LINEAR ACTUATOR

A linear actuator includes an actuator body including a housing, a gear set mounted inside the housing, a drive unit mounted outside the housing for rotating the gear set, a transmission mechanism including a lead screw with an axial rod at one end thereof fastened to the gear set, a stopper component set fastened to a neck of the axial rod, two bearing housings mounted on the axial rod at two opposite ends of the neck and two thrust bearings respectively mounted in the bearing housings. When the lead screw is rotated, a first stopper block of the stopper component set is engaged with the neck of the axial rod to force the stopper component set against the thrust bearings, enabling the linear actuator to carry greater axial thrust or tensile load, increasing the high impact load strength of the linear actuator and ensuring overall structural stability and reliability.
