A method for manufacturing a linear actuator includes inserting a portion of a thrust member of the actuator into a casting portion of a molding apparatus. The casting portion includes a model screw member having a threaded portion. A molding material can be added into the cast portion to overmold a nut to the thrust member. Thus, the nut will include a threaded portion on an internal circumference mateable with the threaded portion of the model screw member. The overmolded nut and thrust tube member may be coupled to a screw shaft of the actuator, such that the threaded portion of the nut mates with a threaded portion of the screw shaft.

Method for manufacturing a linear actuator

An electrically powered linear actuator having a thrust assembly, a motor with a hollow rotor surrounding at least a portion of the thrust assembly, and a lubricant passage for replenishing lubricant to the force transmitting components of the actuator.
