F SEAL / F SEAL (2F)
Dual sealing, protection cover placed on the inner ring protects against rough impurity particles and makes the labyrinth with the sheet part of the seal; then the sealing S type,
with the labyrinth between the sheet part and the rubber lip
that conducts the contact sealing. The friction and speeds
are the same as with S but has much better protection
against rough impurity particles. It 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 the contact sealing
that prevents the penetration of the finer impurities, water,
moisture, steam etc. Suitable for heavier conditions due to
better protection against foreign matters. It is used with the
Y bearings (standard).
