Abstract

A roll line unit for a continuous casting apparatus includes a roll mantle or roll body surface rotatable relative to a support housing by means of bearing(s). The support housing has a seal(s) located axially outward relative to the at least one bearing and/or seal(s) located axially inward relative to the at least one bearing, and a lubrication system having lubricant reservoir(s) containing lubricant. The support housing has one or more cavities containing lubricant located adjacent to the seal disposed axially outward of the bearing(s) and/or the seal located axially inward of the bearing(s). The lubricant reservoir(s) is/are in fluid communication with the at least one cavity. An actuator within the lubricant reservoir(s) is arranged to move when the volume of lubricant increases in the cavity and/or the reservoir, and/or to push lubricant from the lubricant reservoir into the cavity when the amount of lubricant in the cavity decreases.
