Discover our top-tier industrial components engineered to provide high load capacity, long-term durability, and precise tracking accuracy under severe environment demands.
In the global quest for clean energy, CSP Electricity (Concentrated Solar Power) represents a paradigm shift. Unlike traditional photovoltaic systems that directly convert sunlight to electricity, CSP utilizes massive mirrors (heliostats, parabolic troughs, or linear Fresnel reflectors) to concentrate sunlight onto a thermal receiver. This heat is then used to drive a conventional steam turbine generator, often paired with thermal energy storage (molten salt systems) to produce dispatchable, base-load renewable power around the clock.
To maximize the concentration ratio and optical efficiency, the solar tracking system must maintain sub-milliradian tracking precision. Over long operational periods, CSP systems are subjected to severe outdoor parameters, including high wind loads, intense desert heat, abrasive sandstorms, and rapid temperature fluctuations. At the heart of these trackers lies the heavy-duty slewing bearing and horizontal rotary drive unit. By providing dual or single-axis rotation with high overturning moment resistance, these components guarantee that heliostats and parabolic collectors precisely follow the sun's trajectory.
As a pioneer in large-scale transmission technology, Jiangsu Manchen Transmission Technology Co., Ltd. is at the forefront of this industrial transformation. We design and manufacture heavy-duty, high-accuracy rotational systems designed to withstand the extreme torques of multi-megawatt CSP installations.

As heliostats and parabolic trough collectors increase in size to capture more solar energy, they expose tracking systems to heightened wind loading, dynamic shear forces, and tremendous overturning moments. Our technical roadmap addresses these engineering challenges through next-generation mechanical features:
Looking ahead, Jiangsu Manchen is investing in Smart slewing drives equipped with IoT vibration and wear sensors, offering real-time health data to plant operators, predicting maintenance intervals, and eliminating unexpected failures.
"We aim to achieve a 15% reduction in total rotary module weight while doubling the static load limit. This permits project developers to scale up individual heliostat surface areas, significantly reducing overall civil foundation costs."
