Short bearing life is a frequent issue in many industrial applications.
From what we’ve seen in real cases, the problem is often not the bearing itself, but how it is lubricated.
Some common reasons:
In many situations, replacing bearings repeatedly doesn’t solve the root cause.
It’s better to evaluate operating temperature, load, and environment when selecting grease.
A small adjustment in lubrication can sometimes make a big difference.
In actual applications, many customers working on robotic systems encounter a common issue: after a period of operation, joints start to produce noise, sometimes with slight vibration.
At first, this is often considered a mechanical problem. But in many cases we’ve seen, lubrication plays a big role.
Typical causes include:
In practice, this kind of issue is not unusual. Many customers overlook lubrication at the early stage.
Choosing a stable, low-volatility grease designed for precision parts usually helps a lot.
If you’re dealing with a similar situation, it’s worth checking the lubrication first.
Manufacturers in automotive electronics and precision components are facing increasing pressure on cost and supply chain stability.
Traditional reliance on Molykote and Klüber is being challenged by high-performance local alternatives.
EUBO specialty greases offer comparable performance with faster response and better cost efficiency.

Conclusion: Meets automotive and precision application requirements
Noise, Vibration, and Harshness (NVH) are critical factors in the user experience of smart home appliances and automotive interiors. Plastic gears (made of POM, Nylon, or PC) are widely used for their lightweight and cost-effective properties, but they often face challenges such as friction noise and material stress cracking.
Why General Lubricants Fail? Many standard mineral-oil-based greases are incompatible with plastics, leading to "stress cracking" or swelling of the gears. Selecting the right Synthetic Plastic Gear Grease is essential for long-term performance.
Why Choose EUBO Specialty Lubricants?
At EUBO, we have developed a series of high-performance greases specifically engineered for micro-motors and plastic gearboxes:
Excellent Material Compatibility: Our synthetic base oils are tested against various plastic substrates to ensure zero corrosion or degradation.
Superior Damping & Noise Reduction: EUBO grease forms a stable lubricating film that cushions gear impacts, significantly reducing mechanical noise.
Wide Temperature Range: Our formulas remain stable from -40°C to +150°C, ensuring smooth operation in extreme climates.
Long-Life Performance: High oxidation stability prevents the grease from drying out or leaking over time.
Applications: From robot vacuum cleaners and smart locks to automotive actuator motors, EUBO provides the silent power behind smooth motion.

High-temperature fluorine-based grease, also known as perfluoropolyether (PFPE) grease, is a high-performance lubricant formulated from PFPE base oil and specific fluorinated thickeners. The molecular structure of PFPE is dominated by carbon-fluorine (C–F) bonds, which impart the grease with distinctive performance characteristics:
High-Temperature Resistance:
High-temperature fluorine-based grease remains stable under extreme temperature conditions. Its operating temperature range is broad, typically from -50°C to +250°C, and some high-end products can withstand temperatures above 300°C without oxidation, decomposition, or evaporation.
Chemical Inertness:
Due to the high electronegativity of fluorine atoms, PFPE exhibits excellent resistance to most chemicals, showing minimal reaction with acids, bases, organic solvents, or strong oxidizers. This effectively prevents degradation or failure of the grease when in contact with these media.
In modern industrial systems, the application value of high-temperature fluorine-based grease is undeniable. It is widely used in aerospace, semiconductor manufacturing, precision instruments, new energy, chemical, medical equipment, and military industries, and plays a crucial role in the following key scenarios:
High-temperature operations: Lubrication of bearings, chains, valves, and seals in equipment such as metallurgy, glass manufacturing, ceramic sintering, heat treatment furnaces, and high-temperature ovens.
Extreme chemical environments: Equipment operating under aggressive chemical conditions, including chemical reactors, pharmaceutical equipment, and electroplating production lines.
High-vacuum environments: Applications requiring stable lubrication in semiconductor chip manufacturing, vacuum coating, and scientific research equipment.
Precision systems with strict lubrication requirements: Systems that demand cleanliness, durability, and precise lubrication, such as precision machine tools, optical instruments, aerospace components, and medical devices.

With the advancement of modern industry, machinery is evolving toward high precision, high efficiency, ultra-large and ultra-small sizes, high speed, heavy load, energy saving, high reliability, and ease of maintenance. As a result, the operating temperatures of friction points in machinery are steadily increasing, placing greater demands on the high-temperature resistance and anti-wear performance of lubricating greases.
Most commonly used greases—such as calcium-based, sodium-based, and barium-based single-metal soap greases—tend to soften, bleed, or volatilize under high temperatures, losing their lubrication effectiveness. This often leads to equipment wear, increased noise, or even damage, adversely affecting normal production operations.
To address these challenges, EUBO has introduced its high-temperature grease, designed to provide reliable lubrication under extreme operating conditions.
EUBO High-Temperature Grease is a high-viscosity perfluoropolyether (PFPE) grease thickened with polytetrafluoroethylene (PTFE) and refined with special anti-corrosion additives. This fluorine-based grease is specifically designed for bearings, gears, and components requiring lifetime lubrication under high-temperature, high-speed, heavy-load, and chemically aggressive environments. It offers excellent chemical inertness, durability, and low volatility, with an operating temperature range of -50°C to 250°C.
Wide Temperature Lubrication: Formulated with medium-viscosity modified silicone oil, it provides long-lasting and superior lubrication from -50°C to 250°C, effectively reducing wear and maintaining precise part alignment.
Strong High-Temperature Adhesion: Prevents grease from dripping under high heat, maintaining a continuous lubricating film.
Excellent Thermal Stability: Resistant to deterioration, it does not carbonize, coke, discolor, emit odors, or bleed, ensuring reliable long-term operation in high-temperature environments.
High Film Strength and Load Capacity: Offers a load-bearing capacity three times that of conventional greases. Lubrication is long-lasting, reducing the need for frequent replenishment and lowering maintenance costs.
Good Colloidal and Shear Stability: Exhibits very low oil separation, preventing contamination of other components. The consistency changes minimally after shearing.
Wide Compatibility: Compatible with most materials, including rubber, plastics, and metals, enabling broad application.
Chemical and Water Resistance: Insoluble in water and most solvents, and compatible with engineering plastics and elastomers. Stable against strong acids, strong bases, and halogens, making it suitable for lubrication and sealing in corrosive environments.
Lubrication and friction reduction for bearings, gears, guides, cams, and other components operating under extremely high temperatures and heavy loads where conventional greases cannot perform.
Especially suitable for lubrication of bearings in:
Film stretching machines
Heat-setting conveyor belts
Corrugated paper machines
Hot air blowers
Hot oil pumps
High-temperature motors
