Stieber has been one of the world's leading manufacturers of precision freewheels, indexing clutches and backstops for more than 75 years. Its extensive product portfolio ranges from compact units for light-duty machinery to heavy-duty solutions capable of transmitting extremely high torque in demanding industrial applications. Stieber products are widely used in conveyors, packaging machines, machine tools, pumps, gearboxes and bulk material handling systems where reliable one-way torque transmission is essential.

Freewheels operate by allowing relative rotation between the inner and outer rings in one direction while automatically locking in the opposite direction. Depending on the application, they can function as overrunning clutches, indexing clutches or backstops, preventing reverse rotation or enabling precise intermittent motion. Stieber offers both roller-type and sprag-type technologies, allowing engineers to select the optimum solution for torque, speed and operating conditions.

The product range covers torque capacities from 2.1 Nm to 287,500 Nm and shaft diameters from Ø6 mm to Ø300 mm, making Stieber suitable for virtually every industrial drive application. As the official Hungarian partner, BIBUS Kft. provides engineering support for product selection, sizing and integration into new or existing drive systems.
