Bearings for Wind Turbine

bearing and housing are optimized by calculating the bearing life, including housing deformation and bearing clearance and also confirming the housing strength based on a stress analysis. In this example, a bearing for 1.5-MW wind turbines was used, and the maximum deformation in the axial direction was 0.07mm. The difference in the bearing

Slew bearing failure analysis - Kavitsu Bearings

The durability of the slew bearings who have undergone improper induction heat treatment are more prone to failure in early stages of the operating cycle. If this occurs, the bearing must be replaced or repaired immediately, as by not doing so, pitting will be more and that might result into jamming of rolling elements inside the bearing.

Understanding Journal Bearings - EDGE

bearings are split and rotor removal is not required to inspect and replace. While split rolling element bearings are also available they are costly and not common. Journal bearing fatigue damage is usually visible at an early stage and allows for better diagnostics of failure modes so that corrective action can be taken to prevent recurrence.
