ABSTRACT OF THE DISCLOSURE A sheave for guiding and supporting stranded wire rope. The sheave includes a plurality of circumfer- ential grooves, with treaded elastomeric inserts being disposed in the grooves. The walls which define the treads are disposed at a predetermined angle relative to the circumferential axis of the insert, selected such that they will be substantially perpendicular to the longitud- inal axis of a strand, as each strand of the wire rope contacts and extends across a tread. The treads are thus fully compliant with the incremental changes in strand length due to the differential in rope tension on the two sides of the sheave.
