Abstract

A bearing arrangement for the pot of a centrifugal yarn spinning unit has a housing in whose cavity a radial bearing and an axial thrust bearing for the shaft of the pot are arranged. The radial bearing is fixedly mounted on a carrier which plugs an opening of the housing. The carrier is sealed to the housing by O-rings, and the shaft journaled in the bearings is received in a passage of the carrier provided with a packing in fixed spatial relationship with the radial bearing. Wear of the packing is minimized by the permanent guidance provided to the shaft by the radial bearing although the shaft may oscillate radially with the carrier during its high-speed rotation.
