That would most likely be a pulley. A pulley is essentially a wheel on an axle that usually has a groove in the middle of its circumference that holds a rope, cable, belt, or chain. Pulleys are used to transmit motion rotationally and apply force in the direction of said motion. Two or more pulleys makes a tackle. Hope this is what you were looking for.
A bezel is a grooved ring that holds a watch crystal in place. A lip encircles and overlaps the crystal, holding it in place.
