Under normal circumstances; the slewing bearing itself has equipment holes, smooth oil holes and sealing equipment; can meet the different needs of various types of mainframes operating under different working conditions, on the other hand; the slewing bearing itself has a compact layout, It is convenient for guiding rotation, simple equipment and simple protection; it is widely used in medium and large reversing equipment such as lifting and transporting machinery, metallurgical machinery, mining machinery, construction engineering machinery, port machinery and automated assembly line.
PRS slewing bearings can be divided into four different contact ball slewing bearings, double row ball slewing bearings, interspersed cylindrical roller slewing bearings and three rows of cylindrical roller slewing bearings according to different layout methods. All kinds of bearings are divided into non-toothed, externally-toothed and internal-toothed different layouts according to whether they can be toothed or toothed.
According to different layout characteristics, the slewing bearing can not be satisfied with the needs of the main machine under different load conditions. In the meantime, the four-point contact ball slewing bearing has high dynamic load ability; the inserted cylindrical roller slewing bearing has higher static Load capacity; three-row cylindrical roller combination slewing bearing leads to the height direction of the bearing due to the advancement of bearing capacity; the various loads are accepted by different raceways and roller groups; therefore, under equal force conditions; The diameter can be greatly reduced. 蚨哂惺 骰舸盏 骰舸盏 骰舸盏 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且
The code of the slewing bearing indicates that the bearing code of the first and the code number consists of the root code and the post code.
Second, the composition of the fundamental code is divided into three parts; the front part is the layout type and the transmission type code; the middle part is the roll diameter (the maximum roll body diameter for the bearings of two rows or more of the roll body); the rear part is the middle of the roll body Round diameter (bearings for two rows or more of rolling elements are the largest diameter of the intermediate body of the rolling body)
