Siemens SIMOTICS S-1FK2 Configuration Manual

3.6 Radial and axial forces
3.6.1 Axial forces
When using, for example, helical toothed wheels as drive element, in addition to the radial force,
there is also an axial force on the motor bearings.
The following axial forces on the shaft extension are permitted.
Motor Static axial forces in N
1FK2☐03 75
1FK2☐04 100
1FK2☐05 120
1FK2☐06 200
1FK2☐08 300
1FK2210 450
The speci󹪝ed axial forces are determined by the spring loading and therefore also apply to motors with
holding brake.
Note
Applications with an angular toothed pinion directly on the motor shaft are not permitted with
standard bearings if the permissible axial forces are exceeded.
3.6.2 Radial forces
Permissible radial forces
As a result of the bearing arrangement, the 1F☐2 is designed for aligned forces. Forces such as
these occur for belt drives, for example.
All radial forces always refer to aligned forces.
NOTICE
Motor damage caused by circulating forces
Circulating forces can cause bearing motion, and therefore damage the motor.
• Circulating forces are not permissible.
