Depending on the size of the clutch, the installation must provide for an air gap of between 0.2 and 0.5 mm between the drive hub and the armature disc.
If a SUCO output drive hub is not used, it is important to ensure that there are clearance holes to accommodate the rivet heads when installing the armature disc. The armature disc is centred by the screws which hold the spring disc to the output component.
When the armature disc is installed, it must remain free to move axially against the return spring.
Construction and mode of operation
The basic model of electromagnetic clutch with bearing consists of stator body with cast-in coil and connection cable, the input drive hub with support bearing, and the armature disc to which the return spring is riveted. Because it contains a bearing, it is not necessary to center the stator body on the input drive hub when using this model.
