Applications
Tacolab seals can only be used for certain gear ratios and minimum speeds.
Features
Tacolab seals are non-contact, low-maintenance seals that do not wear. It is not therefore
necessary to interrupt operation in order to service or replace them.
The Tacolab seal is a combination of two sealing elements:
• Labyrinth seal comprising two labyrinth sealing rings to prevent the escape of lubricating
oil
• Grease-filled dust seal (comprising a labyrinth and a lamellar seal) to allow operation of
the gear unit in extremely dusty environments
