Bearing unit for high rotational speed, particularly for spinning rotor of open-ended spinning machine, has bearing housing that has radial relubrication opening, and spindle that has conical area

摘要

The bearing unit (1) has a bearing housing (2), in which roller bearings (3,4) are stored. A spindle, protruding from the bearing housing, is arranged with both ends (7,8). The bearing housing has a radial relubrication opening (19). The spindle has a conical area (21). A diameter of the spindle is increased itself according to the relubrication opening in a direction of the roller bearings. A largest diameter of the conical area of a receiving groove (23) is arranged in the bearing housing.
