Established in 2022, Jiangsu Manchen Transmission Technology Co., Ltd. is a professional manufacturing enterprise integrating design, research and development, manufacturing, and sales. Located in Huangtu Town, Jiangyin City, Jiangsu Province, our facility benefits from highly convenient transportation access. Relying on exquisite forging, heat treatment, and precision processing techniques, we provide high-load-bearing, high-strength, and long-life transmission solutions.
Our products serve critical fields including construction machinery, medical equipment, intelligent warehousing, environmental protection, industrial robots, and the photovoltaic and concentrated solar power (CSP) industries. Equipped with advanced testing apparatus and a complete quality control system, we provide 100% traceability from raw materials to final delivery, complying with both Chinese and international standards.
Why modern solar thermal projects demand high-precision tracker components to operate under extreme wind, dust, and thermal conditions.
Molten Salt Concentrated Solar Power (CSP) systems represent the vanguard of utility-scale renewable energy storage and generation. Unlike photovoltaic systems, CSP plants utilize arrays of mirrors (heliostats) to concentrate sunlight onto a central receiver tower. Heat-transfer fluid (typically molten salt) circulates through the receiver, absorbing thermal energy to drive steam turbines. Since molten salt requires extremely high temperatures (often exceeding 560°C) to maintain liquid flow and generate high-pressure steam, the precision of solar tracking is paramount.
Any tracking misalignment directly leads to optical spill, rendering the concentrated thermal flux ineffective and potentially damaging the structural elements of the receiver tower. The tracking systems rely on dual-axis slewing drives and slewing bearings to dynamically follow the sun’s trajectory across both azimuth and elevation axes. Manchen Transmission designs components specifically to address these challenges. Our gearless, internal, and external tooth slewing bearings are engineered to handle the constant, low-speed, high-torque micro-movements required for precise tracking over a 25-year service life.
Heliostat arrays situated miles away from the central tower require tracking accuracies within 0.5 to 1.0 mrad. Manchen's precision-ground raceways minimize backlash, ensuring absolute focus.
Concentrated solar fields are typically built in arid, high-wind regions. Slewing drives must sustain massive tilting moments and axial wind loads without structural deflection.
Operating in harsh desert climates demands reliable seal designs to block sand and dust ingress, combined with synthetic lubricants stable across wide temperature fluctuations.
Developing advanced transmission products tailored for next-generation solar tower technologies and industrial scale storage.
The evolution of CSP technology hinges on lowering the Levelized Cost of Electricity (LCOE) while increasing thermal efficiency. Modern plant configurations are expanding heliostat field sizes, which in turn demands larger structural mirrors to reduce the total number of tracking drives. This trend forces a shift in tracking component design from traditional worm-gear systems to integrated slewing drives that display superior torque density and backlash control.
Manchen's technical roadmap focuses on implementing smart diagnostic sensors directly into the bearing raceways. These sensors monitor temperature, vibration, and backlash wear in real-time, feeding predictive maintenance data to the central plant control system. Furthermore, advances in metallurgy and heat treatment (such as double-medium quenching and precise induction hardening) allow us to reduce structural weight while maintaining high load capacities. As global markets transition to carbon-neutral grids, Molten Salt CSP with integrated thermal storage will become a primary baseload energy provider. Our engineering team is committed to continuous optimization to support these utility-scale projects.
Our design capabilities are verified by rigorous testing and deployment feedback in harsh solar-field environments.
Tailored transmission configurations designed to optimize diverse Concentrated Solar Power systems globally.
Dual-axis heliostat fields require azimuth and elevation movements to follow the sun. Manchen’s single-row cross-roller slewing bearings and external tooth drives deliver high axial and moment stiffness, preventing alignment errors caused by heavy wind pressures on large mirrors.
Parabolic trough systems track the sun along a single axis, rotating long loops of parabolic mirrors. Our heavy-duty horizontal rotary drive units and three-row cylindrical roller bearings are designed to support the immense radial and overturning loads of extended trough lines.
Linear Fresnel technology utilizes flat mirrors focusing sunlight on elevated receiver pipes. We supply compact, gearless, and external tooth single-row ball swivel bearings that provide cost-effective, smooth rotation with low startup friction.

Critical considerations when selecting slewing drives and bearings for utility-scale CSP fields.
Procuring components for concentrated solar fields requires balance between performance, durability, and cost. Below are the key design factors that global engineering, procurement, and construction (EPC) companies prioritize:
Technical answers to common questions about slewing bearings and solar tracking drives.
Slewing bearings and integrated rotary drives support dual-axis tracking (azimuth and elevation) from a single mounting point. This design manages tilting moment forces better than linear actuators, making it suitable for large-surface-area heliostats.
We use high-grade forged steel (like 50Mn or 42CrMo) combined with induction hardening on the raceway. Double-lip polyurethane or synthetic seals protect the bearing interiors from sand, dust, and water ingress.
We supply external gear, internal gear, and gearless variants. Our engineering team helps clients select the appropriate option based on motor placement, torque demands, and cleaning space requirements.
Yes. We provide complete customization, adjusting dimensions, gear pitches, mounting holes, seal types, and load-bearing parameters to meet the specifications of your solar tracking system.
We utilize precision CNC grinding machines to control raceway geometries. We also perform rigorous assembly clearances checks using coordinate measuring machines to meet client backlash requirements.
Each bearing and drive receives a unique serial number linked to its raw material chemical analysis, forging reports, heat treatment logs, final dimensions, and inspection records.
