Explore our heavy-duty internal gear, gearless, and cross-roller slewing solutions engineered for structural longevity and micro-radian tracking precision.
Concentrated Solar Power (CSP) tower technologies rely on thousands of ground-based mirrors, known as heliostats, to reflect and concentrate direct normal irradiation (DNI) onto a central receiver located atop a high tower. The overall thermal and operational efficiency of the system is heavily dependent on the mechanical tracking precision of these heliostats. Even a minor tracking error of 1 milliradian can result in a significant displacement of the reflected solar beam at the central receiver, leading to energy loss, structural thermal fatigue, and reduced power generation.
To optimize the solar power tower efficiency, developers require advanced OEM and ODM engineering solutions capable of delivering high-load capacity and zero-backlash rotational control under extreme desert conditions. Precision transmission assemblies, specifically designed cross-roller slewing bearings, and robust single-row ball swivel configurations play a crucial role in eliminating unwanted tracking jitter caused by crosswinds, thermal deformation, and heavy mechanical payloads.
Heliostat assemblies are subjected to continuous atmospheric exposure, fluctuating wind loads, and rapid thermal cycling. To address these vulnerabilities, high-quality manufacturing facilities utilize optimized transmission engineering practices that focus on three key variables:
By choosing a specialized transmission manufacturer with mature technical processes, CSP operators can substantially reduce maintenance overheads and achieve an operational lifecycle exceeding 25 years.

Slewing bearings provide the mechanical pivot point for heliostats. Minimizing rotational backlash and maintaining structural stiffness under wind loads keeps the reflected solar beam aligned with the central receiver. This precision maximizes heat absorption at the receiver, driving up overall thermal-to-electric conversion efficiency.
Cross-roller slewing bearings arrange cylindrical rollers perpendicularly to one another, allowing them to support radial, axial, and tilting moment loads simultaneously. This design offers higher stiffness and lower rotational friction, making it ideal for large-scale mirrors that experience variable forces and require high-accuracy tracking.
To provide an optimized design, we need details on your maximum axial and radial loads, overturning moments, gear ratio preferences, backlash targets, environment conditions (such as temperature ranges and dust exposure), and interface dimensions.
We use specialized lip-seals, synthetic greases designed to resist high operating temperatures, and anti-corrosion surface treatments (compliant with C5-M specifications). These features keep particles from entering the raceways, extending bearing life in desert areas.
Jiangsu Manchen is ISO 9001:2015 certified. Our products are fully traceable from raw forging to final dispatch, and they conform to both Chinese domestic industrial standards and global requirements (such as DIN and ASME).
