In this study, factors analysis is performed for reducing friction in elevation motion of a large television stand over 50-inch. The first is a pipe type cross-section control for accurate position control of the piston rod. Here, it was compared with the pipe type and labyrinth type orifice cross-section. The second study attempted to reduce the frictional force the gas seal lip technology. As the result of the first study, in the orifice cross section study between pipe type and labyrinth type through CAE and experimental consideration, cross section of labyrinth type orifice is preferred for reducing of friction. As the result of the second study, in the gas seal lip technology, the outer-inner diameter of φ20×φ8 in the test result of hollow rod is revealed more proper if the weight of 50 inch television assumed as 30kgf.
