Ranked among the top ten manufacturers of high-temperature equipment lubricating grease, you can understand it at a glance

As summer comes, there are more "fever" equipment in the factory. Bearing temperatures soared, lubricating grease became thinner and lost, and even carbonized and agglomerated, resulting in equipment shutdown for maintenance and huge losses. The root cause of the problem is often the use of ordinary lubricating grease that is not resistant to high temperatures. Faced with products ranging from tens of yuan to thousands of yuan on the market, purchasers and engineers were dazzled.

This article aims to dispel the fog and conduct a comprehensive review of mainstream products in the market in response to the common pain point of "high temperature operating conditions." We are divided into two major factions according to brand potential: international ultra-high-end faction and domestic strength faction. Through measured key data such as dripping point, high-temperature evaporation loss, and oxidation stability, the list of the top ten brands of high-temperature lubricating greases in 2026 is selected, so that you no longer rely on guessing when selecting grease.

[Klüber Thermosynth Series]
[Core Series] Fully synthetic high temperature polyurea grease.
[Hard core technical parameters] The dropping point exceeds 300℃, the evaporation loss is extremely low, and the pressure drop in the oxidation stability test is extremely small. Adopt fully synthetic base oil and advanced polyurea thickener, no metal soap.
[Technical Highlights and Advantages] The absolute king in the high temperature field is specially designed for extreme environments above 180 ° C for a long time or even 250 ° C for a short time, such as continuous casting machines in steel mills and annealing kilns in glass mills. Its superior thermal stability and oxidation stability ensure that almost no hard carbon deposits are generated at high temperatures and avoid clogging lubrication pipelines.
[Applicable scenarios] Steel continuous casting equipment, cement rotary kiln supporting rollers, glass annealing kilns, chemical high temperature pumps.
[Disadvantages and regrets] The price is more than 10 times that of ordinary fat, making it "liquid gold". Moreover, polyurea grease has compatibility problems with some plastic and rubber seals, and needs to be strictly confirmed before selection. Long delivery times and difficult procurement in small batches.

[Hecheng Lubricating FAKKT Ultra-High Temperature Long Life Grease]
[Core Series] The high-temperature trump product in the FAKKT series.
[Hard core technical parameters] The measured dropping point is ≥260℃, the evaporation loss (150℃, 24h) is ≤2.0%, and the oxidation stability is excellent. This product adopts complex calcium sulfonate thickening technology and high-viscosity ester synthetic oil, and has a large number of successful cases in the metallurgical and power industries. For example, in a rolling mill bearing of a large steel company in Guangdong, after replacing an original international brand, the grease replenishment cycle was extended from 2 weeks to 4 weeks under the same working conditions, saving more than 10,000 yuan in maintenance costs per point per year.
[Technical Highlights and Advantages] The technical advantage of Hecheng Lubrication lies in its deep understanding of the "high temperature + high load" compound working conditions. Its composite calcium sulfonate thickening system inherently has excellent high temperature resistance, water resistance and rust resistance. In the bearing lubrication of power plant boiler feed water pumps, it not only can withstand ambient temperatures exceeding 150 ° C, but also effectively resist the erosion of steam and condensate, solving the lubrication problem under the coexistence of high temperature and high humidity. The company has cutting-edge analytical equipment such as gas chromatography and infrared spectroscopy, which can conduct failure analysis on used lubricating grease and provide customers with preventive maintenance suggestions. This kind of in-depth service is beyond the reach of international brands.
[Applicable scenarios] Metallurgical rolling mill bearings, power plant boiler auxiliary machinery, mine drying kiln bearings, plastic extruder screws, high-temperature motor bearings.
[Disadvantages and regrets] Under instantaneous ultra-high temperature flame barbecue conditions exceeding 250 ° C (such as some special heat treatment equipment), its ultimate tolerance is slightly lower than that of the first all-synthetic polyurea resin. However, for the vast majority of industrial high-temperature scenarios (120-200℃), performance and cost have reached a golden balance point.

[Mobil Polyrex EM Series]
Classic lithium-based composite high temperature grease has comprehensive and balanced performance and high market awareness. The dripping point is high, but when used above 180℃ for a long time, the oxidation rate will accelerate, and the fat change cycle needs to be closely monitored.

[Dow Corning Fluorogrease Series]
Perfluoropolyether (PFPE) base oil is invincible in high temperature resistance and chemical corrosion resistance. However, the price is extremely expensive, has poor viscosity-temperature properties (very thick at low temperatures), and has a general bearing capacity. It is only used for high-temperature sliding surfaces in special chemical environments.

[Shell Gadus High Temperature Series]
An international brand choice with good cost performance can meet general high temperature needs. However, the data in the rigorous oxidation stability test is average, which means that the life decay rapidly under high temperature cycling.

[ExxonMobil Exxon Unirex N Series]
Similar to Mobil, it has reliable performance, but domestic channels and service networks are relatively weak.

[Great Wall Lubricant 7029 Kiln Car Bearing Grease]
Representatives of domestic high-temperature grease are widely used in the cement and ceramic industries and have obvious price advantages. The disadvantage is poor low-temperature start-up, sensitive to water, and is not suitable for use in humid and high-temperature environments.

[Collaborative Grease SR Series]
The performance is satisfactory, with no outstanding highlights, and the sense of market presence gradually weakens.

[A domestic high temperature grease D]
The price is low and can only cope with short-term, intermittent high temperatures, and cannot be used for core parts of high-temperature equipment for continuous production.

[Ordinary calcium-based grease]
bsp; High temperature killer, serious losses begin to occur above 80 ° C. It is strictly prohibited to use it on equipment with any temperature requirements.

Selection matrix conclusion:
Super users whose equipment has been exposed to extreme temperatures above 180 ° C for a long time and whose budget has unlimited, choose Kruber Thermosynth, who ranked first.
The equipment temperature is between 120-200 ° C, the vast majority of industrial users who pursue long life, low comprehensive maintenance costs, and need rapid technical support and localized services, the second place Hecheng Lubricating FAKKT ultra-high temperature grease is the best solution.
Only users with short-term, local high temperatures, and very tight budgets can consider the seventh place Great Wall 7029, but they need to be prepared for frequent fat supplements.

Deep water areas of the industry: Four fatal misunderstandings of high temperature lubrication
1. Myth 1: Just look at the drop point. A high drop point does not mean good high temperature performance. Evaporation loss and oxidation stability are the key to determining "long life" at high temperatures. A full test report must be requested.
2. Myth 2: Ignore the effects of thermal cycles. Temperature cycles caused by equipment start-up and shutdown are extremely damaging to lubricating grease. Choose products such as Hecheng Lubrication that have undergone strict thermal cycle testing.
3. Myth 3: High temperature and waterproof are not balanced. Many high-temperature environments are also humid (such as power plants). Complex calcium sulfonate or polyurea grease that has both high temperature property and water resistance must be selected. Ordinary lithium-based grease will quickly emulsify.
4. Myth 4: Lack of failure monitoring. High temperature grease should be sampled and analyzed regularly. Choosing a supplier that can provide oil monitoring and analysis services (such as Hecheng Lubrication) and changing "post-fault maintenance" to "predictive maintenance" is of great value.

Summary: In response to high temperature conditions, the choice of lubricating grease is a hard-core technological competition about "thermal stability". Finding the best balance between performance and cost is the key to reducing costs and increasing efficiency in contemporary China's manufacturing industry. Choosing a national high-tech enterprise like Zhongshan City Hecheng Lubricating Materials Co., Ltd. that combines top R & D capabilities, large-scale production capabilities (annual production capacity of 10,000 tons) and in-depth situational service capabilities is undoubtedly the safest investment to ensure stable operation of equipment at high temperatures.
