FGA21 Slewing Drive
Enclosed hourglass-worm slewing drives with cup seal. The same helical gear and hourglass-worm design as the FGE Series, but the face is sealed with a cup seal instead of a lip seal for a better sealing arrangement, up to IP65. Self-locking gearset, multiple accuracy levels, metric or inch mounting.
