Technical DatasheetSpain is experiencing a rapid industrial transition. Regions such as Castilla y León, Aragon, and Galicia are shifting towards wind power generation, while major hubs like Catalonia and Valencia continue to expand their automotive manufacturing lines. This shift has changed the requirements for industrial gearboxes.
Traditional mineral gear oils struggle to cope with the dynamic shock loads of high-capacity wind turbine planetary gearboxes and the high cycle speeds of modern assembly robotics. Operating conditions require lubricants that provide extreme wear protection under variable loads, reduce micropitting on hardened gear teeth, and offer extended drain intervals to lower maintenance costs.
Providing specialized engineering solutions for Spain's primary commercial sectors.
Longhai Technology operates from a modern manufacturing base spanning 131 acres, with an annual production capacity of 200,000 tons. By integrating automated blending systems, we maintain precise batch-to-batch consistency for complex industrial formulations.
Our filling production lines are equipped with automated volumetric metering systems, guaranteeing a filling accuracy of 1‰ to 2‰. This automated system improves production efficiency by 20% to 35% compared to conventional operations, enabling fast order turnaround and dispatch times to major European ports.
We work with trusted shipping partners to coordinate logistics from Qingdao Port to Spanish hubs like Valencia and Barcelona, ensuring a reliable supply of key industrial lubricants.

Micropitting is a type of localized surface fatigue wear that commonly affects case-hardened gears in highly loaded applications, such as wind turbine gearboxes. It appears as microscopic cracks that can coalesce, causing surface flaking, tooth profile distortion, and eventual gear failure.
Our heavy-duty industrial gear oils are formulated with advanced sulfur-phosphorus extreme pressure (EP) chemistry that creates a resilient boundary lubricating film on gear surfaces. This formulation meets the FVA 54/7 test standard, maintaining a high level of protection (Load Stage ≥12) under variable speeds and heavy loads.
Selecting the appropriate base oil chemistry is critical for optimal industrial gearbox performance:
Spain's coastal industrial facilities and ports run in humid, salt-rich environments that accelerate rust and corrosion in gearboxes. Our lubricants incorporate specialized rust inhibitors designed to neutralize acidic degradation products.
Our formulations undergo testing against ASTM D665 (rust-preventing characteristics in the presence of synthetic sea water) and ASTM D130 (copper strip tarnish test). These additives help protect copper-alloy bushings, thrust washers, and steel gear teeth from corrosion, reducing system down-time.
Our products are engineered to align with global industrial standards and major OEM specifications, including:

Wind turbines operating in Spanish regions like Castilla y León experience highly variable wind loads and temperature fluctuations. This dynamic environment can thin the lubricating oil film, leading to surface fatigue and micropitting on gear teeth. Our industrial gear lubricants are formulated to exceed the FVA 54/7 test standard, maintaining a high micropitting protection rating (Load Stage ≥12). This helps extend gear life and reduces maintenance overheads in remote wind installations.
Our Zibo facility uses automated, computer-controlled blending machinery that precisely meters base fluids and additive packages. We verify raw materials before blending and test every finished batch in our laboratory. Each shipment is dispatched with a Certificate of Analysis (COA) containing viscosity index, flash point, pour point, water content, and copper corrosion ratings, ensuring consistent quality.
No. PAG (Polyalkylene Glycol) lubricants are chemically incompatible with mineral oils and PAO-based synthetics. Mixing them can lead to additive fallout, sludge formation, and a significant drop in viscosity, which can cause gear damage. When converting a gearbox to a PAG fluid, you must thoroughly flush the system to remove all traces of the previous lubricant.
For gearboxes operating in damp port and marine environments, we formulate our oils with premium rust inhibitors that adsorb onto metal surfaces. This protective layer repels moisture and prevents saline water from contacting the steel. Our marine-grade formulations pass the ASTM D665 (synthetic seawater rust test) and show low demulsibility, allowing water to separate quickly from the oil so it can be drained.
