turntable bearing

Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

Turntable bearing is with features of small friction, high limit speed, simple structure, low cost, easy to achieve high manufacturing precision.
The turntable bearing can bear various loads of diameter, shaft and overturning at the same time. It has a firm structure and is especially suitable for heavy-duty machinery with large loads, such as port cranes, molten steel platforms, and shield machines. and other heavy machinery.

1. light weight
2. Can transmit both axial forces and the thrust and pull forces generated during drive.
3. Flexible rotation
4. Can be matched with transmission gears, applied to industrial machines

YRT rotary table bearings can simultaneously withstand comprehensive loads such as axial loads, radial loads, and overturning moments. It is precision bearings with special structures that integrate support, rotation, transmission, and fixation. The turntable bearing basically adopts the design method of negative clearance and preload to ensure the high rigidity and rotation accuracy of the bearing. Turntable bearings have the characteristics of compact structure, high rotation accuracy, easy installation and maintenance, etc
