GEARBOXES
Gearboxes for electric motors are devices that are used to transfer and change the torque between the drive and the driven device. We can supply gearboxes made by SIEMENS, Bonfiglioli, NORD, SEW – EURODRIVE, HYDRO-MEC, Tramec.
Precise and powerful drive systems for optimum flexibility.
Our extensive range of gearboxes ensures that you will find the optimum product for your needs. We offer either stand-alone gearboxes or compact motor and gearbox designs called electric gearboxes.
Depending on the type of design, size and gear ratio, the gearbox provides higher or lower engine speeds. Therefore, the resulting ratio between input and output speed is one of the most important parameters. Our company can supply gearboxes designed for every industry sector. Types….
Electric Gearboxes
These consist of an electric motor integrated with the gearbox (the first gear is directly on the motor’s output shaft) or a separate gearbox for connection to a standard design engine (IEC) or other powertrain.
Output torques up to 20,000 Nm / 55 kW of engine power.
Industrial Gearboxes
These are high-quality gearboxes for demanding industrial applications up to 2,600,000 Nm. There are no end of solutions developed specifically according to the requirements of specific applications, such as various types of conveyors, mixers, and cooling towers.

Simogear spur gearboxes
Spur gearboxes are the most widely used gearbox design for all types of standard applications with a solid output shaft in the motor axis.
Key features:
- available for motor power up to 200 kW
- output speeds of 0.06 to 1,088 rpm
- output torque up to 20,000 Nm
- simple and robust design delivering high efficiency
- broad gearbox and motor configuration options
- also available in a version for zones where there is a risk of explosion or ignition (ATEX certification)
- design only with a solid output shaft
Simogear Shaft-mounted helical gearboxes
Gearboxes derived from the spur gearboxes, with an output shaft parallel to the motor axis. Suitable for applications where a spur gearbox would be too long, or where a hollow output shaft or a cylindrical one- or two-sided shaft is required.
Key features:
- available for motor power up to 200 kW
- output speeds of 0.05 to 365 rpm
- output torque up to 20,000 Nm
- simple and robust design delivering high efficiency
- broad gearbox and motor configuration options
- also available in a version for zones where there is a risk of explosion (ATEX certification)
- design only with a hollow or solid one- or two-sided output shaft
Simogear Helical-bevel gearboxes
Gearboxes with a combination of spur and bevel gears are very popular due to their very high efficiency. They are suitable for applications that require a hollow or solid (one-sided or two-sided) output shaft perpendicular to the motor axis.
Key features:
- available for motor power up to 200 kW
- output speeds of 0.05 to 306 rpm
- output torque up to 2,000 Nm
- robust design delivering very high efficiency
- broad gearbox and motor configuration options
- also available in a version for zones where there is a risk of explosion (ATEX certification)
- design only with a hollow or solid one- or two-sided output shaft
worm gearboxes
One of the most widespread gearbox designs uses worm gears. The advantages of worm gearboxes are their low cost, very simple design and, where required, self-locking. Their downside is the relatively high torque loss (low efficiency).
Compact worm gearboxes are only supplied with a limited range of outputs and gear ratios. They are suitable for applications that require a hollow or solid (one-sided or two-sided) output shaft perpendicular to the motor axis. For more demanding applications and high output, we recommend Cavex worm gearboxes.
Key features:
- available for motor power up to 1.5 kW
- output speeds of 14 to 201 rpm
- output torque up to 224 Nm
- broad motor configuration options, limited gearbox configuration options
- design only with a hollow or solid one-sided or two-sided output shaft
Simogear Helical-worm gearboxes
Gearboxes combining spur and worm gears are cost-effective and torque-resistant. The main disadvantages, compared to the helical-bevel design, are the lower efficiency and smaller range of outputs and gear ratios. They are suitable for applications that require a hollow or solid (one-sided or two-sided) output shaft perpendicular to the motor axis.
Key features:
- available for motor power up to 9.2 kW
- output speeds of 0.05 to 148 rpm
- output torque up to 1,590 Nm
- broad gearbox and motor configuration options
- also available in a version for zones where there is a risk of explosion (ATEX certification)
- design only with a hollow or solid one-sided or two-sided output shaft

- gear ratios of 25 to 4,000
- output torque up to 2,600,000 Nm
