Conveyor rollers

Interroll offers a broad range of conveyor rollers that cover nearly all processes in the area of internal logistics, from bulk materials handling to transportation of storage units such as containers and pallets.



The Interroll RollerDrive is a DC brushless motor integrated in a conveyor roller, which can be employed in the most diverse conveyor systems.

The motorized roller has specifically been tailored to the needs of intralogistics users. It is very energy efficient and can be easily integrated into the applications.


Magnetic Speed Controller MSC 50

With the MSC 50 magnetic speed controller, Interroll launched another innovation in the spring of 2016, which intelligently regulates the speed of sloped conveyors, preventing damage to the material being carried.
