Modular Linear Actuator, External Roller Bearing Guided, External Belt Driven, Model ELZU, 30

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 ELZU consisting of two Y-axes and single X-axis, driven by one rotating belt. This belt runs around different deflection pulleys. Positioning is achieved by two motors. The coordinate is diagonal to the deflection points of the Y-axis. Advantage: A smaller amount of inertia is needed, thus enabling high accelerations to be achieved.
