bearing cartridge 3 in such a way that a uniform oil film 19 is formed in the interspace 17 between the bearing cartridge 3 and the inner wall of the bearing housing 5 the interspace 17 is of such width in the present case that the oil film 19 enables an adequate thickness for vibration insulation between the outer cartridge ring 9 and the bearing housing 5 overall by using the anti friction bearing 7 a lower friction moment is transmitted than in the case of a plain bearing so that a separate anti rotation device can be dispensed with furthermore the outer bearing ring 9 is provided with an oil drainage groove 29 on its outer circumference via which the oil of the oil film 19 can drain off in the installed state of the bearing 7 the oil drainage groove 29 is connected in a communicating manner to an oil drainage hole 31 the diameter of which is dimensioned so that a problem free drainage of oil is ensured in this way a constant oil film 19 can be ensured in addition the oil also drains off in the axial direction outwardly between the outer bearing ring 9 and the bearing housing 5 in addition the oil is pushed from the grooves 25 27 in the outer bearing ring 9 into the bearing interior 37 via two splash oil holes.
