Slewing Ring Bearing Overhauling

Revolving inspection is necessary to check correct installation after the slewing ring is intalled. For small size machinery, we 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.
