Explore our high-precision L-shaped single-row ball slewing bearings, multi-row cylindrical roller slewing drives, and custom gears engineered for Concentrated Solar Power (CSP) systems, photovoltaic tracker arrays, and heavy industrial machinery.
Concentrated Solar Power (CSP) has transitioned from an experimental renewable asset into a foundational base-load energy alternative. Unlike photovoltaic (PV) modules that directly convert sunlight into electricity, CSP utilizes massive mirrors (heliostats or parabolic troughs) to concentrate thermal energy, heating a transfer fluid (such as molten salt) to drive conventional steam turbines. This thermal energy storage capability guarantees electricity generation even after the sun sets, positioning CSP as a pillar of grid stability.
To achieve high concentration ratios, CSP heliostats must continuously trace the sun's trajectory with extremely high precision. A deviation of just 0.1 degrees can result in complete thermal focal point misalignment. This requirement places intense performance demands on the primary mechanical transmission components: the slewing drives and swivel bearings. In high-exposure desert regions (e.g., western China, the Middle East, and North Africa), these mechanical joints must support massive, wind-vulnerable reflective structures while maintaining sub-milliradian tracking precision over a 25-to-30-year operational lifetime.
Information Gain Perspective: Modern CSP tracking demands specialized metallurgy. Selecting high-grade 42CrMo or 50Mn steel, combined with precision induction hardening of the raceway and specialized gear profiles, prevents local stress concentration and ensures smooth, low-backlash operation under desert wind storms.
Thermal energy storage (TES) capacity is expanding globally, requiring larger heliostat fields and highly resilient dual-axis tracking gearboxes.
Heliostats face extreme ambient temperatures, wind gusts up to 130 km/h, and fine sand particulate intrusion.
Precision positioning requirements dictate slewing drive backlashes below 0.5 mrad (0.02°), requiring high manufacturing tolerances.

CSP solar plants utilize different solar collection technologies depending on geographic constraints and storage needs. Our engineering department designs and manufactures customized rotary solutions for the three primary configurations:
Tower-type CSP plants require thousands of tracking mirrors (heliostats) to reflect solar radiation toward a central tower receiver. Heliostats utilize dual-axis tracking systems (azimuth and elevation) to follow the sun. Our vertical internal gear slewing drives and L-shaped single-row ball slewing bearings provide the stability and precision needed to control backlash, keeping the reflected beam aligned with the receiver over long focal lengths.
Parabolic trough collectors capture solar energy using long curved mirrors that focus sunlight onto a central receiver tube. The collectors track the sun along a single axis (typically North-South). Our heavy-duty horizontal rotary drives support the overturning and torsional moments produced by high winds along the length of the collector structure, protecting the system against structural deformation.
Linear Fresnel systems utilize flat or slightly curved reflectors that track the sun to focus light onto an overhead receiver. Our gearless single-row ball swivel bearings and non-toothed cylindrical roller designs offer cost-effective, low-friction rotation for these space-efficient, flat-configured collectors.
Design Tip for EPC Contractors: When selecting slewing drives for utility-scale projects, ensure your specifications include structural FEA models of the tracking gears under wind loads, along with salt-spray corrosion protection reports (ISO 12944 C4/C5 criteria).
Our ongoing transmission research and development program addresses the performance needs of emerging solar thermal energy technologies.
