Series K : Helical Bevel Gearbox

SGR helical bevel gearbox (series K) is unique for its right angle transmission. When coupled to a helical gear motor, it will guarantee optimal performance even in multi-position mounting applications.

With the modular designs, the SGR helical bevel gearboxes, can be customized depending on clients’ needs. For all our helical bevel gear reducers, the casing is mainly cast iron, while both gears and axis are made from high quality alloy steel.

As an experienced helical bevel gearbox & gear reducer manufacturer, we subjected every part to heat treatment. This ensures every helical gearbox and helical gear motor is strong, rigid and durable.

Also, our bevel helical gearbox has additional gear reducers. These help to achieve the required gear reduction ratio and variation.

Moreover, depending on the type of task and helical bevel gearbox reducer, you may opt for either a single or three phase motor. The SGR motors may use either DC or AC supply.

In short, SGR is a high torque speed reducer manufacturer that supplies quality and reliable helical bevel gearboxes for a wide of tasks.
