High Load Capacity Crane Slewing Bearing Manufactured In East China

The highest loads and tilting moment are the major characters for three row roller slewing bearing.

Installing slewing bearing surface should be smooth and clean, to remove all excess substances such as paint residue, welding beads, burrs and so on. When cleaning, be careful not to let the solvent penetrate into the inside of the slewing bearing, and do not use the solvent that damages the sealing material. Before installation, the surface should be dry and lubricant free. Measures should be taken to protect workers and the environment.

The roughness of the mounting surface of the mounting support is not greater than Ra=12.5,6.3 micron. The flatness error of the mounting surface must be detected by circumferential error and radial error. The circumferential planeness tolerance value corresponds to the standard value range with the diameter of the raceway of the slewing bearing.

The circumferential flatness error can only undulate once in any 180 degree range, and the variation is gentle, in order to avoid the local overload caused by the unevenness of the installation plane or the deformation of the bearing.
