Industrial Helical Gearboxes

Continuous-duty helical gearboxes for conveyors, mixers, fans and process drives — specified against your torque, ratio and mounting requirements before we propose a cross-reference.

How we supply gearboxes

We don't manufacture under our own brand. We source gearboxes from qualified manufacturers matched to your spec, and where nothing off-the-shelf fits, our engineering team can reverse-engineer from a sample or worn part, or build to your drawing through our manufacturing partner network — see OEM Services.

Technical description

Helical gearboxes use parallel-axis helical gear stages to transmit power with high efficiency and low noise, suited to continuous industrial duty. We specify unit size, ratio and mounting configuration against your input speed, output torque, service factor and ambient conditions, then match the requirement to whichever qualified manufacturer in our network fits best — or reverse-engineer/custom-build one if nothing off-the-shelf does.

Applications

01

Belt Conveyors

Continuous-duty drive for bulk material handling lines.

02

Mixers & Agitators

High-torque, shock-tolerant drive for process vessels.

03

Fans & Blowers

Stable-speed drive for ventilation and process air systems.

04

Bucket Elevators

Shock-load duty for vertical material transport.

Advantages

High efficiency

Helical gear stages minimize transmission losses versus worm designs.

Low noise operation

Suited to enclosed or personnel-adjacent installations.

Modular mounting

Foot, flange and shaft-mounted configurations available.

Documented QA

Inspection and test records issued with every shipment.
