How the sliding bearing life calculator works

The calculator is divided into three consecutive steps:

  1. Selecting the type of sliding bearing
  2. Entering the dimensional characteristics
  3. Determining the operational characteristics

After selecting the type of bearing, you will be prompted to enter the dimensions. Depending on the type of bearing, these are the following fields:

All fields in this section are mandatory and further calculation is impossible without them.

After entering the dimensions, click on the link to go to the next section Operational Conditions.

All fields in this section are already filled in with default values, which you can change according to your operational characteristics. Already at this stage, at the bottom of the calculator, the service life of the sliding bearing is calculated. By changing the operating parameters, you can observe the change in the calculated service life.
