mittlung eines zischen der Dichtungsscheibe und einem mit der Achse a umlaufendem Widerlager oder Gehäuse eingeschalteten Stätzkugellagers gegen den äusseren Laufring gedrückt. Dadurch wird die Reibung zwischen Dichtungsscheibe und Widerlager wesentlich vermindert, so dass die Dichtungsscheibe sich infolge der zwischen ihr und dem Laufringe vorhandenen grösseren Reibung diesem gegenüber nicht dreht. Es wird also ein schädliches Schleifen zwischen Dichtungsscheibe und Gehäuse oder Lager verhindert. Da die Dichtungsscheibe von dem achsialen Druck fast völlig entlastet wird, so behält sie auch dauernd ihre für die Abdichtung wertvollen Eigenschaften.
Bei der Ausführung nach Fig. l sind die in einem Käfig n gefassten Kugeln 1 des Stütz- kugellagers in dem Hohlraum eines auf die Achse a aufgeschraubten Widerlagers oder Gehäuses (Verschlussmutter) h untergebracht. Der Käfig n ist durch einen Sprengring r am Herausfallen beim Abschrauben der. Mutter gehindert. Bei der Ausführung nach Fig. 2 besteht die Verschluss- mutter aus zwei Teilen, von denen der eine Teil h die Kugeln aufnimmt und lose auf der Achse o sitzt" während der andere Teil k mit der Achse verschraubt ist und den ersten Teil h gegen einen

by means of a hissing of the sealing washer and an abutment or housing rotating with the axis a pressed against the outer race. As a result, the friction between the sealing washer and the abutment is significantly reduced, so that the sealing washer does not rotate with respect to the running rings due to the greater friction between it and the raceways. This prevents harmful grinding between the sealing washer and the housing or bearing. Since the sealing washer is almost completely relieved of the axial pressure, it also permanently retains its properties which are valuable for sealing.
In the embodiment according to FIG. 1, the balls 1 of the supporting ball bearing held in a cage n are accommodated in the cavity of an abutment or housing (locking nut) h screwed onto the axis a. The cage n is by a snap ring r on falling out when unscrewing the. Mother prevented. In the embodiment according to FIG. 2, the locking nut consists of two parts, of which one part h receives the balls and sits loosely on the axis o "while the other part k is screwed to the axis and the first part h against one
