A linear actuator includes a hollow housing that is formed from a first portion and a second portion. The first portion of the housing is formed to support all of the components of the linear actuator therein, while the second portion of the housing functions to retain such components in the first portion of the housing. An end cap is secured to the end of the elongated tube portion to close the housing. The linear actuator includes a motor that operates through a clutch assembly to selectively rotate a screw. The clutch assembly limits the amount of torque that can be transmitted from the motor to the screw assembly. A nut is mounted on the screw assembly for linear movement in response to rotation of the screw assembly. An extension tube is crimped onto the nut for effecting linear movement of a workpiece. The structure of the nut is designed to facilitate an improved crimping connection between the nut and the extension tube. A dynamic braking circuit is provided to minimize coasting movement of the nut and the extension tube after motor has been turned off.
