Thin section bearings, slewing ring bearings, bearing remanufacturing - The importance of slewing ring bearing maintenance in lifting equipment

The use of a slewing ring bearing provides yet another benefit: its shaftless design eliminates the need for a spindle or kingpost. The center of the bearing remains open to allow passage of various hydraulic and control components. Since the bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing
