Structural characteristics and series models of precision slewing bearing
- 2022/9/14 9:11:40
Precision slewing bearing is a medium and large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. In general, the precision slewing bearing itself has mounting holes, lubricating oil holes and sealing devices, which can meet the needs of different working conditions; on the other hand, the precision slewing bearing itself has the advantages of compact structure, convenient guiding and rotation, easy installation and maintenance. It is widely used in precision marine equipment, precision grinders, lathes, gear shapers, laser chucks, medical equipment rotary tables and indexing discs, machine tools, radar, wind power generation and tank turrets and other devices.
According to the structure of rolling elements, precision slewing bearing is divided into two series: crossed roller slewing bearing and four-point contact ball slewing bearing. Install the seal, match the oiling cup, adjust the torque in a small range, and the accuracy can reach the level of P5/P4/P2 to meet the needs of various working conditions.
