2.3 Axial and cantilever force diagram
2-46
The 1PH4 main spindle motors are provided with a duplex bearing on the drive end
in order to absorb the high cantilever forces from the belt tension.
For a definition, refer to the Configuration Manual ”General Section”.
Axial force
The force diagrams and tables are only valid for standard drive shaft ends; non–
standard drive shaft end dimensions are specified for each particular application
corresponding to the permissible forces.
For force levels going beyond these, please contact your local Siemens office.
Note
When using option L37 (increased speed), make sure that the motors are only
suitable for operation with no cantilever force!
