Modular Linear Actuator, External Roller Bearing Guided, External Belt Driven, Model ELSD, Standard Belt, Wrap Around Carriage, 100

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 ELSD is a carriage driven actuator with single fixed belt and a center shaft extending through the actuator.
