Modular Linear Actuator, External Roller Bearing Guided, External Belt Driven, Model ELFZ, 80S

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 ELFZ is a carriage driven actuator with single fixed belt. Beacuase the single belt wraps around with both ends and is fixed to the carriage, a larger capacity can be realized.
