BST actuators correct the position of the web precisely and almost instantaneously.

Electromechanical Actuators

Electromechanical actuators are used wherever very quick reactions to changes in the web position are necessary. The connection of the actuator can take place directly at the control unit. The ready-to-fit construction allows for quick and inexpensive installation, which is also beneficial in the retrofit of existing systems.

The BST actuators can be combined with our positioning devices for a number of web guiding tasks. We offer electromechanical actuators with a positioning force of up to 9,000 N and strokes up to 300 mm in designs with and without position feedback. The positioning forces of our hydraulic actuators reach up to 20,000 N with various strokes.
