A fluid-actuated rotary drive device (1) and an output assembly (36) for the rotary drive device (1) are provided. The output assembly (36) comprises an output body (38) which is rotatably installed or can be rotatably installed on a drive housing (2) of the rotary drive device (1) using a rolling bearing (37). The output body comprises at least one fixing interface (42) to allow a driving power transfer. The rolling bearing (37) has a self-binding structure and comprises an inner ring (63), an outer ring (64), and a rolling element (65) disposed therebetween. The rolling bearing (37) and the inner ring (63) thereof are installed on the output body (38) from below, and fixed on the output body (38) by first tensioning means (25). In this way, the output assembly (36) can be handled as one unit. In an assembled state, the output assembly (36) is pushed into the drive housing (2) from above and fixed on the drive housing (2) by using second tensioning means (26) cooperating with the outer ring (64) of the rolling bearing (37). |
