Lubrication Information
General Properties: The lubricant used in most Torque-Hub
®
drives should be petroleum
based gear fluid containing anti-oxidation, anti-foaming and extreme
pressure additives. The lubricant should have a minimum viscosity
index of 95cst and maintain a minimum viscosity of 40cst under
normal operating conditions. Some applications require special
considerations; consult the machine manufacturer and Oerlikon
Fairfield for more additional information.
The table below lists the recommended viscosities for various
ambient operating temperatures. These recommendations are
based on temperature rise of 50° to 100°F at normal operating
conditions.

Footnotes
1. For operation in this ambient temperature range, synthetic oil is recommended with a pour point of
10°F lower than the minimum ambient temperature.
2.
For operation in this ambient temperature range, synthetic oil is recommended for proper lubricant
life at elevated temperatures.
