Custom Wind Turbine Yaw Bearing Support Casting OEM Sg Iron Yaw Support

The most critical areas are typically the yaw bearing mounting surface, bolt-hole pattern, concentricity of the bearing interface, and the dimensional relationship between the main mounting surfaces. These features directly affect bearing installation and the alignment of the yaw system, so they are machined and inspected according to the customer's drawings and tolerance requirements.

Dimensional control is carried through both machining and final inspection. Large CNC vertical lathes and gantry machining centers are used for the major circular and mounting surfaces, while dimensional inspection can be performed using equipment such as CMM and laser tracker, depending on the project requirements.

The bearing mounting surface, bolt-hole positions and other critical interfaces are inspected against the approved drawing and specified tolerances. Depending on the project requirements, dimensional inspection can include CMM measurement, laser tracking and other appropriate measurement methods.
