Yaw Bearing and Blade Bearings (External Gear)

PMK Yaw and Blade Bearings with External Gear are designed for high torque transmission and heavy-duty rotation in wind turbines and large-scale machinery. The external gear arrangement enables simple drive integration, efficient torque transfer, and easy maintenance access while delivering high structural rigidity and reliable rotation.

Key benefits

High torque transmission via external gear design.
Excellent load-carrying capacity and structural rigidity.
Smooth, precise motion under variable wind or mechanical loads.
Easy drive engagement and service accessibility.
Durable surface treatment for outdoor and offshore conditions.

Applications

Wind turbine yaw and blade systems.
Offshore cranes, radar, and large turntables.
Renewable energy and heavy rotating installations.
Construction and industrial machinery with gear-driven rotation.
