Patentanspruch:Claim:Drehbar gelagerter Körner für Werkzeugmaschinen, insbesondere Drehbänke,
bei dem am vorderen und hinteren Ende des Körnerschaftes Kugellager die axialen und seitlichen Drucke aufnehmen, dadurch
gekennzeichnet, daß das hintere Kugellager durch halbkugelförmige Ausbildung des
hinteren Endes (2a) des Körnerschaftes (2), das in eine teilweise mit Kugeln (10)
gefüllte Lagerschale (6) hineinragt, gleichzeitig als Achs- und Stützlager wirkt.Rotatably mounted grains for machine tools, in particular lathes, take up the axial and lateral pressures at the front and rear end of the grains shaft ball bearing, characterized in that the rear ball bearing by hemispherical design of the rear end (2 a) of the grains of the shank (2) protrudes into a bearing shell (6) partially filled with balls (10), at the same time acting as an axle and support bearing.
