High-rigidity, wind-resistant components designed to support Concentrated Solar Power (CSP) heliostats and heavy-duty industrial positioners.
As the global transition to sustainable energy accelerates, Concentrated Solar Power (CSP) has emerged as a cornerstone for utility-scale dispatchable green energy. Unlike conventional photovoltaic (PV) systems, CSP utilizes mirrors (heliostats or parabolic troughs) to focus sunlight onto a receiver, heating a fluid (often molten salt) that drives steam turbines to generate electricity even when the sun is not shining. To maximize optical efficiency, heliostats and parabolic collectors must track the sun’s trajectory with sub-milliradian precision throughout the day.
Information Gain Insight: The efficacy of a CSP plant hinges on the tracking system's ability to maintain optical targeting. A tracking error of just 0.1 degrees can lead to a 15% drop in heat generation efficiency. At the heart of this tracking precision is the slewing bearing, which must support heavy axial, radial, and overturning moment loads under harsh, wind-swept desert environments.
Jiangsu Manchen Transmission Technology Co., Ltd. is at the forefront of this technology, engineering state-of-the-art slewing bearing designs that directly translate into higher electricity yields for CSP operators. Our customized bearings provide structural rigidity, minimal backlash, and long-term durability to withstand high gust winds while preserving the precise orientation of solar concentrators.

The global concentrated solar power market is shifting towards hybridized and larger-scale utility projects. Developers are focusing heavily on the following core trends:
| Tracking Technology | Typical Bearing Type | Backlash Range | Primary Environmental Challenge | Key Advantage |
|---|---|---|---|---|
| Heliostat (Tower CSP) | Single-Row Cross-Roller / Ball | < 0.05° (Low Backlash) | Wind-induced vibration & dust ingress | Dual-axis tracking accuracy and high tilting stiffness |
| Parabolic Trough CSP | Large Diameter Gearless Ball / Roller | < 0.1° | Torsional load along the collector line | Heavy axial capacity to hold lengthy parabolic mirrors |
| Linear Fresnel | Lightweight L-Type / Gearless Ball | Standard | Cost constraint vs. service life | Easy maintenance, low friction torque |
Why EPCs and solar developers trust Manchen slewing bearings for critical power generation projects.
Cross-roller designs feature rollers arranged at 90-degree angles alternately, allowing a single bearing to absorb axial load, radial load, and tilting moments simultaneously. This maximizes structural efficiency in heavy winds.
Engineered with double-lip sealing systems (NBR or Polyurethane) that keep critical lubricants inside the rolling path while blocking ultra-fine sand and dust particles from causing abrasive raceway wear.
Precision induction hardening of the raceway surface (hardness range 55-62 HRC) combined with a resilient core prevents crack propagation and ensures the bearing handles high peak wind stowing stresses.
Every stage of production is executed in-house with precise quality inspections, maintaining high product integrity.
