2.5. Radial force diagrams
All bearings are designed for a service life of 20,000 h L
10h
. The load values specified below may thereby not
be exceeded. The permissible radial forces F
R
are valid only for the horizontal installation of the motor without
additional axial forces.
Furthermore, the specified average speeds must be adhered to reach the grease consumption period of 20,000
h under the following conditions:
low-vibration applications
horizontal installation
oscillatory bearing motion in which at least one pivot angle of 180° is performed
Continuous bearing temperatures <120° C.
Axial loading on the motor shaft is generally not permitted.
No axial forces may develop when mounting clutches, pulleys, etc. on the motor shaft!
2.5.1. Sample diagram
Sample diagrams:
Driving forces x = 30 mm from the shaft shoulder
Bearing service life 20,000 h, shaft with parallel key groove
Explanation of the sample chart:
The potential maximum speed of the bearing can be calculated via radial force Fr of the application in
characteristic "ball bearing".
At a radial force of 500 N with a driving force point of x = 30 mm from the shaft shoulder, a maximum speed of
1200 rpm results.
