Shaft bearing

The bearing for essentially parallel shafts (20, 30) consists of coaxial supporting sleeves (12, 13, 14, 54) that overlap at least partly in an axial direction, especially by the thickness of an intermediate wall (10) or at least 4 mm. The shafts can be level or eccentric, with one of the sleeves (54) formed inside the engaging portion of the opposite shaft or shutter; another is in the form of a seal (14).
