Abstract
The invention relates to a linear actuator (), at least including a stator () that is placed within a cartridge-like casing (), a bearing ring () with a bearing seat for mounting a rotor () with an antifriction bearing (), a spindle () that on its drive side () is together with the rotor () designed as motion transformer to transform the rotary motion into a translatory motion and a flange () that closes the casing () on the output side () of the linear actuator (), the flange () being equipped with an anti-rotation locking device for the spindle output side () that penetrates the flange (). According to the invention the cartridge-like casing () is provided with several formed bending tongues (), whereby in assembled condition first bending tongues () engage with groove-like recesses () of the bearing ring () of the antifriction bearing () and second bending tongues () engage with groove-like recesses () of the flange () so that all components (and) placed in the casing are tensioned against each other without further connection techniques being required.
