The invention provides an oil lubricating roll-slide bearing with an elastic roller. The roll-slide bearing consists of an outer ring (1), elastic cylindrical rollers (2), slide blocks (3) and an inner ring (4), wherein the elastic cylindrical roller (2) and the slide block (3) are positioned in a chute between the outer ring (1) and the inner ring (4); the number of the elastic cylindrical rollers (2) equals to that of the slide blocks (3), and the elastic cylindrical rollers (2) and the slide blocks (3) are distributed at intervals; the diameter of the elastic cylindrical roller (2) is more than the thickness of the slide block (3) in the radial direction of the bearing, and the axial length of the elastic cylindrical roller (2) is less than the length of the slide block (3) in the axial direction of the bearing; the elastic cylindrical roller has a certain pre-compression amount in the diameter direction, trace clearances are reserved between the slide blocks (3) and the inner ring (1) and between the slide blocks (3) and the outer ring (4), and the elastic cylindrical rollers (2) are kept to be contacted with the slide blocks (3). The oil lubricating roll-slide bearing is used for reducing the applied stress on the inner and outer rings and the elastic cylindrical roller, has the characteristics of storing and releasing energy and maintaining rolling, and has small abrasion and long service life compared with those of a roll-slide bearing with a corresponding size.

The invention discloses a door for an office.
