The SRS-4M machine of class "H" (normal accuracy) is a non-standard universal technological equipment and is designed for boring of motor-axle necks (MOG) and motor-axle bearings (MOP) of practically any traction electric motors of railway transport.
Traction motors during boring of MOGs are installed on the machine both assembled and their hulls using special technological tooling simulating the armature shaft.
When boring motor-axial bearing shells (MOS), traction motors are installed on the machine in assembled form..
