Abstract
An illustrative example embodiment of an elevator sheave liner includes a liner body having an inner surface configured to be received against a sheave and an outer surface configured to engage an elevator tension member. The liner body comprises a polymer material and a plurality of wear resistance particles in the composite material. The wear resistance particles are nanoparticles or microparticles. At least some of the wear resistance particles establish a traction characteristic of the outer surface of the sheave liner.
