Zusammenfassung:	Disclosed is a system comprising a traction sheave (210) and a liner (200), the liner (200) comprising: a top surface and a bottom surface (230) mutually spaced on a height-wise axis (H), a front surface and a back surface mutually spaced on lengthwise axis (L), and a plurality of side surfaces including a first side surface and a second side surface mutually spaced in a widthwise axis (W); wherein a first cross sectional profile of the plurality of side surfaces forms a convergent-divergent profile; wherein the bottom surface (230) of the liner (200) includes a first groove (280) extending height-wise upwardly; and wherein the traction sheave (210) comprises a cavity having a same height-wise span as the liner, the cavity comprising a plurality of side surfaces having a second profile that is complementary to the first profile wherein the liner (200) comprises a nominal clearance fit when seated within the cavity.
