Device for arrangement of roller in hot-dip coating system, particularly metal coating system or galvanizing plant, has unit for arranging ventilation unit at front side of roller pins on side of roller

摘要

The device has a unit (7) for arranging ventilation unit (8) at front side of roller pins (3) on a side of a roller (1). The ventilation unit has a hollow space (9). The ventilation units produces the side of the roller in axial symmetrically arranged sealing surface (10) such that a bore hole (4) of the roller pin has a contact with the hollow space of the ventilation unit within the sealing surface.
