The present invention relates to a low-friction tapered roller bearings (1), with two mutually coaxial bearing rings (2, 4) as well as a plurality of between said bearing rings (2, 4) arranged, in a cage (9) of tapered rollers (7) is guided on associated raceways (3, 5) of the bearing rings (2, 4), and with at least one board (6) to one of the bearing rings (2, 4) to the discharge of axial forces from the tapered roller bearings (7). As large as possible a reduction of the inner friction of the tapered roller bearing (1) can be achieved, according to the invention, the pressure angle (dW) of the tapered roller bearing (1) ≧ 32°, that the cone rollers angle (rW) ≥ 9°, and of the ratio value of the cone rollers length (lr) to the diameter (dr) of the large end face (8) of the tapered roller bearings (7) lr / dr ≦ 1,8 is.
