Explore our foundational transmission and rotary drive mechanisms engineered for global heavy-duty applications, construction machinery, and concentrating heliostat arrays.
The Ivanpah Solar Electric Generating System stands as one of the largest Concentrated Solar Power (CSP) installations in the world. Dynamic, high-accuracy tracking is essential for solar thermal towers. In this design, thousands of heliostats must continuously reflect sunlight toward a central boiler. Achieving this level of precision under extreme environmental conditions demands advanced ODM transmission machinery.
"Precision in CSP tracking directly correlates with thermal output. Even a micro-radian of misalignment can result in substantial energy loss at the central tower collector."
This system relies on robust rotary drive technologies. These units must withstand wind shear, dust storms, and heavy load moments without succumbing to gear play or backlash. High-strength gearless L-type swivel bearings and custom cross-roller slewing systems ensure structural integrity, preventing alignment deviations and maintaining peak power generation capacity.
High-temperature fluctuations (ranging from sub-zero winter nights to desert heat exceeding 45°C) require robust sealing structures and specialized synthetic greases to prevent breakdown.
Heliostats act as large sails in open deserts. Our gearless L-type swivel bearings provide high overturning moment resistance, neutralizing wind forces and protecting drive systems.
Sealing rings made of high-grade fluororubber or polyurethane prevent fine desert dust from entering raceways, reducing friction, wear, and structural degradation over long lifecycles.
Providing high-precision tracking, reducing structural fatigue, and increasing the operational lifespan of Concentrated Solar Power (CSP) and solar tracker installations.
The technical roadmap for CSP rotary drives focuses on increasing precision, extending operational life, and reducing maintenance requirements. Historically, solar trackers used traditional worm gears, which are susceptible to backlash and friction wear. Today's systems utilize a combination of gearless designs and single-row ball-type swivel bearings to optimize drive efficiency.
Future developments aim to integrate smart sensors directly into the bearing housing, allowing for real-time tracking of load shifts, temperature variations, and vibration profiles. This data enables predictive maintenance, reducing field failures and optimizing energy capture across thousands of heliostats.
By utilizing induction-hardened raceways and precision-ground rolling elements, our bearings maintain low rotational torque under high axial loads. This design enhances tracking accuracy and reduces the power consumption of tracking motors, improving overall system performance.

Find answers to common engineering questions regarding the customization, performance, and application of slewing bearings in large-scale heliostat configurations.
Our slewing bearings are designed to meet a 25-year operational lifecycle, aligning with the typical lifespan of modern concentrated solar power plants. We use high-quality alloys (such as 42CrMo or 50Mn) combined with precise induction hardening of the raceways to minimize wear and maintain tracking accuracy over decades.
L-type swivel bearings offer high overturning moment resistance and load support in a compact footprint. The gearless design eliminates gear mesh issues and backlash, reducing mechanical friction. It also allows for direct attachment to high-precision external drive gearboxes.
Our bearings are equipped with double-lip oil seals made of NBR or fluororubber. These seals prevent particulate ingress while retaining internal lubricating grease. Additionally, we offer specialized anti-corrosion surface coatings, such as zinc spraying or chemical plating, to protect against sand abrasion and moisture.
