Flat gear is a gear with high power density and high torque. The gear has a special construction shape formed from the pinion gear. However, the output shaft is offset from the motor shaft, which makes it possible to make a hollow shaft.

The advantages of this type of gear are high efficiency, low noise level and friction torque.

We sell flat gearboxes from German ABM Greiffenberger and ebm-papst Zeitlauf as well as Swiss Portescap. These suppliers are one of the world leaders in motors, gears, and controls and have an extensive range of products.

The gears offer strong performance with torque up to 2300 Nm, and are available in a wide range of ratios with standard or customized shafts. In addition, the gears are efficient with a compact design, and are flexible as they can be supplied with different motors and brakes according to size and conditions. Some flat gear units can also be supplied with NEMA flange in different sizes.

We are happy to put together the flat gear with the electric motor and accessories needed for your project.
