Comparison of tribolic properties of selected non metal materials suitable for production of the carirer plates for bulk conveyers (a short communication)

The results of tribolic properties of non-metal materials hard wood (beech), Teflon, Werk-stoff'S", Alkamid are introduced in the study. The obtained experimental values reached on a tribometer with shift movement reveal the excellent sliding properties of Werk-stoff'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.
