Single row four point contact ball slewing bearing.
It is composed of two seat rings. It has compact structure, light weight, and four-point contact between steel ball and arc raceway. It can bear axial force, radial force and overturning moment at the same time. The construction machinery of rotary conveyor, welding manipulator, small and medium-sized crane and excavator can be selected.

production flow chart
Raw material → forgings → turning → inspection → heat treatment → grinding → inspection → quenching and tempering → fine grinding → fine grinding → inspection → assembly → assembly inspection → packaging → boxing → transportation → customer.
Material of turntable slewing bearing: 50Mn, 42CRMO,
Turntable slewing bearing accuracy: P0, P6, P5, P4, P2 accuracy from low to high, the price will also from low to high.

 

Slewing bearing use:
1. Trailer: This type of bearing is used in many occasions, the most important of which are used in the transportation industry, agricultural trailers, irrigation systems and airport luggage racks. In the application of the vehicle, the axial load, radial load and torque of the bearing are transmitted. In other applications, they mostly transmit axial loads.
2. Wind power: Wind turbine bearings usually include yaw bearings, pitch bearings, and transmission system bearings (main shaft and gearbox bearings). Yaw bearings and pitch bearings are provided for customers. The yaw bearing is installed at the connection between the tower and the cabin, 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 energy: Rotating solar panels are a good solution to increase energy. Because the bearing has a very compact design, it supplies the largest solar farm in Europe.
4. Medical equipment: The high-precision, low-noise, long-life, and high-reliability series of medical equipment spindle slewing bearings developed by the 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. The slewing bearing is installed on the joints of the robot. This structure can achieve incredibly high-density rotational motion.
The function of slewing bearing
Its function is to connect the upper and lower parts of the machine together, and at the same time to support the weight of the upper part and the load generated when the machine is working, and to make the upper part of the machine rotate relative to the lower part (or the lower part relative to the upper part).
