Series R : Inline Helical Gearbox

Our SGR inline helical gearbox (series R) comes with a grade cast iron housing and high strength steel gears. You can use them with the SGR inline helical gear motors. These motors can be powered by either a DC or AC supply source. For safe operations, the SGR helical motors are flame proof with brake motor options.

As a premier inline helical gearbox & gear reducer manufacturer, we understand the convenience and efficiency an in-line transmission guarantees. All our inline helical gearboxes and motors are easy to maintain and replace.

With our helical gearbox you can attain a wide range of output torque (200 – 1800 Nm), ratio (3.33 – 287.74), mounting position (M1 – M6) and rating power (0.18 kW – 160 kW). We have a wide of inline helical gear motors/gearboxes to choose from.

SGR helical gear reducers and motors have a long service lifespan, smooth and low noise operation. Also, every SGR gearbox is subjected to heat treatment, thus they are rigid and durable.

Irrespective of the type of application, you can also benefit from our multi-position mounting of our inline helical gear box or inline gear motors.
