Sealing a high frequency<br />
grinding spindle<br />
The GMN Labyrinth Seal “L” Type has to<br />
protect the high precision bearings against<br />
grinding chips and lightly splashing liquids.<br />
The excess pressure caused by the oil mist<br />
lubrication increases the sealing efficiency.<br />
To protect the seal against splashing liquids<br />
when the spindle is stationary an additional<br />
front plate should be used.<br />

Sealing a drilling sleeve<br />
The grease lubricated bearings have to be<br />
protected against cutting oil and chips.<br />
Due to the vertical mounting position the<br />
flange must be designed correctly because<br />
it is not possible to protect the inside against<br />
vertical splashing liquids by an uncovered<br />
non-contact seal.<br />

Typical Applications<br />
Sealing a conveyer roller<br />
The grease lubricated ball bearing <strong>of</strong> the<br />
roller has to be protected against dust and<br />
coarse granular contamination from the<br />
outside.<br />
Mounting<br />
For mounting a bushing is used to push<br />
the seal onto the shaft and into the housing<br />
in one operation. To reach wobblefree<br />
running make sure that the inner ring is<br />
square against the shoulder <strong>of</strong> the shaft.<br />
