A b s t r a c t. The results of tribolic properties of non-metal materials hard wood (beech), Teflon, Werkstoff “S", Alkamid are introduced in the study. The obtained experimental values reached on a tribometer with shift movement reveal the excellent sliding properties of Werkstoff 'S" material at low wear. This material is of exceptional health characteristics and makes possible recycling of the waste which develops during chip working. Shearing friction coefficient is comparable with that of Teflon.
