The slewing bearing has an unquenched area, which is called the bearing soft zone. In this paper, through the three-dimensional modelling software, considering the factors such as the depth of the quenching layer, a slewing bearing model with bearing soft zone is established. The load distribution of the slewing bearing is calculated by finite element simulation, and the outer ring of the slewing bearing and the bearing capacity of the cage are analysed under four extreme wind conditions. The results show that under continuous extreme loads, the load on the soft zone is very large and the most vulnerable parts of the cage appear at their joints.
