Yaw Bearing and Blade Bearings (Internal Gear)

PMK Yaw and Blade Bearings with Internal Gear integrate the slewing drive within the bearing to achieve compact, efficient motion transmission for wind turbine systems.

The internal gear design enables smooth torque transfer while protecting the gear teeth from environmental exposure, ensuring long-term operational stability.

Key benefits

Integrated internal gear for compact yaw and pitch drive systems.
High load capacity with excellent rigidity and stability.
Reduced wear and noise due to optimized gear meshing.
Protected gear interface enhances durability in outdoor use.
Ideal for space-limited nacelle or hub designs.

Applications

Wind turbines and renewable energy platforms.
Large rotating machinery with enclosed drives.
Industrial cranes, solar trackers, and marine rotation systems.
Automation and energy conversion assemblies.
