Abstract
The invention concerns a large-size rolling bearing which is in the form of a multi-row ball-bearing rotary joint for carrying axial loads, radial loads and tilting moments. The large-size rolling bearing has an outer race, an inner race, a first ball row and a second ball row. The first ball row and the second ball row are respectively arranged in axially mutually spaced relationship in a four-point bearing configuration, associated with the first ball row are four raceway portions and associated with the second ball row are four raceway portions. The invention concerns in particular a large-size rolling bearing in which a surface of a respective raceway portion provided in the inner race is larger than the surface of the respectively adjacent raceway portion provided in the inner race and equal to the surface of the respectively diametrally oppositely disposed raceway portion provided in the outer race.
