• Rugged design with double reduction. First stage helical gears and second stage involute helicoid thread form worm gearing.
• Strength and power of worm gear plus the efficiency of a helical or spiral bevel gear.
• High capacity to sustain high starting loads or momentary shock overloads.
• Oversized output shaft and heavy-duty tapered roller bearings provides precise alignment and long dependable service.
• Dry-well dam around the output shaft provides a positive barrier against oil leakage and eliminates an output shaft oil seal.
• Motors are standard NEMA frame, flexibly coupled to the gearbox.
