How to Select High Temperature Grease: Professional Selection Guide by Temperature, Load & Speed

Blind purchase of high-temperature grease will lead to insufficient lubrication performance or waste of cost. Different equipment temperature ranges, operating speeds and load conditions require completely different high-temperature grease formulas. This standardized selection guide helps factories and maintenance engineers accurately select the most suitable heat-resistant grease to balance performance and cost.

1. Select by Working Temperature

For continuous working temperature below 180℃: choose lithium complex high-temperature grease, cost-effective and stable. For 180℃–260℃ long-term operation: choose polyurea or bentonite grease with strong anti-carbon ability. For extreme temperature above 300℃: select full synthetic PFPE high-temperature grease to ensure no failure.

2. Select by Operating Load

Light-load and high-speed precision equipment: use low-viscosity smooth high-temperature grease to reduce noise and friction. Heavy-load and impact equipment: choose high-temperature grease with extreme pressure anti-wear additives to avoid metal scratching and sintering under high heat and heavy pressure.

3. Select by Operating Speed

High-speed bearings and motors: polyurea grease is preferred for long-life and low-sludge performance. Low-speed and high-torque machinery: lithium complex or bentonite grease with strong adhesion is more suitable.

4. Select by Working Environment

Dusty and dry high-temperature workshops: focus on anti-carbon and dust sealing performance. Humid and high-temperature environments: prioritize high-temperature grease with waterproof and rust-proof functions to avoid corrosion failure.
