Rope sheaves guide and support wire ropes, cables and belts under continuous rotating and frictional contact. Metal sheaves generate greater surface friction, accelerate rope wear and are prone to corrosion in outdoor or humid environments. Engineering plastics such as POM-C and PA6C provide a smoother, lower-friction running surface that extends rope service life, while significantly reducing sheave weight.

Wear-resistant grades maintain dimensional stability under sustained mechanical load, resist groove deformation over repeated cycles, and require little to no lubrication in service. In corrosive or washdown environments, chemically resistant grades prevent the degradation that affects metal sheaves over time.

Plastix Factory supplies sheave stock as round bars and cut-to-size blanks, or as CNC-machined finished sheaves manufactured to your groove profile, bore and load specifications.
