Slewing ring bearing is a bearing used in rotary applications to transfer/support axial, radial and torque loads individually or in combination. The bearing consists of rings fitted with threaded fasteners and usually has a gear integrated with one of the rings.
Important lubrication and maintenance procedures for the manufacturer of slewing bearings are included in the operation and maintenance instructions. Failure to follow the instructions may result in failure of bearings, gears, or both. One example is the lack of annual inspection and retightening requirements for slewing ring mounting bolts. Loose mounting bolts can lead to gear meshing mismatches and abnormal bearing loads, which may lead to failure of the rotating platform of the slewing bearing. This kind of unplanned downtime consumes valuable maintenance time, resources and money that are not needed in the first place and could therefore be used for planned maintenance or other functions.
Therefore, the maintenance advice of the manufacturer of the slewing ring is indispensable in the operation and maintenance procedures. In short, the manufacturer of the slewing ring bearing fails to provide reasonable lubrication and maintenance advice, which makes the rotating platform of the slewing ring have hidden dangers in the whole use process.
