Zhongtian Petrochemical launches dedicated industrial robot grease to support reducers, joints, and smart manufacturing applications.
The Ignored “Joint Blood”: Zhongtian Petrochemical Brings Chinese Robots Dedicated Domestic Grease
In the era of intelligent manufacturing, industrial robots are everywhere in factories—working tirelessly 24 hours a day, reaching precision up to one-tenth of a hair strand, and delivering 3–5 times the efficiency of human labor. They quietly power production lines across automobiles, 3C electronics, semiconductors, new energy, and countless other industries.
Many people think robots are all about chips, algorithms, and reducers. But few know this: robot lifespan depends 60% on lubrication. This small tube of grease is the robot’s joint blood.
First, Understand the Basics
What Exactly Is an Industrial Robot?
Simply put, an industrial robot is a programmable, multi-joint, high-precision mechanical arm that can handle welding, handling, assembly, inspection, palletizing, and other repetitive heavy tasks. It is the “super employee” of modern factories.
Its three core components are:
- Controller: the robot’s “brain,” issuing commands
- Servo motor: the robot’s “heart,” providing power
- Reducer: the robot’s “joint,” controlling speed and torque
The reducer accounts for 30%–35% of total robot cost and is the most technically demanding component. Whether a reducer performs well and lasts long depends largely on the lubricating grease.
The reality is harsh:
German robots can last nearly 10 years, while many domestic robots suffer “joint failure” after about 3 years. The gap is often not in steel, not in machining, but in that overlooked tube of lubricating grease.
China’s industrial robot inventory has exceeded 1.5 million units, making it the world’s largest market for 10 consecutive years (source: China Robot Industry Alliance). But every year, losses caused by reducer failure, downtime, and scrapping due to improper lubrication reach tens of billions of yuan (source: China Machinery Industry Federation).
Even more brutally, 60% of robot short lifespan cases are caused by improper lubrication.
Market Landscape
International Giants Dominate the High-End Market
Industrial robot dedicated grease may seem inconspicuous, but it is actually an invisible global technology war. For a long time, the global market has been firmly controlled by Japan, Germany, and the United States, forming a difficult-to-break “iron triangle”:
Japan Kyodo Yushi: a globally recognized enterprise in the field of industrial robot dedicated grease. It has cooperated with robot giants such as FANUC and Yaskawa for more than 30 years. It has significant advantages in operating data accumulation, patent layout, and formulation technology, and has long dominated the global high-end market, making it difficult for domestic companies to match.
German and American brands: strong in niche fields such as extreme-pressure anti-wear and high-temperature stability.
Their “moats” are extremely high:
- Material barriers: special thickeners and low-volatility formulations, with evaporation loss as low as below 1%
- Data barriers: decades of real-machine operation data forming a “know-how” black box
- Standards barriers: leading international robot lubrication standards such as ISO, while we have long been following behind
For a long time, domestic high-end robot grease has relied heavily on imports. Hard to buy, expensive to buy, slow to supply, and poor in compatibility—these have been hidden bottlenecks.
Zhongtian Petrochemical Breaks Through
Overcoming Technical Bottlenecks and Breaking the Monopoly
Facing a 30-year foreign technology wall, the Zhongtian Petrochemical R&D team has spent years on focused research, carried out thousands of experiments and multiple rounds of project breakthroughs, and successively solved five core technical bottlenecks restricting domestic grease development. Through independent R&D and technological upgrading, Zhongtian Petrochemical’s related technologies have all been independently developed, with complete independent intellectual property rights and no infringement of any third-party patents.
Specific breakthroughs include:
- Understanding the “anatomy” of precision reducers to achieve accurate grease delivery and eliminate dry friction
- Solving the ultra-wide temperature range of -40°C to 150°C, remaining stable in severe cold and non-oxidizing at high temperatures
- Balancing extreme-pressure anti-wear with low-friction quiet operation, so it can carry heavy loads while staying precise and quiet
- Achieving long life plus high cleanliness, without oil separation, volatilization, or cavity contamination
- Completing machine-level compatibility verification, so what works in the lab also stays stable in actual installation
From “following” to “running side by side,” Zhongtian Petrochemical has officially launched its dual-star series of industrial robot dedicated lubricating grease. Its performance benchmarks top international brands and enables domestic high-end substitution.
New Product Interpretation
RV Type: The “Life-Saving Tool” for Heavy-Duty Joints
Who is it for?
Automotive welding, casting handling, heavy palletizing, and other scenarios involving hard work and strong impact.
Three major strengths:
- Penetrates like mercury: NLGI 00 semi-fluid grade, automatically fills gear gaps for 360° lubrication
- Does not back down under pressure: strong extreme-pressure anti-wear performance, smaller wear scar and stronger load-bearing capacity
- All-weather, north-south compatible: does not harden at -40°C and does not oxidize at 150°C, suitable for cold storage and steel mills
HG Type: The “Silent Guardian” for Precision Transmission
Who is it for?
3C electronics, semiconductors, medical robots, and other scenarios requiring precision, cleanliness, and quiet operation.
Three major strengths:
- Almost no “sweating”: extremely low evaporation loss, does not dry out or carbonize, safe for cleanroom and vacuum environments
- Runs extremely quietly: special anti-friction formula, significantly reduces noise, almost “invisible” in precision workshops
- Maintains hair-thin precision: anti-micro-motion wear, long-term retention of ±0.01 mm repeat positioning accuracy, zero-error performance for chip assembly and precision operations
Application Scenarios
From Automobile Manufacturing to Future Factories
With the full promotion of the “Robot+” initiative, robot density in China’s manufacturing industry continues to double. Robot lubricating grease is entering a golden growth period: from 2025 to 2030, the market is expected to grow at a compound annual rate of over 15%, and the share of high-end dedicated grease is expected to rise from 30% to 60% (source: Prospective Industry Research Institute).
Zhongtian Petrochemical robot dedicated grease now covers all-scenario intelligent manufacturing:
Core battlefields: automobile manufacturing, 3C electronics, metal processing, food and beverage
Emerging growth areas: new energy lithium battery / photovoltaic, medical robots, aerospace, humanoid robots
In the future, smart lubrication, bio-based eco-friendly grease, ultra-long relubrication technology, and multi-physical-field adaptation will continue to advance.
Chinese lubrication technology is moving from usable → easy to use → leading.
