Explore our elite selection of industrial transmission and engine fluids optimizing high-precision machinery.
The Swiss industrial framework is synonymous with ultimate precision, reliability, and stringent environmental ethics. Operating within highly specialized sectors—such as high-end watchmaking tool assembly, Swiss-type CNC precision turning machinery, advanced railway networks traversing alpine corridors, and subterranean tunnel boring operations—demands nothing short of extreme performance from hydraulic transmission media.
In the Swiss market, hydraulic transmission oils are no longer viewed as mere operational consumables. Instead, they are classified as critical system components that determine the life-cycle costs (LCC) and total cost of ownership (TCO) of highly valued machinery. As the Swiss federal guidelines push towards carbon-neutral footprints and eco-friendly raw materials, suppliers must achieve a delicate balance: delivering exceptional shear stability and anti-wear protection while aligning with the strict Swiss VOC incentive tax exemptions and environmental compliance protocols.
Consequently, global enterprises seeking to export to Switzerland are transitioning toward Group III synthetic base stocks and eco-compatible, high-viscosity-index formulations. At Shandong Longhai Lubrication Technology, we tailor our high-performance lubricants to address these exact requirements, ensuring that alpine temperature variances do not compromise system pressures or component integrity.
Formulated to preserve structural viscosity indexes under rapid temperature swings from -30°C in Swiss winter construction zones to +80°C in heavy-duty machinery gearboxes.
Engineered to align with progressive Swiss eco-standards, reducing zinc emissions and supporting biodegradability indicators without sacrificing lubricating film strength.
Ensures zero-shear breakdown under continuous extreme pressures of up to 350 bar, safeguarding mechanical pumps from cavitation and micro-pitting.
Shandong Longhai's scale and capabilities back our performance guarantee across key global markets, including Europe.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a state-recognized high-tech enterprise integrating pioneering research, large-scale production, and global supply configurations. Over 15 years, we have built a fully integrated supply chain system optimized to deliver premium lubrication solutions to industrial and heavy transportation fields worldwide.
Operating under our proprietary brand "Century Longhai" alongside our international strategic partnership brand, the British "A Ba" series, our portfolio spans heavy-duty diesel engine oil, high-efficiency gasoline engine oil, industrial gear fluids, hydraulic transmission fluids, anti-wear hydraulic oil, and engineering machinery specialty lubricants. Crucially, our absolute commitment to reliability is demonstrated by our product liability policies, which are insured globally by the PICC (People's Insurance Company of China), providing our European partners with an airtight safety net.
Our infrastructure covers 131 acres with an annual production throughput of 200,000 tons. Equipped with fully automated metering filling systems, we guarantee high-precision volumetric packaging (accuracies of 1‰-2‰) while boosting processing speeds by 20% to 35%. This high-capacity capability guarantees reliable batch uniformity and fast delivery times to the European continent, especially Switzerland.
Why modern Swiss hydraulic systems require advanced formulation architectures for long-term stability.
In high-pressure hydraulic pumps (vane, piston, and gear variants), fluids are subjected to immense mechanical shear rates. Standard hydraulic oils experience long-chain polymer breakdown under these conditions, causing permanent viscosity loss. Longhai's specialized hydraulic fluids integrate shear-stable Viscosity Index Improvers (VII) that resist mechanical stress. This ensures that the fluid maintains a stable, protective hydrodynamic lubricating film even at operational limits, keeping volumetric efficiency above 95% and protecting internal components from wear.
Furthermore, Switzerland's high-humidity environments require hydraulic oils with excellent hydrolytic stability. If water enters a hydraulic system, it can trigger oil hydrolysis, causing acid formation and copper catalyst reactions. Our formulations are balanced with advanced demulsibility additives that rapidly separate water from the oil, allowing for easy drainage and preventing metal rust and chemical corrosion.
Precision machinery uses ultra-fine filtration systems (frequently 3-to-5-micron ratings) to safeguard sensitive proportional valves. Incompatible hydraulic fluids can form sludge, varnish, or gelatinous by-products that block these filters. This triggers system pressure drops and forces frequent maintenance shutdowns. Longhai's low-zinc and ashless hydraulic oils are formulated to maintain excellent filterability in both dry and wet conditions, ensuring uninterrupted flow and minimal pressure drops across fine filter membranes.
Additionally, rapid air release and low foaming characteristics are critical to preventing fluid compressibility and pump cavitation. Our fluids feature advanced air-release technology that detrains dispersed air bubbles within minutes, ensuring instant hydraulic system response and avoiding localized hotspots caused by micro-diesel effects inside the pump chambers.
High thermal stress accelerates oil oxidation, leading to varnish deposits on hot surfaces and increased viscosity. Our Group II/III base oil blending process provides naturally high thermal stability. Augmented by synergistic antioxidant systems, our transmission oils successfully delay the onset of oxidation. The results are clear: extended drain intervals that are two to three times longer than standard mineral oils, reduced downtime, and lower disposal costs—aligning directly with Switzerland's environmental waste reduction targets.
For Swiss distributors and machinery manufacturers, regulatory compliance is non-negotiable. Shandong Longhai Lubrication Technology operates under a comprehensive quality and environmental framework, certified by ISO 9001:2015 Quality Management, ISO 14001:2015 Environmental Management, and ISO 45001:2018 Occupational Health & Safety Management Systems.
Additionally, our automatic transmission oil formulations carry official Mercedes-Benz approvals, testifying to our ability to meet the stringent standards of European automotive OEMs. Every batch undergoes rigorous quality control testing in our precision labs to guarantee consistent viscosity, wear scar diameter (under four-ball testing), and rust prevention performance before shipment.
