AHU Motor Bearing

Hi Guest,

You will need to provide some additional data like:

- Bearing designation (both bearings if they are different)

- What type of lubricant is used in the bearing (designation)

- Nominal Running Speed

- Nominal Temperature

- Are there any additional external loads on the motor (apart from the torque it delivers), if so you need to provide a sketch of the layout of the motor with bearing span and the applied point of the load.

Most bearing catalogues (i.e. FAG, SKF) would be able to show you how to calculate bearing life and most of these are also online.

Here is a link to the SKF website:

Select for example calculate on the left and you will be able to perform a simple life calculation.

In addition

You may have to consider if it is belt drive or direct drive application
