Explore our high-performance synthetic motor oils, heavy-duty engine lubricants, and specialized hydraulic transmissions designed to meet rigorous international standards.
How state-of-the-art additives, thermal stability, and shear control define the next generation of industrial fluid power lubrication.
Modern industrial gearboxes and hydraulic systems subject fluids to severe mechanical shear. Our formulations utilize highly stable viscosity index improvers to ensure the protective oil film thickness remains uninterrupted even under extreme boundary lubrication pressures.
High temperatures speed up oil degradation, producing sludge and varnish. Our Premium Synthetic Gear and Hydraulic Oils are fortified with primary and secondary antioxidants to extend oil service intervals by up to 300% compared to conventional fluids.
Specifically designed for high-pressure piston, vane, and gear pumps. By minimizing metal-to-metal contact through chemical adsorption, our anti-wear packages substantially reduce internal component wear and prolong critical hydraulic pump service life.
Leveraging state-of-the-art infrastructure, advanced quality control systems, and strategic logistics in Zibo, Shandong.
Established in 2009, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. For over 15 years, our facility in Zibo, Shandong has delivered superior industrial and automotive fluids across the globe. Our factory features:
Delivering tailored lubricants aligned with API, ACEA, and specific international heavy machinery standards.
Helping international brands build a reliable market presence with robust product formulations.
Fully synthetic and semi-synthetic products optimized for extreme operating temperatures.
Supporting small pilot runs as well as high-volume runs with custom fill sizing.
Products tested and approved to meet ISO 9001, 14001, and OEM standards.
End-to-end design, packaging development, and professional technical documentation support.
Our commitment to reliable performance under extreme conditions is backed by strict compliance audits and international certifications.
Our production facilities operate in full compliance with global health, safety, and environmental regulations. These operational guidelines protect raw material traceability and chemical purity:
Addressing targeted engineering challenges across key industrial sectors and extreme operating environments.
Excavators, loaders, and mobile drilling rigs operate in environments with high airborne dust and moisture. Our specialized anti-wear hydraulic oil features superior hydrolytic stability and particulate filtration to shield close-tolerance servo valves from abrasive wear.
Industrial gearboxes encounter high shock loads. Formulated with ashless extreme pressure (EP) chemistry, our Heavy-Duty Gear Oils protect high-load gears from micropitting, extending gear and bearing life in critical systems.
High-humidity environments demand robust rust prevention. Our marine-grade hydraulic transmission fluids form a dense chemical barrier that isolates metal surfaces from saltwater, preventing rust and ensuring reliable deck machinery operation.
Our five-step framework coordinates design, production, and verification to deliver quality fluids to global distribution hubs.

Analyzing technical evolutions and market dynamics that are shaping modern lubrication standards.
Industrial sectors are adopting low-viscosity fluids to improve energy efficiency. Thinner lubricants minimize internal fluid friction, lowering energy consumption. Advanced shear-stable additives ensure these fluids maintain protective oil films under high pressure.
Environmental regulations are driving the adoption of biodegradable fluids in agriculture, marine operations, and forestry. Synthetic ester formulations balance low toxicity and rapid biodegradation with high-temperature oxidation protection.
