Abstract
An improved neck seal having an interior surface being concave throughout and shaped to entirely conform to the circumference of a roll surface of a roll. The concave surface further defines the interior side of an oil-side lip extending upwards from the seal body. A portion of the lips outermost end extends radially downward to form a first stop integral with the lip. A portion of the outermost end of the seal body also extends upward from the top surface thereof to form a second stop integral with the seal body. A v-shaped spring is then disposed in a v-groove defined by the inclined bottom surface of the oil-side lip, and the flat top surface of the seal body. In this manner, the first and second stop retain the spring in a position conducive for a more positive seal contact between the lip of the seal and the roll neck without the use of a garter spring.
