BX-306/E-WY High-Temperature Molybdenum Disulfide Grease Baoxing High-Temperature Grease One-Step Solution


With the large-scale deployment of domestic photovoltaic power stations, complex operating scenarios such as mountainous areas, water surfaces, and deserts have driven a sharp surge in demand for PV cleaning robots, which have become core essential equipment to reduce costs and improve efficiency in PV operation and maintenance.

As the core power component of photovoltaic cleaning robots, the planetary reduction gearbox operates long-term outdoors under extremely harsh conditions: ultra-wide temperature fluctuations from -25℃ to 250℃ and heavy-duty reciprocating operation. This brings prominent operational challenges and severe lubrication pain points. Ordinary greases show poor environmental adaptability, drying out at high temperatures and thickening severely at low temperatures, leading to rapid lubrication failure. Heavy-load gear meshing generates loud operating noise and severe abrasive wear, greatly reducing overall equipment stability. 

Most conventional lubricants lack long-lasting durability and cannot pass strict 500-hour endurance tests. They easily drain and dry up quickly, raising frequent maintenance costs. Meanwhile, all accessory materials must comply with RoHS environmental standards, further raising the technical threshold for qualified lubricant selection.


Targeting all high-temperature and heavy-load lubrication difficulties of planetary gearboxes in PV cleaning robots, Baoxing provides a customized professional solution: 

BX-306/E-WY High-Temperature Molybdenum Disulfide Grease. Formulated with premium synthetic base oil and solid molybdenum disulfide additives, it delivers stable performance across an ultra-wide temperature range of -40℃ to 300℃, fully meeting the extreme outdoor working requirements of -25℃ to 250℃ for PV equipment.

 Featuring excellent extreme-pressure resistance and outstanding anti-wear performance, it effectively reduces gear meshing friction, suppresses vibration, and realizes significant noise reduction during continuous operation. With strong oil retention and anti-drying properties, the grease maintains stable lubricating performance even after rigorous 500-hour long-life testing, reliably protecting gearbox components for extended service cycles. In addition, it fully complies with RoHS and REACH environmental certifications with zero compliance risks.


With 20 years of deep expertise in domestic specialty lubrication manufacturing, Baoxing focuses on tailor-made industrial lubrication solutions for the manufacturing industry. BX-306/E-WY high-temperature molybdenum disulfide grease matches the performance of international high-end lubricant brands and serves as a perfect direct replacement for imported Molykote BR2 high-temperature lubricants. We provide one-stop exclusive technical support for PV robot manufacturers, including independent formula research and development, on-site working condition customization, free sample testing, and full-cycle professional technical docking services.


Up to now, Baoxing has served more than 30,000 enterprise customers and established long-term in-depth cooperation with leading robot manufacturers such as Suzhou Xiaoqiang. With reliable product quality and professional on-site service capabilities, we effectively help PV cleaning equipment reduce overall operation and maintenance costs, extend the full-service life of machinery, and continuously empower the high-quality development of the intelligent photovoltaic cleaning industry.
