The self-aligning roller bearing has inner and outer bearing rings and rollers arranged at least in one roller row. The rollers have a curved lateral surface the direction of the rotation axis and has a radius, and roll over curved raceways of the bearing rings. The raceways are each assigned a groove point around which the curved raceway extends at a radial distance in the direction of the rotation axis. A pressure line intersects the rotation axis at an angle of 90° at a point where these rollers have their largest roller diameter, and the radius of the curved lateral surface is smaller than both radial distances.

Abstract: A rolling bearing has an inner and an outer bearing ring. Each bearing ring has an inner and an outer shell surface. The roller bearing has rolling elements, which roll on raceways provided on the respective shell surfaces of the bearing rings, and a sealing disc connected to one of the bearing rings and operatively connected in a sealing manner to the other bearing ring. To connect the sealing disc to the bearing ring, one of the shell surfaces of the one bearing ring includes a first connecting means and the sealing disc includes a second connecting means. The first connecting means provide a rotating engagement in which the second connecting means engage in a connected state of the bearing ring and the sealing disc.

Abstract: The invention relates to a pin-cage, for a twin-row self-aligning roller bearing, essentially comprising an inner ring, an outer ring and several rollers, running adjacently between the above, in two rows on the running tracks of the inner ring and the outer ring. A pin cage is arranged between the roller rows embodied with pins on the axial faces thereof at even spaces with a stepped offset. The rollers of both roller rows each comprise an axial through drilling, by means of which the above are rotatably mounted on the pins of the pin-cage. According to the invention, the pin-cage is embodied as a pre-assembled component without a lateral disc and pins feely extending axially from the above, the length of which is less than the length of the through drillings in the rollers, whereby lubrication of the rollers is achieved by centrifugal force from the free front face thereof through the outer opening of the through drilling thereof.
