Turntable bearing is a kind of bearing that can bear the comprehensive loads such as axial load, radial load and overturning torque at the same time. It is a precision bearing with special structure integrating the functions of support, rotation, transmission and fixation. The turntable bearing basically adopts the design method of negative clearance belt pre tightening to ensure the high rigidity and rotation accuracy of the bearing.
Generally, the inner and outer rings of the turntable bearing are equipped with installation holes, lubricating oil holes and sealing structures, which are suitable for different installation and use needs of various equipment under precision working conditions; Turntable bearings have the characteristics of compact structure, high rotation accuracy and simple installation and maintenance. Turntable bearings mainly include YRT turntable bearings, zkldf turntable bearings and cross roller bearings.
These three series bearings have the same installation size, different internal structure and similar performance.
