Industrial gearboxes

A gearbox is an essential component in the world of mechanics.

Gearboxes are mechanical gear transmissions that transmit the movement of a motor to the machine to which they are applied, reducing the speed in order to adapt it to operating requirements. By reducing speed, the gearbox multiplies torque.

CORDM proposes different types of gearbox: planetary gearboxes (offering a high reduction ratio with small space requirement), parallel shaft or gear train gearboxes (for applications requiring high power) and angular gearboxes (capable of handling high power), all in strict compliance with your requirements and specifications.

We look forward to hearing from you. Our sales teams are at your disposal.

Looking for more information about mechanical reducers?

To choose the right mechanical speed reducer, it’s important to consider several key criteria, such as the reducer’s dimensions, reduction ratio, and output torque.

There are also different types of mechanical reducers, each with their own characteristics: parallel shaft reducers, planetary gear reducers, and bevel gear reducers. In addition, some reducers are integrated with a motor, these are known as motor reducers.

As a true specialist in the calculation and manufacturing of gears and mechanical reducers for nearly 40 years, CORDM offers a wide range of mechanical reduction systems, including planetary reducers, gear trains, angle drive reducers, and more.

Explore all of CORDM’s additional services as well: gear calculation, gear manufacturing (bevel, planetary, helical, or rack-and-pinion), precision machining, and gear and pinion grinding for all types of tooth profiles.

Custom mechanical gearbox design: CORDM’s solution for demanding industrial applications

In industrial environments, every setting comes with its own challenges. Confined spaces, extreme temperatures, fluctuating loads, humidity, or dust: conditions that very few standard gearboxes can withstand over time. This is why at CORDM, each mechanical gearbox is engineered as a custom solution, designed to suit your real operating conditions.

A mechanical gear reducer is not a generic component. It is the core of the power transmission system, ensuring optimal torque conversion and reliable motion control. When properly engineered, it reduces speed, increases torque, and protects the entire kinematic chain. Every gear reducer we manufacture is precisely sized to meet your load requirements, duty cycles, and integration constraints, whether for a special-purpose machine or a production-series system.

Our expertise covers the full process: from load calculation and gearbox sizing, to defining the right type of mechanical reducer, selecting materials, and performing the appropriate heat treatment on critical components. Thanks to our in-house design office, we deliver mechanical speed reducers perfectly tailored to your needs: parallel-shaft gearboxes, planetary gear systems, bevel gear reducers, or combined configurations. The goal is always the same: reliability, compactness, and performance.

Our ability to manufacture all mechanical gearbox components in-house : shafts, housings, gears… gives us exceptional flexibility.. We can precisely adjust gear ratios, tooth profiles, and reducer geometry to meet your technical specifications. This mastery guarantees quiet operation, extended component life, and improved energy efficiency.

At CORDM, producing a gearbox reducer is more than machining parts: it is a matter of expertise, engineering insight, and a commitment to delivering the most suitable solution. For every machine, every environment, and every application, there is a mechanical reducer perfectly dimensioned, and we design it with you.
