Calculate a Bearing's Lifetime

Select the lifetime calculation before selecting a bearing type. After selecting the bearing type, select a dynamic or static load to a bearing.

For a dynamic load you must define the values of the radial force, axial force and the rotational velocity. The software calculates the nominal lifetime. Nominal lifetime means according to ISO definition a lifetime, which 90 % of a large amount of identical bearings are expected to reach.

For a static load you must define the values of the radial force and the axial force. The software calculates the basic static load rating. Basic static load rating is defined as a static load which causes a permanent deformation at the contact point of maximum load in the rolling element of 0.0001 times the diameter of the element.

1. Select the Perform age calculation before selecting the bearing.
2. Select the bearing type.
3. Click Next.
4. Select Dynamic load or Static load.

   Select the New selection you can select a new bearing size for the calculation.

5. Enter the values of the load.
