Bearing load during installation

Avoid mechanically overdetermined support of the motor shaft through rigid coupling and additional external support.

When assembling output elements, care must be taken to minimize the load on the shafts and bearing due to shear forces such as radial force F_R and axial force F_A. Axial loads shorten the service life and can lead to malfunctions of the holding brake [+].

Special features when using toothed belt drives:

When using a toothed belt drive, the radial and axial loads on the shaft must not be exceeded. Excessive load can lead to fatigue fracture of the motor shaft. Be sure to read the chapter Technical data.

Storage

The servomotors are equipped with sealed grooved ball bearings. The fixed bearing is located on the B-side of the servomotor and the floating bearing on the A-side; shaft output side of the servomotor. Oscillatory bearing movements < 180 ° shaft rotation are not permissible. Use the Beckhoff load/force calculator for a detailed calculation of the bearing forces on the motor shaft.
