System for a non-positive connection between shaft and roller ring.

The “FSE” is a “mobile control unit” designed to meet the needs of the steel industry. The system is used to press rolling rings on and off. The high-pressure control unit generates the hydraulic pressure required for the mounting and dismounting process. These processes are monitored by a modern controller; the program sequence as well as all pressure and time values ​​are optimally set at the factory. All important parameters can be adjusted using the built-in manual input device (HMI).

Areas of Application

The SCHAAF FSE has proven itself exclusively in steel works, namely in the rolling mill. There, the hot raw material is pushed through stands with rolling rollers until the desired material thickness is reached. Depending on the type of material required or if the rollers used are too worn, new or different roller rings are required. This is where the FSE is used in combination with the A-LOC tool.

Quality Assurance

All FSE are checked for 100 % process security. During order handling, they are accompanied by ongoing quality assurance measures and supplied
with extensive documentation.




SCHAAF FSE are user-friendly, reliable, and manufactured in accordance with the highest level of technical know-how. Our highly-motivated staff would be pleased to train your personnel, in situ or at our works, in the general handling and operation of the mobile and stationary control unit. In this way, all the process parameters can be entered optimally in order to achieve maximum process monitoring and safety. Of course, the FSE are supplied ready for operation.
