FWA25 Slewing Drive
Full-throat worm slewing drives with cup seal. A full-throat worm with the face sealed by a cup seal instead of a lip seal, for a better sealing arrangement up to IP65 against dust and water. Single or double worm (double the torque), self-locking or non-self-locking, metric or inch mounting.
