRD bearings have a very compact design, they supply the largest solar electric field in Europe.

4.Medical equipment:

KHRD bearings developed high precision, low noise, high life and high reliability series of medical equipment spindle rotary bearings, which have been widely used in large medical equipment such as gamma knife, CT machine and MRI machine.


Industrial robots and other equipment. KHRD rotary bearings are installed in the joint part of robots, and this structure can realize incredibly high and tight rotary motion. The role of the turntable bearing It serves to connect the upper and lower parts of the machine together, and is also used to support the weight of the upper part and the load generated when the machine is working, and to rotate the upper part of the machine relative to the lower part (or the lower part relative to going to work).
