Abstract

A large roller bearing has an inner ring and an outer ring, raceways for rolling elements received between these raceways, a first and a second end face. First fastening means extend from the first to the second end face, wherein each of the first fastening means is aligned with a bore of a first connecting element. An adapter ring extends from the outer or inner ring axially toward the first or a second connecting element. The adapter ring has a first and a second end face, and second fastening means extend from its first to its second end face, and each second fastening means is aligned with a bore of a second connecting element. Third bores are spaced apart from one another, wherein each of the third bores is aligned at the first end face of the adapter ring with a bore of the outer ring or the inner ring.

the inner ring and the outer ring are separated from each other by a bearing gap and have respective raceways for rolling elements received between these raceways;
the inner ring and the outer ring each have a first and a second end face;
the inner ring or the outer ring has a plurality of first fastening means which are arranged at a distance from one another and form a first fastening collar;
wherein
each of the first fastening means is provided and designed to align with a respective fastening element of a first or second connecting element;
an adapter ring is provided and designed to extend the outer ring or the inner ring in the axial direction toward the first or second connecting element;
wherein the adapter ring
has a first and a second end face,
has a plurality of second fastening means which are arranged at intervals along the circumference of the adapter ring and form a second fastening collar, each of the second fastening means being provided and designed to be aligned with a respective fastening element of the second or first connecting element;
has a plurality of third fastening means arranged at intervals along the circumference of the adapter ring and forming a third fastening collar, each of the third fastening means being provided on the first end face of the adapter ring with a respective fastening means of the outer ring or the inner ring;
and
