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 95 cst and maintain a minimum viscosity
of 40 cst 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.
