Explore our premium grade single-row, double-row, cross-roller, and cylindrical roller bearings optimized for solar tracking accuracy and industrial gear mechanisms.
Linear Fresnel Reflector (LFR) technology has emerged as one of the most cost-effective and scalable approaches to Concentrated Solar Thermal (CST) and Direct Steam Generation (DSG). By utilizing long, narrow segments of flat or slightly curved mirrors that focus solar radiation onto an elevated receiver tube, LFR plants require dynamic tracking accuracy of the highest order.
At the center of this dynamic tracking performance are slewing bearings and rotary drive devices. These structural elements must bear immense static and dynamic loads—induced by severe desert winds, sandstorm erosion, and thermal cycles—while performing minute angular movements with sub-degree tracking tolerances (often < 0.1°). Any positioning backlash directly results in optical focus loss, drastically reducing steam yield and thermal output.
As a leading ODM Fresnel Solar Steam Generator component manufacturer & supplier, Jiangsu Manchen Transmission Technology Co., Ltd. supplies the precision heavy-duty bearings and horizontal/vertical slewing drives that serve as the mechanical backbone of these massive mirror arrays. By combining advanced materials, precise teeth profile cutting, and optimized heat treatment, we ensure your solar collectors run efficiently for 25+ years.
Examining the shifts in concentrated solar thermal power (CSP) and high-temperature industrial process heat (IPH).
The global energy landscape is undergoing a systemic transition toward deep decarbonization. While photovoltaic (PV) systems dominate power grids during peak sunlight, Concentrated Solar Thermal (CST) plants—particularly those utilizing Linear Fresnel Reflectors—provide high-temperature heat directly for industrial applications and thermal energy storage (TES). The modern trends shaping this industry include:
Traditional solar collectors utilized thermal oil as a heat transfer fluid (HTF). Modern utility installations are transitioning to Direct Steam Generation (DSG), where water is evaporated and superheated up to 400°C–500°C directly within the receiver tubes. This eliminates expensive heat exchangers and minimizes thermal degradation issues. Achieving these high temperatures requires tighter concentration ratios, placing extreme pressure on the accuracy of the solar tracking drives.
Over 74% of industrial energy demand is thermal, yet the majority is still generated by burning fossil fuels. Fresnel solar steam generators are increasingly being deployed at industrial sites for paper manufacturing, chemical processing, textile steaming, food processing, and district heating networks. These distributed utility plants require modular, compact tracking systems that can withstand varying local topography and architectural layouts.
"According to the International Energy Agency (IEA), solar thermal heat for industrial processes must grow tenfold by 2030 to keep pace with net-zero commitments. This demands high-durability, low-cost optical trackers built on standardized ODM slewing drives."
Fresnel solar plants are typically built in arid zones with high Direct Normal Irradiance (DNI), such as Northern Africa, the Middle East, Western China, and the Southwestern United States. These regions are subject to heavy dust storms and high wind shear. Sourcing slewing bearings with robust double-lip polyurethane seals and integrated wind-brake load capacities has become standard practice to prevent gearbox failures and ingress of abrasive sand particles.
A technical guide for Engineering, Procurement, and Construction (EPC) companies sourcing solar tracker bearings.
Sourcing engineers and product managers in the Concentrated Solar Thermal (CST) industry evaluate key technical and commercial metrics when choosing an ODM transmission partner. The selection criteria are highly rigorous, focusing on long-term reliability and total cost of ownership (TCO):
Tailored engineering solutions for utilities, district heating, and multi-megawatt solar steam fields.
At Jiangsu Manchen Transmission Technology Co., Ltd., we develop targeted solutions to match the structural architecture of your solar steam projects:
For large-scale, grid-tied solar thermal plants, we supply heavy-duty three-row cylindrical roller and double-row equal-diameter ball slewing bearings that support massive mirror frames spanning up to 100 meters per tracking loop, ensuring optimal system uptime.
Modular designs that require rapid installation and zero-maintenance operation. Our gearless single-row ball bearings and pre-lubricated horizontal rotary drives are optimized for rooftop or ground-mount industrial steam installations.
In Enhanced Oil Recovery (EOR) applications, solar steam is injected into oil reservoirs to lower viscosity. These harsh desert oilfield environments demand our sealed, high-protection cross-roller rotary drives that prevent particulate damage.
Our complete in-house manufacturing process ensures full control over raw materials, precision machining, induction hardening, and product packaging.
Our ISO-certified manufacturing facility operates with complete traceability, meeting the stringent international standards of global energy projects.
Jiangsu Manchen Transmission Technology Co., Ltd. believes that quality is the cornerstone of sustainable growth. Our factory in Huangtu Town, Jiangyin City, Jiangsu Province is equipped with advanced testing machines, including coordinate measuring machines (CMM), ultrasonic flaw detectors, magnetic particle testers, and hardness testing equipment. The products are systematically tracked from metallurgical verification at the raw material stage to the geometric validation prior to dispatch.

How we are developing the next generation of solar tracker slewing drives and intelligent bearings.
As Fresnel solar power plants continue to scale in capacity, the requirements for drive systems are evolving. Jiangsu Manchen is actively investing in three primary R&D focus areas to support this transition:
Developing customized bronze and synthetic matrix composite cages that eliminate manual greasing cycles. This reduces operating expenditures (OPEX) in remote desert installations where labor access is limited.
Integrating vibration, temperature, and wear-monitoring sensors inside the slewing bearing raceways. These sensors feed real-time structural health data to the plant SCADA system to trigger predictive maintenance.
Developing envelope worm gears that contact more teeth simultaneously. This results in significantly higher torque handling, lower backlash, and superior resistance to wind gusts.
