Discover our ultra-precise, high-torque rotary units and heavy-duty load slewing bearings specifically built to handle intense wind loads and high-precision single-axis tracking requirements.
Linear Fresnel Concentrated Solar Power (CSP) systems rely on long, thin segments of mirrors that focus sunlight onto fixed overhead receiver tubes containing a heat-transfer fluid. To maximize thermodynamic cycle efficiency, these mirrors must track the sun’s daily movement with exceptional precision. Standard tracking systems must exhibit less than 0.1° of angular error under variable field conditions. At the core of these tracking configurations are precision slewing bearings and horizontal rotary drives, engineered to transmit motor power into steady, micro-step movements.
Unlike parabolic trough or tower systems, Linear Fresnel reflectors are positioned close to the ground, minimizing wind load profile. However, their sheer horizontal length means that thermal expansion and torsional stress are significantly high. As a premier Fresnel CSP manufacturer & factory, we realize that solar plant efficiency is directly proportional to tracking stiffness. Our gearboxes and horizontal rotary drive units are designed specifically to withstand high radial, axial, and overturning moment forces, ensuring clean optical alignment throughout the 25+ year lifecycle of the CSP plant.
The company is located in Huangtu Town, Jiangyin City, Jiangsu Province, with very convenient transportation. The company has mature technical conditions and advanced equipment. Relying on exquisite forging, heat treatment and precision processing techniques, we can provide high-load-bearing, high-strength and long-life transmission solutions for construction machinery, medical equipment, intelligent warehousing, photovoltaic industry, port machinery, industrial robots, environmental protection equipment and other fields.
The company is equipped with advanced testing equipment and a complete quality control system. The products have a complete traceability from raw material selection to final product delivery, meeting domestic and international industry standards. The company always adheres to the business philosophy of "quality first, mutual cooperation", providing high-quality services and reliable products to new and old customers.





As international utility-scale solar projects expand across the Middle East, North Africa (MENA), Western China, Spain, and the Southwestern United States, global EPC contractors require unified standard parts that guarantee performance in harsh arid environments.
Fresnel CSP plants are heavily situated in high-DNI desert environments. Our slewing systems utilize specialized double-lip FKM seals and IP66/IP67 rated enclosures to ensure that micro-sand, particulate dust, and high temperatures up to 70°C do not degrade inner rolling elements or cause grease leakage.
Whether your project leverages flat mirror configurations with L-shaped brackets, or integrated gear drives with direct motor inputs, our engineering team constructs bespoke structural mounting layouts, gear ratios, and heat treatment levels matching your precise technical calculations.
Wind loads pose the highest risk of structural failure in linear receiver collectors. Our double-row equal-diameter ball and cross-roller slewing rings exhibit exceptional rigidity to counter overturning moments, ensuring continuous power generation even during intense desert winds.
Our production facility is equipped with state-of-the-art heat treatment and CNC grinding infrastructure. We guarantee full material traceability and structural integrity through every phase of the manufacturing process.
The company has always adhered to the business philosophy of "quality first, mutual cooperation and win-win", providing high-quality services and reliable products to both new and existing customers.
As the Concentrated Solar Power (CSP) sector pushes toward higher steam temperatures (supercritical CO2 cycles and advanced molten salt setups), the requirements on collector fields become more stringent. Higher operating temperatures require taller collector stands, causing increased susceptibility to high wind conditions. Under our long-term R&D roadmap, Jiangsu Manchen Transmission Technology is continually upgrading materials and internal geometries to address these challenges.
1. Zero-Backlash Slewing Drives: Utilizing advanced enveloping worm gear geometry, we aim to decrease backlash to <0.02°, allowing mirror trackers to maintain focus on the receiver tube even during heavy gusts.
2. Eco-Friendly Lubricants for Extreme Environments: Developing solid-film and synthetic long-life lubricants that maintain viscosity at +80°C and resist solidification down to -40°C.
3. Direct-Drive Integrations: Transitioning typical multi-stage gears into high-efficiency direct-drive configurations to lower mechanical energy losses during continuous tracking routines.
For global industrial deployments, navigating regional certifications and import standards is vital. Jiangsu Manchen is fully aligned with global construction machinery and structural engineering frameworks.
All our slewing bearing designs and materials are certified under rigorous standards, conforming to high-load structural requirements for heavy solar operations. We collaborate with international third-party test entities (such as SGS, TUV, and BV) to deliver material certificates, hardness reports, and surface treatment certifications directly to your project’s documentation platform.
In addition, we have established long-term cooperative relationships with many well-known domestic enterprises. With stable quality and complete after-sales services, we have won wide recognition in the market. In the future, the company will continue to focus on technological upgrading in the transmission field, and strive to provide global customers with higher-quality and more cost-effective rotary transmission products and services.
