The utility model relates to a half-opening type self-aligning sliding bearing with a damping device. The sliding bearing comprises a bearing seat, wherein a main bearing bush is mounted on the bearing seat; a damper is arranged above the bearing seat; a sliding plate of which the height can be adjusted is arranged on a box body of the damper and is positioned above a compressing bearing bush; pre-compressing springs are arranged between the sliding plate and the compressing bearing bush; the main bearing bush is a combined bearing bush composed of an outer bearing bush, a middle bearing liner and an inner bearing bush; the inner surface and the outer surface of the inner bearing bush are respectively a cylindrical surface; the inner surface of the middle bearing liner is a cylindrical surface matched with the outer surface of the inner bearing bush; the outer surface of the middle bearing liner is a spherical surface matched with the inner surface of the outer bearing bush; the inner surface of the outer bearing bush is a spherical surface; the outer surface of the outer bearing bush is a cylindrical surface; and the lower surface of the compressing bearing bush is a cylindrical surface. The sliding bearing provided by the utility model is low in friction coefficient, high in load bearing, resistant to a high temperature and free of load impact. Thus, the sliding bearing provided by the utility model is especially suitable for serving as a large self-lubricating bearing in the fields of petrochemical engineering, wind power generation and the like.
