High-Temperature Grease Selection for Industrial Applications

Selecting and applying the right industrial lubricant isn't just about following a datasheet. It's about understanding what happens inside a bearing at temperature, under load, and over time. High-Temperature Grease Selection is where that understanding pays off.

TL;DR

  • Understand high-temperature grease selection — and why it matters for equipment reliability
  • Know the key differences in temperature ranges by grease type
  • Apply the right recommended klüber products for your operating conditions

High-Temperature Grease Selection

Operating temperature is one of the most critical factors in grease selection. As temperature increases, grease life decreases exponentially — a rule of thumb is that grease life halves for every 15°C increase above 70°C. Selecting the right high-temperature grease can mean the difference between reliable operation and catastrophic bearing failure.

Temperature Ranges by Grease Type

Grease Type Max Continuous Temp Typical Application
Lithium Soap 120-130°C General industrial bearings, electric motors
Lithium Complex 150-180°C Higher-temp industrial bearings
Polyurea 160-180°C Electric motors, sealed bearings
Bentonite (Clay) 180-200°C Oven conveyors, kiln cars
PTFE/Silicone 200-220°C Low-load, high-temp applications
PFPE (perfluoropolyether, a chemically inert synthetic base oil used for extreme-temperature and aggressive-chemical applications)/PTFE 250-260°C Extreme temperature, chemical resistance, oxygen service

> Tip

A rule of thumb: for every 15°C increase above 70°C, grease life is cut in half. If your bearing housing is too hot to touch comfortably, check your lubrication — you may be over-greasing or using the wrong product.
