Overview

Engineering reference data for Greases Temperature Limits in thermodynamics.

Key Formulas

First Law

$\Delta U = Q - W$

Energy is conserved — heat added minus work done.

Ideal Gas Law

$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Carnot Efficiency

$\eta = 1 - T_C/T_H$

Maximum efficiency between two temperatures.

Variables

$V$	Volume	m³
$T$	Temperature	K

Grease Type Temperature Limits

The table below summarizes the temperature limits for common grease thickeners. These limits are critical for selecting the right grease for a specific application, as operating beyond these temperatures can cause the grease to break down, losing its lubricating properties.

6 rows

Typical maximum operating temperature limits for common grease thickeners.
Grease Thickener	Temperature Limit(°F)	Temperature Limit(°C)
Aluminum	180	82
Barium	225	107
Calcium	170	77
Lithium	300	149
Sodium	250	121
Synthetics	< 500	< 260
