ABSTRACT:
A gas static bearing unit for carrying rollers which is suitable as a heat-resistant bearing inside a horizontal furnace for glass sheets. The bearing unit consists of a bearing 1 which automatically adapts to the orientation of the section of roller 27 mounted in the bearing 1 and which rests on two pins 8, 9 each having a spherical head 16, 17 as a support surface. The first spherical head 17 is mounted stationarily and oscillatingly, and the second spherical head 16 is mounted on a planar base 23 to allow pivoting and sliding around the stationary pin 9. A system of bores 30, 31, 32, 33 makes it possible to supply the rotating clearance with compressed air.
