Slewing Bearing for Crane Machine
Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead crane, aerial crane, crane. The slewing bearing used by the crane is mainly heavy-duty slewing bearing, which is required to carry a large axial force and overturning moment. The main function is to support the upper mechanism and control the rotation of the upper mechanism. The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates accordingly.
