The invention belongs to the technical field of steering engines and particularly relates to a finite swinging angle combination bearing. The finite swinging angle combination bearing mainly comprisesan output shaft, a front end face holder, front end thrust rollers, a support, a front end roller pin roller, a front end roller block ring, a rocker arm, a roller inner ring, a back end roller pin roller, a back end roller block ring, a back end face holder, back end thrust rollers, a locking end cap, a fastening screw and a countersunk head screw. The problems that an inner ring and an outer ring of an existing bearing of a discrete structural form need to occupy a part of space, and an output shaft and a shell assembly of the output shaft need to be designed to limit axial movement of theroller pin roller bearing, so that the size and the weight are increased are solved. The finite swinging angle combination bearing adopts functional reuse, the output shaft partially achieves the function of a bearing inner ring, the support partially achieves the function of a bearing outer ring, thus the size and the weight are significantly decreased, and the function of the combination bearingis enhanced.
