R&B Plastics manufactures high quality, precision custom plastic sheaves for a range of industries, specializing in the material handling, construction, transportation, recreational, and sporting goods industries. Our machined plastic sheaves have earned the reputation for their high quality and durability in high wear, demanding applications.

Plastic sheaves are grooved wheels used to control ropes, chains, wire rope, cables, flexible hose, and belts. They are used in lifting and mechanical equipment, where their strength, light weight, elasticity, and resistance to wear and corrosion provide superior performance when compared to steel or cast iron sheaves. The use of plastic materials reduces the wear on the rope, wire, chain, or cable when compared to metal sheaves, extending the life of the rope or cable equipment.

R&B Plastics’ custom sheaves are used in cranes, lifts, forklifts, manlifts, winches, conveyors, and other equipment requiring wire, cable, rope, hose, or belts. Our staff will work with you to manufacture a plastic sheave customized for your application that will meet or exceed your expectations.
