Inline Helical Speed Reducers

Precise engineering for efficiency and power.

Vortex Inline Helical Speed Reducers combine case hardened steel materials with precision grinding to give you more horsepower with less vibration, creating efficiency and power in a variety of applications. Our large local inventory means our reducers are ready to get you up and running quickly, so you can get back to work.

We’ve designed each Vortex Inline Helical Speed Reducer with:


Ground Gearing to reduce heat and friction inside the gearbox for quiet running, durable power.

Pressure Tested Seals to ensure that every unit is leak-free when it leaves our factory.

Centerless Ground Bearing Seats for perfect bearing fit and peak performance.

Cast Iron Housing to withstand the vibration and shock of any application.

Corrosion Resistant Finish to endure even the toughest environments.

NEMA C Flanges to allow easy integration with off-the-shelf electric motors.

What can you expect from Vortex Shaft Mount Speed Reducers?

Minimal oil leakage and longer seal life.

Our metal-reinforced, spring-loaded, double-lip oil seals ride on shafts with ground seal seats minimizing oil leakage and providing longer seal life.

High strength shaft with ground bearing seats for longer bearing life.

Our one-piece shafts are made of heat-treated alloy steel for high strength. We use centerless ground bearing seats to provide ideal shaft fit and extend bearing life.

Protection from wear and corrosion.

Vortex reducers use cast iron housings and feature a highly corrosion-resistant finish to dampen the effects of vibration and shock, protect from corrosive elements, and provide ideal lubrication throughout the life of the unit.


We use a Cast Iron NEMA C input flange, making our reducers compatible with most off-the-shelf electric motors.
