Overview

ACTUATORS: STRONG POSITION CONTROL FOR EVERY DEMAND

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.

BST Electromechanical Actuators at a Glance

• Low-wear direct current motors
• Ball screw actuators, for high durability and minimal play
• Designed for arc-shaped and linear positioning motions
• Various sizes possible for positioning distance, positioning strength, and positioning speed
• Electromechanical BST actuators have a position feedback (precise recording of the current position of the actuator) and electronic end position switch-off
• Maintenance-free

EMS 18

The BST EMS 18 actuator has a stroke of up to 200 mm with a positioning force of up to 840 N. Various combinations of stroke, positioning force, and speed are possible.

EMS 21

A stroke of up to 195 mm with a positioning force of up to 1,680 N – that is the performance of the BST EMS 21 actuator. Various combinations of hub, positioning force, and positioning speed are possible here as well.

EMS 22

The BST EMS 22 actuator is powerful, with a stroke of up to 195 mm with a positioning force of up to 2,250 N. This product was specially designed for use on winder controls and is also available in various designs.

EMS 23

The BST EMS 23 actuator impresses customers with a stroke of up to 300 mm at a positioning force of up to 9,000 N. It is also best suited for implementation on winder controls. The performance values for stroke, actuating power, and speed can be combined in the most diverse ways for an optimal application fit here, too.
