Premium high-performance synthetic and heavy-duty formulations engineered to withstand intense thermal and mechanical shear.
The stability of transport networks, heavy-duty mining systems, maritime shipping vessels, and industrial machinery depends on precise fluid mechanics. Among these components, steering gears and directional mechanisms are highly vulnerable. Utilizing high-grade wholesale steering gear oil is not merely a maintenance decision; it is a critical strategy to prevent system wear and extend equipment lifespans.
Modern commercial vehicles and heavy machinery operate under challenging conditions. In areas with high dust levels, extreme cold, or intense heat, steering gear systems face severe structural stress. High-quality steering gear lubricants protect steering pumps, control valves, and gear teeth against micro-pitting, hydraulic cavitation, and oxidation.
As international trade grows and supply chains shift, industrial operators require lubrication partners who deliver excellent formulations and comply with strict environmental and import regulations. Shandong Longhai Lubrication Technology Development Co., Ltd. offers customized fluid designs, large-scale production, and reliable logistics support for global markets.
High operating temperatures accelerate oil aging and acid formation. Our steering gear oils use Group II/III hydrocracked base oils and high-purity synthetic esters to resist oxidation, ensuring long fluid life and minimal sludge build-up.
Steering systems generate high shear forces in narrow gear meshes. Our lubricants contain high-molecular-weight Viscosity Index Improvers (VII) that resist mechanical breakdown, maintaining reliable viscosity in all conditions.
Under heavy mechanical shock loads, fluid film can fail. We incorporate zinc dialkyldithiophosphate (ZDDP) and advanced phosphorus-sulfur compounds to create a protective boundary layer that prevents scuffing and micro-pitting.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. Deeply involved in the lubricant industry for over 15 years, the company has built a complete industrial chain system dedicated to providing high-quality lubrication solutions for global industrial and transportation fields.
As a trusted manufacturer in the industry, Longhai Technology owns the brand "Century Longhai" alongside the international strategic cooperation brand, British "A Ba" series. Our comprehensive product range covers diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, automatic transmission oil, and more.
To provide peace of mind to our worldwide client base, our entire brand line is insured by PICC China People's Insurance Company, guaranteeing quality assurance and global reliability.
Innovation drives our development. Longhai Technology allocates more than 5% of its annual revenue to R&D. We maintain strategic partnerships with universities and research institutions to develop advanced lubrication technologies. Our production base spans 131 acres, with an annual capacity of 200,000 tons.
Our facility features advanced blending and fully automatic filling equipment. The filling lines use volumetric metering principles, suitable for processing various lubricants with a metering accuracy within 1‰ to 2‰. This system increases filling speeds by 20% to 35%, ensuring fast delivery and consistent quality.
Longhai Technology has established a distribution network across China, serving 139 cities in 29 provinces, autonomous regions, and municipalities. Our expanding export operations supply reliable lubrication products to industrial and transport businesses worldwide.
Product safety and regulatory compliance are essential for lubricants. Our operations are certified under ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, and ISO 45001 / OHSAS 18001 for occupational health and safety.
Additionally, our automatic transmission lubricants have received formal Mercedes-Benz certification. This confirmation underpins our product quality and demonstrates that our fluids can perform under demanding operational conditions.
We follow strict quality guidelines and implement standardized testing and inspection procedures. This guarantees that each batch of steering gear fluid, diesel engine oil, and industrial lubricant meets global performance benchmarks before shipping.
We support global brands with custom formulated lubricants, flexible packaging options, and full laboratory validation.
We design fully synthetic and semi-synthetic lubricant formulations to match specific machinery requirements, regional climates, and target market positioning. All custom products are blended to comply with international standards such as API, ACEA, and relevant ISO grades.
Whether you need a high-viscosity steering gear oil for warm climates, a synthetic fluid for sub-zero environments, or heavy-duty industrial gear lubricants, our R&D team works closely with you to validate performance before full production.
Exporting lubricants requires thorough documentation and compliance. Longhai Technology ensures all international orders ship with complete Material Safety Data Sheets (MSDS), custom declaration files, and certificate compliance documents.
Our logistics division works with major shipping lines to coordinate bulk freight, flexitank deliveries, and smaller container options. This supports timely delivery to key markets in Southeast Asia, the Middle East, Central Asia, Eastern Europe, and South America.
Temperature fluctuations impact lubricant viscosity. For arctic climates, we develop synthetic steering gear oils with low pour points (down to -45°C) to prevent steering hesitation and pump damage.
For tropical and high-heat regions, we formulate fluids with high shear stability and stable viscosity indices. This prevents thinning at high temperatures, ensuring reliable steering gear performance under heavy loads.
We are developing bio-degradable base oils to support sustainable forestry, agriculture, and marine operations. These fluids offer quick biodegradation in environmental contact while maintaining high performance.
Electric Hydraulic Power Steering (EHPS) systems require fluids with specific electrical resistance and dielectric properties. Our R&D team is refining specialized fluids to optimize thermal regulation in electric pumps.
By utilizing high-purity synthetic hydrocarbons and antioxidant additive chemistry, we aim to extend fluid service intervals. This helps fleet operators reduce maintenance frequency and total lifecycle costs.
