4.14.5 Regreasing the labyrinth seal
Output shaft
The following figure shows an example of a regreasable radial labyrinth seal (taconite).
• Single oil seal with radial labyrinth seal
• Used in
very dusty
environments with abrasive particles
Position of
greasing points
Regreasable sealing systems are usually equipped with taper greasing nipples accord-
ing to DIN 71412 A. Regreasing must be carried out at regular intervals. The greasing
points are located near the output shaft, see following figure:
Refilling grease
Regreasable sealing systems can be refilled with lubricating grease. Use moderate
pressure to force grease into each lubrication point until new grease leaks out of the
sealing gap.
Used grease, including contaminants and sand, is in this way pressed out of the sealing
gap.
