The WBS is a single-action rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (WBS) on the side facing away from the medium, against dirt accumulation from the outside. Tight and accurate fitting is achieved by the metal outer surface. The WB model has limited sealing action with thin fluid or gaseous media and with split housings. To guarantee a high degree of static sealing on the outer surface, better surface treatment of the housing bore is required or an additional coat of paint should be applied to the outer surface.
Suitable tools should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support.
Sealing of rotating machine elements such as shafts, hubs and axles.
