The carriage is driven by an external linear belt that can be adjusted to reduce lash and is driven along the external roller bearings. The pulleys have maintenance-free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
The advantage of MLZ Actuator is that the belt is guided within the profile, ensuring that the belt is always tight and thus enabling the system to be operated when lying on its side. The pulleys have maintenance-free ball bearings.
