VHX Series Gearboxes

VHX Series gearboxes are vertically-oriented, heavy-duty drives built for the most demanding industrial applications. Designed with a split-plane housing and maintenance-free sealing system, these gearboxes ensure reliable operation and easy servicing even under high overhung loads.

With up to 1100 kNm output torque and 20 size variants, VHX drives feature helical and bevel helical gears, robust shaft support, and powerful gear geometry to reduce vibration and noise. Optimized for vertical use, the housing includes symmetric mounting feet and pump-based lubrication, making them ideal for cooling towers, mixers, toasters, and pulpers.
