• Rugged Cast-Iron Housing: Provides maximum strength and dependability.
• High lead angle worm is case hardened, ground and polished.
• Large, Single Row Ball Bearings On Input Shaft: Absorb radial and thrust loads at higher input speeds. Tapered roller bearings are used on output shaft.
• Forged Bronze Worm Gears: Provide optimum balance of Strength and Wear.
