WBO

PRODUCT DESCRIPTION

The WBO is a single-action rotary shaft seal for rotating or pivoting shafts. The sealing lip design without a spring produces less friction. As a result, the sealing action in comparison to rotary shaft seals with energised springs is reduced. Tight and accurate fitting is achieved by the metal outer casing. The WBO model has limited sealing action with thin fluid or gaseous media and in split housings. To guarantee a high level of static sealing on the outer surface, better surface treatment of the housing bore is necessary.
