Engineered for extreme pressure environments, high thermal stability, and maximum component life cycle.
Modern industrial gearboxes function under unprecedented levels of mechanical stress, torque transients, and thermal loads. To prevent surface failures like micropitting, adhesive scuffing, and fatigue-induced spalling, specialized lubricant formulation is paramount. Shandong Longhai Lubrication Technology leads the industry by deploying advanced additive chemistries—including sulfur-phosphorus extreme pressure (EP) agents, modern shear-stable polymers, and oxidative inhibitors—ensuring high micro-wear defense across heavy industrial gear drives.
Our formulation principles strictly align with the critical demands of international standards, guaranteeing performance margins that exceed traditional mineral products:
Leveraging high-capacity automated blending lines and structural supply chain efficiencies to deliver premium industrial oils.
Operating from our expansive 131-acre high-tech production base in Zibo, Shandong, we utilize advanced automated blending facilities designed to ensure extreme consistency. With an annual production capacity of 200,000 tons, our factory is fully structured to support massive global demand without supply-chain bottlenecks.
Our filling operations utilize high-accuracy volumetric and metering flow control systems, achieving filling tolerance limits between 1‰ and 2‰. This precision-driven automated workflow boosts filling efficiency by 20% to 35% over legacy manual methods. This directly translates to reduced lead times, guaranteed packaging seal integrity, and highly competitive unit costs for bulk wholesale purchasers.
By sourcing raw materials directly from global primary base oil refiners and chemical additive manufacturers, we offer localized stability and cost resilience against international shipping volatility.
Addressing the specific engineering needs and risk mitigation requirements of global procurement directors.
For industrial procurement teams managing large fleets or heavy machinery sites, lubricant acquisition is more than a purchase order; it's a preventative maintenance strategy. High-performance gearbox lubricants lower power consumption by reducing internal fluid friction within gear meshes. This reduction in operating temperatures translates to lower energy bills and extended seal lifetimes, preventing unexpected shutdowns.
We work closely with global procurement departments to manage critical supply considerations:
Comprehensive local technical assistance, environmental compliance, and international system certifications.
To operate reliably in international markets, compliance is key. Shandong Longhai Lubrication has established a comprehensive quality and environmental safety system certified under ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health & Safety Management).
Additionally, our high-performance lubricants have passed certifications such as Mercedes-Benz (MB-Approval) for automotive transmission technologies. This level of verification confirms that our products remain stable under extreme pressure conditions and heavy work environments.
To protect global buyers, our formulations are insured by the People's Insurance Company of China (PICC), offering an extra layer of product quality liability security. In key regional markets, our distributors provide localized technical assistance, oil condition monitoring services, and used-oil analysis support to maximize operational reliability.
Custom-blended gear and engine lubricants designed for your brand's technical specifications and target market.
Every industrial market has unique operating requirements based on regional climate variations, local emissions regulations, and operational equipment types. Shandong Longhai provides a full suite of OEM/ODM custom development options. We support partners from packaging design and branding through custom formulation engineering.
Developing fully synthetic (PAO, Ester) and semi-synthetic products optimized for extreme operating temperatures or high loading rates.
Supporting both localized small-batch pilot trials and high-volume runs for global distribution networks.
Ensuring compliance with ISO 9001 and industry approvals. We provide complete analysis certificates (COA) for all deliveries.
Providing custom package designs, label printing, regulatory compliance datasheets (SDS), and technical documents.

Delivering high mechanical stability and protection across diverse industrial and automotive systems.
Industrial lubricants must protect equipment operating under variable, demanding conditions. Our formulations are designed to maintain protection across a wide range of real-world application scenarios:
Addressing the common technical inquiries and operational concerns of plant engineers and procurement managers.
The distinction is primarily determined by their load-carrying capacity and resistance to mechanical wear. L-CKC medium-load industrial gear oil is formulated for standard spur, helical, and bevel gear configurations operating under medium pressures. L-CKD heavy-duty gear oil is engineered with advanced extreme pressure (EP) chemistry to protect gear teeth under extreme loads and shock loading. L-CKD offers superior micropitting protection, thermal stability, and oxidation control, making it suitable for continuous-duty, high-load machinery.
While synthetic gear oils (typically PAO or synthetic esters) have a higher initial purchase cost, they offer significantly lower overall operating costs (TCO). Synthetic lubricants have a higher viscosity index (VI), providing better oil film thickness at high operating temperatures and lower fluid friction at start-up. This reduces wear, extends equipment life, and can improve energy efficiency by 1% to 3%. Furthermore, synthetics have higher oxidation resistance, extending oil change intervals by 3 to 5 times compared to mineral oils, which reduces maintenance labor and disposal costs.
Yes. Our in-house research laboratory and precision blending plant allow us to formulate custom lubricants that meet ISO VG, AGMA, or SAE viscosity requirements. Whether you require specific shear stability, low-temperature pour points, or tailored extreme pressure performance, our engineering team can formulate, test, and manufacture products to meet your specific technical requirements and national standards.
We use a multi-step quality control system certified to ISO 9001 standards. Every raw base oil and additive shipment is tested before unloading. Our automated blending systems monitor temperature, weight, and mixing times in real-time. Post-blending, every batch is tested in our laboratory for viscosity at 40°C and 100°C, flash point, pour point, water content, and elemental breakdown via spectroscopy. Retained samples of all shipped batches are archived for product traceability.
We provide full export support, including GHS-compliant Safety Data Sheets (SDS), certificates of analysis (COA), customs declarations, and bill of lading documents. Our proximity to major shipping hubs in Shandong allows us to offer flexible logistics options, including ocean freight in dry containers, flexitanks, and ISO tank containers, ensuring competitive rates and reliable delivery times.
Standard lead times for existing private label designs are generally 15 to 20 days. For custom formulation development or new packaging designs, lead times typically range from 30 to 45 days. This allows for laboratory testing, packaging approvals, print proofing, and full production scheduling.
Advanced engine protection, high thermal stability, and low viscosity shear degradation.
