High-Temperature Grease: Types, Specifications, and Selection

High-temperature grease is a lubricating grease designed to remain stable when equipment operating temperatures exceed the limit of standard multipurpose grease. It is evaluated by working temperature range, dropping point, extreme pressure (EP) performance, and oxidation resistance. Hangzhou Xingang Lubrication Technology Co., Ltd. is a national high-tech enterprise established in 1993 and headquartered in Hangzhou, Zhejiang, China. The company manufactures high-performance lubricating greases and industrial lubricants under the XINGANG brand. This guide explains the XINGANG high-temperature grease portfolio, its specifications, and how to select grease for high-temperature bearings, gears, and other industrial equipment.

Why High-Temperature Grease Selection Matters

When heat exceeds the design limits of a grease, the grease can soften and flow out of the lubrication point, oxidize, form carbon deposits, or lose the load-carrying film that protects bearings and gears. These failures are especially costly in industries with continuous operation such as metallurgy, ports, automotive, machinery, textiles, printing and dyeing, paper making, sugar refining, chemicals, and power generation. A high-temperature grease with a high dropping point reduces these risks because the dropping point indicates the temperature at which the grease structure collapses.

Industry Context and Market Signals

The high-temperature grease category is a significant part of the global lubricants industry. According to a market report cited through Vertex AI Search, the global high-temperature grease market was valued at approximately USD 28.04 billion in 2025 and is projected to reach USD 48.71 billion by 2035. Market Research Future reports that Asia Pacific led the high-temperature grease market in 2025 with a 38% global share, driven by automotive manufacturing hubs.

Thickener data also explains why grease selection is changing. According to STLE and Grease Market Trends, lithium grease accounted for 38.3% of global production in 2024 and lithium complex grease accounted for 18.6%, giving the two families a combined 56.9% share. Calcium sulfonate complex grease production grew by 7.7% in 2024, gaining traction in heavy-duty industrial applications because of its water resistance. Lithium prices surged by 80% to 120% between 2021 and 2023, according to STLE, which has led manufacturers to evaluate polyurea and calcium sulfonate alternatives for high-temperature applications. The automotive segment captured 42.6% of high-temperature grease market share in 2025, the largest application category. In addition, China's finished lubricant exports rose by 10% to 260,000 metric tons in 2024, according to Lubes'N'Greases and China Customs data.

For procurement teams, two reference standards help frame the decision: ASTM D3336 is the standard method used to evaluate lubricating grease life in ball bearings at elevated temperatures, and DIN 51502 classifies high-temperature greases by maximum operating temperature using letters from K to U.

XINGANG High-Temperature Grease Portfolio

XINGANG high-temperature grease options are available in four thickener families: lithium grease, lithium complex grease, polyurea grease, and calcium sulfonate complex grease. Each family has a defined working temperature range, dropping point, and load capacity.

Lithium Grease (XG/L1, XG/L2)

Lithium grease is a multipurpose grease made with lithium and mineral oil. XINGANG Lithium Grease models XG/L1 and XG/L2 have a working temperature range of -20°C to 120°C and a dropping point of at least 180°C. Applicable industries include multi-purpose, automotive, metallurgy, and power tools. Because its upper temperature limit is lower than the other high-temperature families, lithium grease is best matched to moderate heat conditions.

High-Temperature Lithium Complex Grease (XG/HP, XG/HP-R)

Lithium complex grease is a high-temperature extreme pressure lithium complex grease. XINGANG models XG/HP and XG/HP-R have a working temperature range of -20°C to 180°C, a dropping point of 300°C, and a PD value of 315 kgf. It is suited to automobile and metallurgy applications that need high-temperature stability and anti-wear protection.

High-Temperature Polyurea Grease (XG/U1, XG/U2, XG/U5, XG/U6, XG/U10, XG/U17, XG/U18)

Polyurea grease is a high-temperature polyurea grease made with polyurea, mineral oil, and synthetic oil. XINGANG models XG/U1, XG/U2, XG/U5, XG/U6, XG/U10, XG/U17, and XG/U18 have a working temperature range of -20°C to 200°C and a dropping point of 260°C. It is used in metallurgy, chemical, textile, printing and dyeing, automobile, mining, oil field, coastal defence, sugar refining, paper making, and plastic industries.

High-Temperature Calcium Sulfonate Complex Grease (XG/C4, XG/C5)

Calcium sulfonate complex grease is a high-temperature calcium sulfonate complex grease made with calcium sulfonate and 150 BS oil. XINGANG models XG/C4 and XG/C5 have a working temperature range of -20°C to 250°C, a dropping point of 330°C, and a PD value of 500 kgf. It is suited to mining, machinery, and automotive applications that require high load-carrying capacity.

How to Select a High-Temperature Grease

Selection should start with the actual application conditions, not with a generic grease category. The following steps are a practical path for a procurement or engineering team.

1. Define the bearing or gear operating temperature, including peak temperature. Match the grease working temperature range to that condition.
2. Confirm the load and impact condition. For heavy or impact loads, choose a grease with a high PD value or extreme pressure properties.
3. Assess water exposure. For humid or water-splash environments, a grease with strong anti-water washout performance is needed.
4. Check the lubrication system. XINGANG high-temperature greases are compatible with centralized lubrication systems, grease guns, gearbox spray equipment, and grease injection or replacement equipment.
5. Verify the certification level. XINGANG lithium grease, lithium complex grease, calcium sulfonate complex grease, and polyurea grease products are covered by IATF 16949:2016 certification number 2024A3002.
6. Request a sample or an OEM formulation before finalizing the specification.

For steel plant conditions, XINGANG application guidance recommends good high-temperature thermal stability, strong anti-water washout performance, stable extreme pressure anti-impact property, low carbon residue after high-temperature aging, and no corrosion to metal substrates.

Use Cases: Bearings, Gearboxes, Steel Plants, and Automotive Lines

XINGANG high-temperature grease is used for lubrication of bearings in continuous casting, rolling mills, kiln cars, gearboxes, conveyors, vibrating screens, and other high-temperature and heavy-load lubrication points.
