Abstract: Pressed shape steel, made of a low cost general steel material that is not hardened, forms a frame with long grooves cut therein.

Because the general steel material and the specialized steel material are principally ferrous materials, both exhibiting a Young's modulus at or above 170 GPa with substantially the same coefficient of linear thermal expansion, the frame needn't be increased in size or have a complex internal structure to reinforce the strength of the frame, and the guide rails remain securely retained in the grooves even if the actuator experiences changes in temperature.
