Kluber high-temperature grease has long established its leading position in the industrial lubricant market. With its ability to operate stably in extreme conditions, the Kluber high-temperature grease product line is the top choice for businesses. Let’s explore the reasons why Kluber high-temperature grease is dubbed the gold standard in the industry.
In the modern industrial manufacturing environment, machinery and equipment often operate under high pressure, high speed, and especially extremely harsh temperatures. These factors pose enormous challenges to the maintenance and lifespan of bearing systems, gears, and other moving parts. Traditional lubricants quickly break down, evaporate, or leak out, leading to premature wear, sudden failure, and disruption of the entire production line.
Recognizing the critical need for a superior lubrication solution, Klüber Lubrication developed the Kluber high-temperature grease line. This is not just an ordinary lubricant, but a combination of advanced chemical technology, premium synthetic base oils, and specialized additive systems researched in the world’s leading laboratories.
This article will delve into a comprehensive analysis, thoroughly explaining why Kluber high-temperature grease has surpassed all rivals to become the “gold standard” in industrial lubrication. We will explore core technical aspects such as thermal stability, anti-wear performance, practical applications in heavy and textile industries, and provide guidance on optimal product selection and use.
1. Overview of Kluber High-Temperature Grease and the Core Difference
Kluber high-temperature grease is a lubricant product line specifically designed to maintain stable performance and structural integrity when exposed to working temperatures ranging from medium to very high, often exceeding 120°C. Kluber’s difference lies not only in simple temperature resistance but also in the philosophy of creating specialized lubrication solutions, perfectly suited to each individual application.
1.1. History and Philosophy of Klüber Lubrication
Klüber Lubrication is a global company based in Germany, with over 90 years of experience in the field of specialty lubricants. Their philosophy is: “Maximizing customer value through specialized lubrication solutions.” Instead of offering mass-market products, Kluber focuses on researching proprietary formulas for the most demanding industries. This specialization is what has built the superior reputation and quality of every Kluber high-temperature grease product.
Kluber does not just sell grease; they sell engineering solutions that help customers reduce maintenance costs, enhance equipment performance, and extend relubrication intervals. This is a key factor in earning the absolute trust of leading original equipment manufacturers (OEMs) worldwide. Close collaboration with OEMs allows Kluber to test and improve its high-temperature grease under real-world conditions, ensuring optimal effectiveness.
1.2. Classification and Exclusive Formulas of Kluber Grease
The Kluber high-temperature grease product line is diverse, mainly classified based on the base oil (Synthetic or Mineral) and the thickener type. Common types include Perfluoropolyether (PFPE) based greases for extremely high temperatures, Polyalphaolefin (PAO) based greases for balanced performance, and Lithium Complex based greases for high mechanical stability.
Each Kluber high-temperature grease formula is a unique combination of three main components: base oil, thickener, and additives. Crucially, the anti-oxidation, anti-wear, and anti-corrosion additives are internally researched and developed by Kluber, providing superior protection that competing products struggle to replicate. This is the secret that helps Kluber high-temperature greases retain their physical and chemical properties even when temperatures exceed 200°C.
1.3. Important Technical Parameters of High-Temperature Grease
When evaluating the performance of Kluber high-temperature grease, core technical parameters must be considered. First is the Service Temperature Range, indicating the maximum and minimum temperature limits within which the grease can operate effectively. The Dropping Point indicates the temperature at which the grease begins to liquefy, a critical parameter for grease operating in furnaces or dryers.
Second is the Base Oil Viscosity, which affects the ability to form a protective oil film at specific speeds and loads. Finally, the NLGI Consistency Class (penetration grade) determines the grease’s stiffness, ensuring it is compatible with the installed pump system and lubrication mechanism. The variety of parameters in Kluber high-temperature grease allows engineers to select the exact product needed for every application.
2. Superior Thermal Resistance and Stability of Kluber High-Temperature Grease
The ability to withstand and maintain lubricating properties under high temperatures is the most outstanding feature and the main reason why Kluber high-temperature grease has become the gold standard. This difference stems from the use of the highest quality components and proprietary blending technology.
2.1. Dropping Point and Service Temperature Range
Premium Kluber high-temperature greases often have a very high, or even “undetermined,” Dropping Point for PFPE (Perfluoropolyether) based greases using PTFE (Teflon) thickeners. This means the grease will not liquefy or structurally deform even when temperatures exceed 250°C. This is a huge advantage compared to ordinary Lithium greases, which typically withstand a maximum temperature of about 120-150°C.
The wide operating temperature range of Kluber high-temperature grease also ensures stable performance in both cold and hot environments. For example, some Kluber products can operate from -50°C up to +280°C without hardening or becoming too soft. This capability minimizes seasonal maintenance risks and ensures smooth machine startup in all climatic conditions.
2.2. Oxidation Resistance and Structural Stability Under High Temperatures
When grease is exposed to high temperatures and air, oxidation occurs, causing the grease to harden, form deposits (carbon residue), and lose its lubricating ability. Kluber high-temperature grease uses highly saturated synthetic base oils (like PFPE, Ester, or PAO) and powerful anti-oxidation additives, effectively counteracting this degradation.
High oxidation resistance means longer relubrication cycles, reducing maintenance frequency and saving operational costs. Furthermore, the complex thickeners in Kluber high-temperature grease create a stable fibrous network that securely holds the base oil, even under intense churning or continuous vibration at high temperatures, preserving the grease’s gel structure.
2.3. Advanced Synthetic Thickener Technology
The thickener acts as the “skeleton” of the grease. Kluber utilizes specialized inorganic or complex thickeners, such as Polyurea, Lithium Complex, or PTFE. Polyurea thickener, an advanced technology, provides superior thermal and mechanical stability, less oil separation, and enhanced water resistance.
Meanwhile, Kluber’s PFPE-based greases use PTFE as the thickener, which has no dropping point and is chemically inert. This combination ensures that Kluber high-temperature grease does not form carbon deposits upon degradation (at extremely high temperatures, it only evaporates without leaving abrasive residues), keeping machine components clean and running smoothly for longer periods.
3. Peak Lubrication Performance in Harsh Environments
The lubricating capability of Kluber high-temperature grease goes beyond just thermal resistance; it also provides comprehensive protection under the toughest working conditions such as heavy loads, exposure to water, chemicals, and dusty environments.
3.1. Load-Carrying Capacity and Wear Protection
The EP (Extreme Pressure) and AW (Anti-Wear) additives in Kluber high-temperature grease are selected and blended in precise proportions. These additives create a protective chemical film on the metal surface when pressure suddenly increases, preventing direct metal-to-metal contact.
In standard tests such as the Four-Ball Test, Kluber high-temperature grease consistently yields superior results in terms of weld point and wear scar compared to competing products. This demonstrates that Kluber grease can effectively protect bearings operating under shock loads or heavy vibrations, especially crucial in presses, crushers, and heavy equipment.
3.2. Excellent Water Resistance and Washout Protection
In many industries, equipment is subjected not only to heat but also to steam, cold water, or coolant liquids. When grease dissolves or washes out, the protective layer disappears, leading to rust and failure. Kluber high-temperature grease utilizes excellent water-resistant formulas.
Kluber’s Calcium Sulphonate Complex based greases, for example, have inherent rust and corrosion protection, along with high adhesion. The grease adheres tightly to metal surfaces, creating a physical barrier that prevents water penetration and subsequent damage. As a result, bearing life is significantly extended, even in humid environments or under cleaning water sprays.
3.3. Energy Savings and Extended Equipment Life
Using high-quality Kluber high-temperature grease is not just an expense but an investment that yields long-term economic benefits. Thanks to a low friction coefficient and stability at high temperatures, Kluber minimizes frictional drag during operation, helping machinery consume less energy.
When friction is reduced, the bearing’s operating temperature also decreases, thereby slowing down the aging process of the grease and the metal itself. Studies have shown that switching to the appropriate Kluber high-temperature grease can double or triple the bearing life, minimizing the cost of expensive component replacement and labor costs for maintenance.
4. Widespread Practical Applications of Kluber High-Temperature Grease in Various Industries
The flexibility and reliability of Kluber high-temperature grease have made it a trusted product in almost every industrial sector, from those requiring stringent hygiene to those with the harshest working environments.
4.1. Steel and Heavy Industry (Furnaces, Rollers)
In the steel manufacturing industry, the bearings of furnace cars or the rollers in continuous casting lines must withstand extremely heavy loads and temperatures up to 250°C. Kluber’s synthetic-based high-temperature greases and complex thickeners are engineered to meet these challenges.
They provide reliable lubrication for hard-to-reach locations where manual relubrication is hazardous or impractical. The non-carbonizing nature of certain specialized Kluber greases ensures that raceways and rollers do not become clogged, maintaining high precision and production speed.
4.2. Textile Industry and Heat Setting Machines (VieTextile focus area)
The textile industry is a vital sector where machine components in tentering frames, dryers, and sizing machines operate under continuous high heat. Temperatures in drying chambers can reach up to 180°C. If ordinary grease is used, the base oil will quickly evaporate, leading to machine jamming and fabric damage.
Kluber high-temperature grease features specialized formulas for the textile industry, minimizing deposit formation and preventing yellowing or staining of the fabric fibers. We, VieTextile, highly recommend dedicated Kluber product lines to ensure the precision and longevity of conveyor chains, slide rails, and bearings in the high-temperature environment of textile machinery.
4.3. Automotive and Manufacturing Industries (Bearings, Joints)
In the automotive industry, Kluber high-temperature grease is widely used in critical components such as wheel bearings, constant velocity (CV) joints, and transmission mechanisms. These parts require grease to withstand high shear forces, high speeds, and heat generated by brake friction or engine operation.
Kluber grease not only protects components from heat and wear but also provides excellent protection against Noise, Vibration, and Harshness (NVH). This contributes to improving the overall quality and driving experience of the final product.
4.4. Food and Pharmaceutical Industries (NSF H1 Certified)
For applications with a risk of incidental contact with food or pharmaceuticals, Kluber offers a special line of Kluber high-temperature grease that meets NSF H1 certification. This grease is formulated from non-toxic, odorless, and tasteless ingredients, ensuring absolute safety for consumers.

5. Differentiating Kluber High-Temperature Grease from Other Conventional Greases
The difference between Kluber high-temperature grease and other lower-cost industrial greases is not just in price but in performance, lifespan, and the Total Cost of Ownership (TCO).
5.1. Base Oil Difference (Mineral vs. Synthetic)
Most conventional greases use mineral oil, which has a non-uniform molecular structure. When the temperature increases, mineral oil quickly degrades, evaporates, and leaves carbon deposits. Conversely, most premium Kluber high-temperature greases use synthetic base oils (PAO, Ester, or PFPE).
Synthetic oils have a uniform molecular structure, providing superior thermal stability and viscosity over a wide temperature range. They evaporate less, have a lower friction coefficient, and maintain lubricating properties many times longer than mineral oils, ensuring the excellent lubricating efficiency of Kluber high-temperature grease.
5.2. Specialized Additives and Additive Technology
While conventional greases use basic additive packages, Kluber invests heavily in developing specialized additive packages. These additives are not just ordinary anti-wear or anti-rust agents but advanced thermal stabilizers, antioxidant agents, and adhesion enhancers optimized for each specific Kluber high-temperature grease line.
For instance, some Kluber products contain micro-sized solid lubricating particles like PTFE or Molybdenum Disulfide (MoS2), which help maintain the protective film even if the main base oil breaks down, ensuring continuous protection for the equipment.
5.3. Life Cycle Cost (LCC) Analysis
Although the initial cost of Kluber high-temperature grease may be higher than conventional grease, when analyzing the Life Cycle Cost (LCC), Kluber proves to be the more economical choice. LCC includes the cost of buying grease, maintenance costs (component replacement, labor), and downtime costs.
Because Kluber’s relubrication cycle is 2-5 times longer, equipment lifespan is increased, and the risk of sudden failure is minimized, the Total Cost of Ownership (TCO) for businesses using Kluber high-temperature grease is proven to be significantly lower. Choosing Kluber high-temperature grease is an effective asset management strategy.
6. Guide to Correctly Selecting and Using Kluber High-Temperature Grease
Correctly selecting and using the right type of Kluber high-temperature grease is crucial to maximizing product performance and ensuring machine longevity. Mistakes in selection can lead to serious consequences.
6.1. Criteria for Selecting the Right Grease for Specific Applications
When selecting Kluber high-temperature grease, engineers must consider four main factors:
- Operating Temperature: Determine the maximum and minimum temperature of the application to select grease with the appropriate Service Temperature Range.
- Load and Speed: Heavy loads require grease with high base oil viscosity and strong EP/AW additives. High speeds require lower viscosity grease to reduce friction.
- Environment: Exposure to water, chemicals, or dust requires grease with high washout resistance and corrosion protection (such as Calcium Sulphonate based grease).
- Compatibility: Ensure the new Kluber grease is compatible with old grease and sealing materials (seals), especially when switching to synthetic greases like PFPE.
Consulting the Kluber Product Selector Chart or directly seeking advice from VieTextile’s specialists is an indispensable step to choosing the most suitable Kluber high-temperature grease.
6.2. Standardized Relubrication Procedure
Relubrication must strictly follow the guidelines of the equipment manufacturer (OEM) or Kluber. Using too much grease is as dangerous as using too little. Excessive grease can increase friction, raise temperature, and destroy the grease structure.
Before relubricating with Kluber high-temperature grease, the old grease should be completely removed (if possible) to avoid mixing incompatible types. Use clean lubrication tools and ensure the relubrication quantity is accurate. Correct relubrication helps Kluber high-temperature grease maximize its lifespan and protective capabilities.
6.3. Common Mistakes When Using High-Temperature Grease
A common mistake is using the same Kluber high-temperature grease for every application. Since Kluber specializes its products, each grease is optimized for a specific operating condition (e.g., grease for dusty environments differs from grease for extreme high temperatures).
The second mistake is neglecting thickener compatibility. Mixing Lithium-based grease with Polyurea-based grease can soften the grease and significantly reduce the Dropping Point, damaging the thermal resistance advantages of Kluber high-temperature grease. Always check compatibility before switching grease.
