A barrel-shaped bearing which comprises an external ring and an internal
ring, at least one row of barrel-shaped rolling bodies arranged
therebetween, the cage in the form of a disk which turns together with
the rolling bodies, engages inside a peripheral groove around each
rolling body and is provided with recesses corresponding to the number of
the rolling bodies of the one row arranged on the external periphery of
the cage. The total rolling surface of the internal ring is embodied such
that the cross section thereof is concave along the entire axial length
of the rolling body. The smallest distance between both sides of the
cavity of the disk-shaped cage in the area of the external periphery
thereof is less than the diameter of a rolling body in the area of the
peripheral groove thereof.
