Explore our elite range of lubricants designed for high-performance industrial gear systems, heavy-duty gearboxes, and turbine assemblies.
A high-tech enterprise integrating R&D, production, and sales since 2009.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years building a highly integrated industrial lubricants supply system. As a reliable, high-tier lubricant manufacturer, we operate our own domestic brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series. The quality of our product range is backed by the comprehensive liability insurance of the PICC (People's Insurance Company of China).
Our expansive inventory caters to global industrial machinery and automotive sectors. It spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized engineering machinery fluid, natural gas engine oil, fully synthetic fluids, automotive urea solutions, antifreeze, automatic transmission oil, and specialized motorcycle lubricants.
Longhai Technology operates under rigorous international operational frameworks. We hold certifications for ISO-9001-2015 (Quality Management), ISO-14001 (Environmental Management), and ISO-18001 (Health and Safety Management). Furthermore, our automatic transmission fluids have achieved official Mercedes-Benz Certification, reflecting our technical capabilities and commitment to producing highly stable lubricants that perform under severe temperatures and pressures.
Understanding base oil chemistry, oxidation stability, and shear performance in modern compressor networks.
Industrial rotary screw, reciprocating piston, and dynamic centrifugal air compressors run under extreme thermal stresses. To sustain operations without varnish or carbon buildup, selecting a high-performance compressor oil is critical. At Longhai, we engineer lubricants that provide thermal durability, moisture demulsibility, and oxidative stability.
Our synthetic formulations utilize custom-refined base stocks paired with modern ashless anti-wear chemistry. This combination inhibits varnish formation, ensuring clean internal valves and lower particulate levels across extended drain intervals.
Formulated to deliver up to 8,000+ hours of continuous operational service in rotary screw systems, reducing mechanical wear, lessening maintenance downtime, and lowering total cost of ownership (TCO).
High moisture levels in compressed air systems can lead to sludge formation. Our oils feature strong water-separation metrics, allowing condensed water to be drained without washing out essential additives.
In response to evolving environmental standards, Longhai's engineering teams are refining next-generation biodegradable PAG (Polyalkylene Glycol) and POE (Polyol Ester) synthetic formulations. These eco-focused solutions provide high thermal stability and shear protection while complying with global environmental mandates. Our roadmap also includes developing low-volatility lubricants designed for high-vacuum, high-pressure environments, reducing oil carryover into downstream lines.
Different industrial fields require tailored lubrication approaches:
How our automated facility in Zibo delivers batch-to-batch consistency and supply chain stability.
Our production base spans 131 acres with an annual capacity of 200,000 tons. It features automated batching setups and a dedicated QC laboratory. By deploying PLC-controlled blending systems, we maintain precise temperature curves and additive ratios, reducing batch variance.
Our bottling hall uses volumetric metering fillers to secure a filling accuracy of 1‰-2‰. This setup reduces product loss, decreases cycle times by 20% to 35%, and helps guarantee reliable delivery windows for high-volume export orders.
Customized fluid engineering for global brands, private labels, and equipment manufacturers.
We design synthetic and semi-synthetic lubricants tailored to specific climates, load metrics, and viscosity grades (ISO VG 32, 46, 68, 100, 150) that meet API, ACEA, and DIN standards.
Our facility supports both small run tests and bulk container production. We offer variable packaging shapes, including 4L canisters, 18L pails, and 200L drums.
Every customized formulation undergoes ASTM-standard laboratory validation. We issue Certificates of Analysis (COA) and material safety documents to support your regulatory compliance.
We provide structural layout support for private labels, including weather-resistant print labels and custom packaging designs, helping you build a professional brand image.
