Z 309, SKF, Sealing washer, standard design

The standard sealing washers are intended for normal operating conditions, e.g. for conveyor rollers and various types of pulleys.

A set of standard design sealing washers comprises one shaft and one housing washer. The washers are made of sheet steel, and are phosphated and coated with a preservative. The outside diameter of the housing washer and the bore of the shaft washer are slightly tapered so that the washers will have a tight fit after mounting.

The sealing washers are able to accommodate axial forces to a certain extent and are therefore also suitable as spacer sleeves for applications where an exact axial location of the adjacent components is not necessary.
