A rolling mill stand relies on this conical seal to keep coolant and scale away from the bearing assembly. In the steel industry the seal is fitted between the roll neck and its housing where it forms a static barrier that withstands the intense heat generated during hot rolling. By preventing the escape of lubricating oil and the entry of water‑based cooling spray, it maintains a clean, dry environment around the bearings and reduces wear on the roll surfaces. The seal also absorbs small axial movements caused by thermal expansion, helping to preserve the precise roll gap that determines sheet thickness and surface quality. Because the conical shape distributes contact pressure evenly, the seal resists extrusion even under the high radial forces present in continuous‑casting mills and reheating furnaces. Operators notice fewer unscheduled stops for bearing cleaning and longer intervals between seal replacements, which translates to higher mill availability. A similar application exists in metal‑forming presses where the same conical seal protects hydraulic rams from contaminants, ensuring consistent force delivery during stamping operations.
