Between the sliding block walls (10, 17) of an attached sealing there is a porous-elastic sealing washer (19), closely enclosing the shaft, on the circumference of which washer is arranged an annular spring (20) which presses the sealing washer (19) radially onto the shaft circumference. Within the sliding block walls (10, 17), the sealing washer (19) can also seal the shaft (2) optimally when its longitudinal axis forms a limited angle with the bearing housing longitudinal axis (LGA). Despite the presence of such an angle, the sealing pressure of the sealing washer always remains the same all round the circumference of the shaft. <IMAGE> |
