A sheave (/ʃiːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. A sheave (pronounced “shiv”) is actually part of the pulley system. The sheave is the rotating, grooved wheel inside the pulley.
