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

Coined Failure Diagnosis of Slewing Bearings Based on MCKD …

Large-size and heavy-load slewing bearings, which are mainly used in heavy equipment, comprise a subgroup of rolling bearings. Owing to the complexity of the structures and working conditions, it is quite challenging to effectively diagnose the coined failure and extract fault features of slewing bearings. In this study, a method was proposed to denoise and classify …

WES - Fatigue lifetime calculation of wind turbine blade bearings considering blade-dependent load distribution

17/12/2020· Large slewing bearings will, in relation to their size, generally deform more than small bearings. The stiffness of the connected structures such as the blade and hub will highly affect the deformation behavior and lead to large changes in the contact angle of 20 ∘ and more in a highly loaded state (cf. Chen and Wen , 2012 ), which is not considered in any calculation …
