Henan San Kuang Machinery Technology Co., Ltd., a professional manufacturer established in 2022 with a factory area of 10,000–30,000 square meters, proudly presents our slewing bearing for solar tracking systems. With a diameter of 1.2 meters and a positioning accuracy of 0.5°, this bearing is engineered to optimize the efficiency of solar trackers by ensuring precise alignment with the sun's trajectory. Our product combines robust construction with high reliability, making it an ideal choice for both utility-scale photovoltaic plants and concentrated solar power (CSP) installations.
Our slewing bearing is designed to withstand harsh environmental conditions, including wind loads, temperature fluctuations, and UV exposure, while maintaining smooth rotation and minimal maintenance. Backed by our company's ISO9001, ISO14000, and OHSAS18001 certifications, we guarantee consistent quality and traceability from raw material to final assembly. With an annual export value of US$2.5–5 million and a team of 51–100 skilled employees, we are committed to delivering reliable solutions for the global renewable energy market.
Key Features & Technical Specifications
- High positioning accuracy: 0.5° ensures optimal solar tracking, increasing energy yield by up to 15% compared to fixed-tilt systems.
- Robust load capacity: Engineered to support axial, radial, and moment loads typical of dual-axis and single-axis trackers.
- Durable materials: Made from high-quality alloy steel (e.g., 42CrMo4) with heat treatment for hardness and wear resistance.
- Customizable configurations: Available with internal or external gear teeth, single or double row ball/roller designs, and various sealing options.
- Corrosion protection: Surface treatment includes zinc plating, phosphating, or special painting to withstand outdoor exposure.
- Low maintenance: Pre-lubricated with long-life grease; optional automatic lubrication system.
- Easy installation: Precision-machined mounting holes and smooth raceways for simple integration with tracker structures.
