Beschreibung
Zusammenfassung:	A two-stage cross roller bearing ( 1 ) includes a first cross roller bearing ( 10 ) and a second cross roller bearing ( 20 ) that are disposed concentrically along a plane that is perpendicular to the bearing axis 1 a. The inner ring of the first cross roller bearing ( 10 ) and the outer ring of the second cross roller bearing ( 20 ) are formed of a single ring-shaped member ( 14 ), with an inner ring-side raceway groove ( 13 ) of the first cross roller bearing being formed on the circular outer circumferential surface of the ring-shaped member and an outer ring-side raceway groove ( 21 ) of the second cross roller bearing being formed on the circular inner circumferential surface of the ring-shaped member. A small, compact, and flat multistage cross roller bearing is realized.
