What machinery are slewing bearings (slewing bearings) used on?

The slewing bearing is a large bearing with a special structure that can simultaneously bear large axial load, radial load and overturning moment and other comprehensive loads, and integrates multiple functions such as support, rotation, transmission and fixation. Generally speaking, the slew plate bearing itself has mounting holes, lubricating oil and sealing devices, which can meet the different needs of various types of hosts working under different working conditions; on the other hand, the slew plate bearing itself has a compact structure and guides rotation. With the characteristics of convenience, easy installation and easy maintenance, it is widely used in large-scale rotating devices such as lifting and transportation machinery, excavators, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers.

Slewing bearings can be roughly divided into the following structural types according to different structural types:

1. Four-point contact ball slewing bearing

2. Double row four-point contact ball slewing bearings

3. Crossed cylindrical roller slew bearings

4. Crossed tapered roller slew bearings

5. Three rows of cylindrical roller combination slew bearings

Purpose of turntable slewing bearing:

1. Trailers: 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. Application on vehicles, transmitting axial load, radial load and torque of bearings. In other applications, they mostly transmit axial loads. Jinyuan specializes in manufacturing slewing bearings for trailers.

2. Wind power: Wind turbine bearings usually include yaw bearings, pitch bearings, and transmission system bearings (main shaft and gearbox bearings). Jinyuan provides customers with yaw bearings and pitch bearings. The yaw bearing is installed at the connection between the tower and the cockpit, and the pitch bearing is installed at the connection between the root of each blade and the hub. Each wind turbine uses one set of yaw bearings and three sets of pitch bearings.

3 Solar: Rotating solar panels are a great solution for increasing energy. Because Jinyuan Bearing has a very compact design, it supplies the largest solar farm in Europe.

4. Medical equipment; The high-precision, low-noise, high-life, and high-reliability series of medical equipment spindle turntable slewing bearings developed by j Jinyuan Bearing have been widely used in large medical equipment such as gamma knives, CT machines, and nuclear magnetic resonance machines. .

5. Robots: industrial robots and other equipment. Jinyuan turntable slewing bearings are installed at the joints of the robot. This structure can achieve incredibly high-precision rotational motion.
