7.4 Test run

Avoiding mechanical damage to bearings
Regularly inspect all machines for any mechanical damage. Especially observe that the
bearing replacement intervals and relubrication intervals, respectively grease change intervals
or oil change intervals specified by the machine manufacturer are maintained.
Replace the bearings once they have reached their nominal service life or verify that they are
mechanically in good working order as part of an inspection.
● Where bearings are sealed for life, there is a guarantee that the rated service life is achieved
● The theoretical nominal service life of the bearings can be taken from the data sheet of the
● Where machines are subject to externally applied forces (e. g. the force on a drive belt or
● For all other machines, the rated service life of the bearings is at least 40,000 hours.
● For bearings with external oil supply, monitor the lubrication system to ensure that it is
7.4 Test run
After installation or inspection, carry out a test run:
1. Start up the machine without a load. To do this, close the circuit breaker and do not switch
2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue

Switching the machine off again while it is starting up and still running at slow speed should
be kept to a bare minimum, for example for checking the direction of rotation or for checking

Allow the machine to run down before switching it on again.

Avoiding mechanical damage to the cylindrical roller bearing
Under all circumstances maintain the minimum load on cylindrical roller bearings of 50%
corresponding to what is specified in the catalog.
