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 ELSZ is a carriage driven actuator with single fixed belt. They come with either a standard width belt, or a wide belt for greater capacity.

ELSZ Actuators are available in multiple configurations;

• Standard Length Carriage
• Standard Length Wrap Around Carriage (WAC)
• Extended Length Carriages
• Extended Length Wrap Around Carriage (WAC)
