Overhauling for Slewing Ring Bearing

Revolving inspect is necessary to check correct installation after the slewing bearing is intalled. For small size machinery, can revolve the slewing bearing by hand, to ensure whether can run smoothly. Inspection items include revolving not smoothly due to foreign objects, bruises and indentation; moment force unstable due to unproper installation and unproper processing of support; over moment force due to backlash too small, installation error and sealing friction. If there is no abnormal status, dynamic run of the slewing bearing can be proceeded.
