High-accuracy single-row, double-row, and cross-roller slewing systems engineered for modern heavy-load industrial equipment, solar tracking applications, and industrial automation.
Global energy transition mandates have placed Concentrated Solar Power (CSP) with Molten Salt Thermal Energy Storage (TES) at the forefront of dispatchable utility-scale clean energy. Unlike traditional photovoltaic (PV) power systems which suffer from intermittent output, molten salt solar plants utilize vast arrays of heliostats (mirrors) to focus solar thermal radiation onto a central receiver. Here, molten nitrate salts are heated to temperatures exceeding 560°C to generate high-pressure steam, driving standard steam turbines even in total darkness.
At the center of this engineering marvel lies the requirement for continuous, ultra-precise mechanical movement. Heliostats must track the sun’s path with milliradian accuracy over a typical service life of 25 to 30 years under extreme environmental loads. As a leading manufacturer, Jiangsu Manchen Transmission Technology Co., Ltd. addresses these high-load-bearing, high-strength, and long-life requirements, supplying customized slewing bearings and horizontal rotary drives tailored to CSP tracking systems.
Enabling continuous thermal exchange by facilitating precise heliostat movement, which minimizes temperature fluctuations within the receiver and prevents molten salt freezing or thermal shock.
Our slewing drives feature IP66-rated seals, protecting the internal rolling elements against sandstorms, heavy winds, and high UV radiation common in desert CSP sites.
By employing advanced induction hardening techniques and precision raceway grinding, our products support up to 30 years of trouble-free operations.

EPC contractors and project developers face distinct engineering requirements when sourcing tracking components for high-altitude desert locations.
Requires components surrounding the salt pipes and structures to tolerate high radiation heat levels.
Low backlash design limits optical deviation, keeping focused sunlight precisely on the central receiver.
Ensures minimal downtime and long-term return on investment for capital-intensive CSP infrastructure.
In regions like the MENA (Middle East and North Africa), South America (Atacama Desert), and Northwestern China, CSP solar plants are subjected to intense wind shear and thermal fluctuations. Sourcing managers look for suppliers capable of providing certified 42CrMo or 50Mn steel slewing rings with deep induction-hardened raceways to handle large tilting moments. Jiangsu Manchen's precision-manufactured horizontal rotary drives and slewing rings address these parameters, ensuring reliable torque output under continuous load cycles.
Slewing bearings and drive systems serve as the mechanical backbone for distinct Concentrated Solar Power configurations.
Heliostat fields demand dual-axis tracking where two coordinated drives or a single combined drive adjust the azimuth and elevation angles. The primary challenge is maintaining alignment during high gusts. Jiangsu Manchen's gearless single-row ball and cross-roller bearings are engineered to handle high radial and tilting loads, providing high stiffness in compact structures.
Parabolic trough systems concentrate sunlight onto a receiver tube running along the reflector's focal line. These collectors track the sun on a single axis (typically North-South). Heavy collector assemblies require robust, low-maintenance single-row ball slewing bearings with internal or external gearing to support steady, continuous movement.
Linear Fresnel plants use long, flat mirror segments to focus light on an elevated receiver. The rotation of individual slats requires reliable L-type or lightweight gearless bearings. Our cost-effective, high-volume production capabilities enable uniform precision across hundreds of tracking lines.
Our ten-step production cycle ensures reliability, traceability, and precision for every slewing ring and drive system leaving the factory.

The Concentrated Solar Power landscape is shifting toward higher-temperature molten salts (utilizing chloride or carbonate salts) and supercritical CO2 power cycles. These advancements aim to elevate thermodynamic efficiency and drive operating temperatures past 700°C. While this progression boosts generator output, it places higher demands on adjacent tracking support assemblies.
Jiangsu Manchen's engineering department is addressing these challenges through research into three primary areas:
Jiangsu Manchen operates under strict international quality guidelines, ensuring reliability and mutual cooperation across every project.
We support developer requirements from prototype drafting through to volume manufacturing.
Every commercial solar thermal installation presents specific requirements. Factors such as localized wind speeds, soil-bearing capacity, heliostat configuration, and weight distribution impact component selection. Jiangsu Manchen Transmission Technology Co., Ltd. provides comprehensive OEM and ODM support, tailoring slewing rings and drive mechanisms to custom dimensions, gear profiles, and load characteristics.
Our engineering team utilizes finite element analysis (FEA) to simulate complex load profiles. By modeling wind loads and structural moments, we verify component safety and performance before production begins. This process optimizes material allocation, ensuring durability under real-world conditions without inflating project budgets.
We collaborate with EPC engineering departments to review drawings, evaluate backlash tolerances, and configure sealing solutions.
Our manufacturing lines support low-volume prototype builds, allowing physical testing and validation in test fields before full project rollout.
We match technical execution with regional regulatory certifications to ensure smooth project implementation.
Jiangsu Manchen manufactures slewing bearings to comply with international regulatory frameworks and standards, including ISO 9001:2015, CE directives, and standard steel inspection certificates. Our raw material sourcing relies on major Chinese steel mills with full heat treatment traceability. This ensures compliance with structural specifications and mechanical property requirements for projects in Europe, North America, and Australia.
Our location in Jiangyin City offers convenient access to key maritime transport networks in Shanghai and Ningbo, enabling reliable delivery schedules for heavy-machinery components. We pack all slewing bearings with heavy-duty anti-corrosion grease and vacuum wrapping to protect against marine humidity during transit, ensuring components arrive clean, functional, and ready for installation.
