Nowadays, sliding bearings are usually used which apply the so-called plug-shoe principle to level-out dynamic movements of the surrounding. In this application, there is proposed a sliding bearing for airplanes comprising a frame, a carrier plate and a fast-locking element. The fast-locking element may allow for a mounting of interior installations at the sliding bearing perpendicular to the ceiling surface. Further, by means of the sliding bearing according to the invention, an unintended gliding-out of the carrier plate out of the frame may be prevented. In this way, a light and cost-effective sliding bearing may be provided, by means of which the mounting effort of interior installations is facilitated.
