Which Gearbox Type Do I Need?
A worm gearbox is usually chosen for compact right-angle speed reduction, especially where space is limited and a simple industrial gear reducer is required. Worm gearboxes are common on conveyors, packaging machines, small mixers and general machinery.
An inline helical gearbox is best when the motor and output shaft need to stay in line. These gearboxes are efficient, smooth running and suited to conveyors, rollers, production lines and automation systems.
A helical bevel gearbox is used when you need a right-angle gearbox with higher efficiency and stronger continuous-duty performance. These are often selected for heavier industrial applications, handling systems, mixers and OEM machinery.
A mechanical variator is ideal where simple adjustable output speed is required without using an electronic inverter drive. Variators are commonly used on conveyors, packaging machinery, mixers and industrial equipment where manual or mechanical speed control is needed.
Common Gearbox Applications
- Conveyor systems and roller conveyors
- Packaging machinery and production lines
- Food processing equipment
- Mixers, agitators and rotating equipment
- Material handling systems

Gearbox FAQs
What is an industrial gearbox?
An industrial gearbox is a mechanical drive unit used to reduce motor speed and increase torque. Gearboxes are commonly used in conveyors, packaging machinery, mixers, production equipment and automation systems.
Which gearbox type should I choose?
Choose a worm gearbox for compact right-angle reduction, an inline gearbox for straight-through drive layouts, a helical bevel gearbox for efficient right-angle power transmission, or a variator when adjustable mechanical speed control is required.
What is a mechanical variator?
A mechanical variator is a speed adjustment unit used to vary output speed mechanically. It is often used in drive systems where simple speed control is needed without an electronic inverter drive.
Can gearboxes be fitted with IEC motors?
Yes. Many industrial gearboxes and variators can be supplied with IEC motor input options, making them suitable for pairing with standard AC electric motors.
How do I choose the right gearbox ratio?
Start with your motor speed and required output speed. The gearbox ratio determines how much the motor speed is reduced and how much torque is increased.
Can you help replace an existing gearbox or variator?
Yes. Send us the gearbox or variator model, ratio, motor power, mounting position, output shaft details and any nameplate photos, and we will help identify the closest replacement option.
Do you offer gearbox selection help?
Yes. If you are unsure which gearbox or variator you need, contact us with your application details and we will help select the correct type, size, ratio and motor input.
