Established in 2022 and situated in Huangtu Town, Jiangyin City, Jiangsu Province, Jiangsu Manchen Transmission Technology Co., Ltd. is a premier high-tech enterprise specializing in the design, research, development, and high-precision manufacturing of rotational transmission systems. Benefit from our strategic location which provides seamless global logistical access.
Leveraging state-of-the-art forging methodologies, advanced heat treatment processes, and computer-controlled precision machining, our factory provides heavy-duty, high-integrity, and extended-lifespan transmission solutions. Our products are widely deployed in Concentrated Solar Power (CSP) systems, photovoltaic solar tracking, heavy-duty machinery, medical instruments, intelligent storage systems, port automation, and industrial robotics.
We operate under a rigorous quality management paradigm, featuring fully traceable supply chain records from raw ingot certification down to final dimension auditing, ensuring compliance with strict international performance standards.
The technical connection between solar concentration accuracy and heat collection efficiency.
Concentrated Solar Power (CSP) facilities utilize vast heliostat fields to direct sunrays toward a central thermal receiver. A tracking error of just a fraction of a degree can throw the focal point wide, resulting in massive thermal energy collection drops. Our high-precision slewing drives minimize backlash, facilitating reliable concentration onto molten salt storage systems.
Thermal Energy Storage (TES) systems act as thermal batteries, capturing excess midday solar radiation to drive steam turbines at night. The storage capability is directly limited by the amount of heat gathered during peak hours. Our slewing solutions ensure consistent tracking under high wind loads, safeguarding continuous energy absorption.
Heliostats and parabolic troughs have expansive surface areas exposed to sudden, violent gusts. The internal gear structures and slewing rings must carry substantial overturning moments. Jiangsu Manchen's triple-row cylindrical roller designs offer the industry's highest axial and radial dynamic load rating capacity.
An inside look at our state-of-the-art precision machinery, processing facilities, and quality inspection floor.
How our localized industrial cluster in Jiangsu delivers unparalleled cost-to-performance metrics.
Located in China's industrial heartland, we source high-quality structural steel (such as 50Mn and 42CrMo) directly from leading domestic mills. The proximity to certified local heavy forgings facilities shortens processing lead times and significantly reduces raw material procurement costs, a saving we pass directly onto global engineering firms.
To withstand decades of outdoor solar tracking exposure, the raceways of our slewing bearings are subjected to precise induction hardening, reaching hardness values of 55-62HRC. Our automated thermal processing machinery ensures optimal hardening depth, keeping the bearing core tough while maximizing outer fatigue wear resistance.
Our factory floor is optimized for large-scale batches. CSP projects require thousands of tracking units built to identical dimensions. With our high-capacity production lines, we guarantee prompt delivery schedules without sacrificing micron-level tracking tolerances.
Solar thermal power stations are frequently situated in harsh desert environments with drastic temperature fluctuations, sandstorms, and humidity. Our components feature advanced seal profiles and specialized greases tested to maintain low torque resistance and high integrity under extreme operating temperatures (-40°C to +60°C).

How our slewing drives integrate into diverse renewable energy systems worldwide.
In solar tower designs, thousands of dual-axis tracking mirrors concentrate light onto a single thermal receiver. Our gearless or internal gear single-row slewing bearings offer high precision and zero axial drift, preventing target aberration and maximizing temperature gains.
Dual-Axis PrecisionParabolic troughs track the sun on a single axis to heat transfer fluid passing through receiver tubes. These long-span installations require slewing drives with exceptional torsional stiffness and backlash limiting capabilities to assure structural alignment along the entire receiver line.
High Torsional StiffnessUtilizing flat mirrors on long ground rows to reflect sunlight toward elevated receiver pipes, linear Fresnel systems present dense structural layouts. Our compact L-shaped and cross-roller slewing rings fit small footprints while ensuring robust overturning resistance.
Compact Spatial IntegrationFully compliant with international quality management systems to guarantee premium operational reliability.
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.
Expert technical insights regarding components, manufacturing standards, and installation requirements.
In CSP plants, slewing drives serve as the primary rotational driver for heliostats and parabolic trough collectors. They are responsible for matching the solar tracking algorithm with physical positioning, allowing mirrors to remain aligned with the sun during daily movement cycles. High-precision slewing drives minimize backlash, maximizing the percentage of solar energy focused on the thermal receiver, which in turn heats the molten salt stored in the Thermal Energy Storage (TES) facility.
CSP installations are typically deployed in regions with high solar irradiation, such as deserts. These areas experience extreme temperature gradients (ranging from freezing nights to blistering day temperatures), strong winds, and high levels of dust and grit. We use top-grade structural steels (50Mn or 42CrMo) with induction-hardened raceways (55-62HRC) and specialized temperature-tolerant seals. This configuration ensures our slewing rings maintain structural integrity, low torque values, and high protection against sand ingress over a 25-year design lifespan.
Our factory implements a comprehensive material traceability system. Each batch of raw steel receives a chemical composition inspection certificate. We carry out non-destructive testing (ultrasonic and magnetic particle checks) at various stages of forging and rough machining. Every manufacturing phase—from heat treatment to rolling path grinding—is logged in our quality system. This allows customers to inspect the full manufacturing history of their specific slewing drives, meeting strict global EPC standards.
Yes. We offer fully customized OEM & ODM design services. Depending on your system's design loads, target precision, wind resistance requirements, and mounting footprints, our engineering team can design specialized single-row ball, double-row ball, cross-roller, or three-row roller slewing bearings. We provide comprehensive technical blueprints, structural simulation reports, and sample testing support to ensure seamless physical and mechanical integration.
