Slewing Drives in Renewable Energy: Powering the Movement Behind Green Technology

What Is a Slewing Drive?

A slewing drive is a complete, compact rotary actuator system that integrates a slewing bearing with a driving mechanism—commonly a worm gear or spur gear—along with housing, seals, and input options for electric, hydraulic, or planetary motors. Slewing drives enable rotational movement and load support with high torque transmission and positioning precision.

In the renewable energy industry, particularly solar tracking and wind power applications, slewing drives play a critical role by enabling panels, reflectors, and turbines to precisely follow the sun or wind direction. This movement ensures optimal energy capture throughout the day and significantly improves energy efficiency.

Why Renewable Energy Needs Slewing Drives

With increasing global demand for sustainable energy, the efficiency of solar and wind systems is paramount. The slewing drive addresses several engineering and economic pain points in this sector:

Precision Tracking for Solar Panels

Solar photovoltaic (PV) and concentrated solar power (CSP) systems use slewing drives to rotate on single or dual axes to follow the sun’s position across the sky. This boosts energy generation by up to 40% compared to fixed-tilt systems.

High Load Capacity in Harsh Conditions

Outdoor environments expose components to wind, dust, humidity, and extreme temperatures. Slewing drives used in renewables must be sealed (IP65+) and capable of handling static and dynamic loads under high torque.

Compact and Integrated Design

Given limited space on panel racks or turbine towers, slewing drives offer an all-in-one solution. Their self-locking worm gears also prevent back-driving in windy conditions without the need for extra braking systems.

Low Maintenance, Long Lifespan

Reliable renewable systems must operate with minimal service. Quality slewing drives, like those produced by LDB, offer grease-filled, factory-sealed housings that minimize lubrication and reduce downtime.

Slewing Bearings for Solar Trackers: Precision and Durability for Maximum Sunlight Capture

What is a Slewing Bearing in Solar Tracking Systems?

A slewing bearing in solar trackers is a large-diameter rotational bearing that enables the controlled movement of photovoltaic (PV) or concentrated solar power (CSP) panels. Installed at the core of single or dual-axis solar tracking systems, slewing bearings allow solar modules to follow the sun’s path throughout the day—maximizing energy yield by maintaining optimal exposure.

These bearings accommodate axial, radial, and tilting moment loads, making them ideal for supporting the structural motion and stability required in dynamic solar environments.
