Series S: Helical Worm Gearbox

SGR helical worm gearbox (series S) has a torque output of 90 to 4,000 Nm with a power rating of 0.18 kW to 22 kW.  Like most of our gearboxes, the mounting position range between M1 to M6. This is yet, another highly efficient and robust SGR right angle helical worm gearbox.

Being a premier helical worm gearbox and gear unit manufacturer, we adhere to quality production process that conforms to DNV- ISO 900:2008, SGS and CE quality standards. The unique modular designs make all our gearboxes easy to maintain and replace.

Also, every helical worm gearbox can be coupled with a helical gear motor. For flexibility and convenience, you can choose either a DC or AC supply. Alternatively, you may also opt for the SGR single or three phase helical gear motor.

Like other SGR double helical gearboxes, we use cast iron to make the casing of both the gearbox and motors. While the gears and axis are made of high quality iron steel.

Since SGR is a reputable helical worm gear motor & speed reducer manufacturer, all our gears and motors are designed for smooth and quiet operations.
