Rotary Seals - Dilanda.it

Cassette Seal
In order to avoid leakage at standstill or low speed, the
TURBO-pattern includes a static edge, which provides
continuous contact line against the shaft. The frictional
loss of the seals provided with TURBO-pattern is
significantly lower than that caused by seals without
hydrodynamic sealing aids. A lower friction does also
allow higher shaft speeds, or provide longer service life.
The Turbo pattern is available in three versions: Bidirectional,
left hand or right hand rotation. The
standard is bi-directional as most applications have
alternating movement of the hub or shaft. If an
application have rotation in one direction only, the
corresponding left or right hand type can be specified.
The direction of rotation is always defined as seen from the
air side.
