In recent years, the development of high strength gel has progressed, and it is entering the stage of trying to apply it to mechanical parts making full use of the low friction property of gel. If this is realized, further increase in energy efficiency is expected. DN gel has high strength and low friction. We are aiming at practical application as P type O-ring utilizing this performance. In this study, a vertical rotation type testing machine was introduced, and friction measurement was performed under conditions assuming helical motion.
