Gear Oil Viscosity Calculator
We often have gear boxes where the correct viscosity gear oil is not known either because it is a used box and came without the manual, or it is now being used in a different setup from its original design.
This calculator can be used to determine the right viscosity for the gear box with under the conditions we determine. This provides a starting point. The viscosity can be modified slightly up or down until you have the reducer working at its lowest temperature.
To use the calculator:
- Select the type of lubrication: Splash or circulation
- Select the type of reduction: Simple or multiple
- Select the horsepower range
- Select the speed
The correct oil viscosity will be shown in the results.
