Mechanical Assembly: Linear Screw Jack / Actuator Assembly Central Gearbox Housing: A rectangular block gearbox body with chamfered vertical edges. Top face features a circular flange plate held by a ring of 6 evenly spaced bolt holes, housing a bearing pocket and central bore. Right side face features a smaller cylindrical input shaft extension housing with a 4-bolt square flange, containing an input drive shaft extending outward with a keyway. Vertical Lead Screw / Trapezoidal Threaded Rod: A long, vertical threaded shaft extending upward from the top circular flange. The top end terminates with a spherical rod end bearing (rod eye connector) featuring a through-hole for mounting. Lower Protective Tube / Cylinder: A smooth, cylindrical protection tube extending vertically downward from the bottom face of the main gearbox housing, aligned coaxially with the lead screw.
