1 ELA Electromechanical Linear Actuators D

2 Electromechanical Linear Actuators ELA Electromechanical Linear Actuators (ELA) consist of a completely enclosed aluminium housing with worm gearing and axial bearing driven by a standard supplied electric motor as well as a thrust and shaft tube construction. Trapezoidal or ball screws. It is possible to install ELAs in any position and the thrust and guide mechanism is designed for both compressive and tensile loading. Other distinguishing features include robust construction and reliability giving ELAs a wide range of applications.
