Abstract
A bearing disk construction is disclosed for an open end spinning rotor at a spinning unit of the type having a rotor mounted on a rotor shaft, a twin disk bearing arrangement for rotatably supporting the rotor shaft and a tangential belt drivingly engaging the rotor shaft of the radial side thereof opposite the twin disk arrangement. The bearing disks are formed with a metallic base body and a plastic fitting around the circumference thereof which directly supportingly engages the rotor shaft. To minimize heating of the system during high speed operation, the plastic fittings are provided with a circumferential ring groove which is geometrically configured to optimize bearing support and heat dissipation. The plastic fitting is anchored in a groove at the circumference of the base body by moulding the plastic at the base body.
