A drive sheave of an elevator for use with a coated steel cord comprises a metal body and separators. The metal body has shallow circumferential grooves with a groove depth. The grooves are separated from one another with separators that extend out of the metal body much more than the groove depth. The separators are made of or are provided with a low friction coating. The friction coefficient between the separators and the coating of the coated steel cord is much lower than the friction coefficient between the metal body and the coating of the steel cord. The metal body can be assemble out of discs each having a single groove. The friction force of the coated steel cord can further be influenced by making the groove width less than the diameter of the coated steel cord. An elevator comprising coated steel cords running over the sheave is also claimed.
