Single lip seal with the labyrinth between the sheet part and
the rubber lip which conducts the contact sealing. The friction and speeds are the same as with RS but provides much
better protection against the rough impurity particles. This
is very good sealing system: the sheet part protects the seal
from the soil, dust and rough particles. At the same time
makes the labyrinth with the rubber part. The rubber part
provides contact sealing which prevents penetration of finer
impurities, water, moisture, steam etc. Suitable for neutral
conditions because of the presence of the foreign materials.
It is used with the Y bearing (standard) and deep groove ball
bearings.
