The invention relates to a fastening device, in particular a mount, which is designed and configured to receive bearings of a textile machine, in particular a rotor spinning machine, comprising at least one inner ring region and at least one outer ring region. In order to improve the safety of the operation of a textile machine, to extend the service life of a textile machine and thus save resources, and to improve the operation of a textile machine, the inner ring region and the outer ring region are formed as a single piece.

A shaft assembly has a shaft and a journal bearing that is fixedly coupled to the shaft so that rotation of the shaft causes corresponding rotation of the journal bearing. A bearing race has an inner surface that defines a cylindrical bore and a lubrication groove that extends radially outward from the cylindrical bore. The journal bearing is rotatably disposed within the cylindrical bore of the bearing race.

The present disclosure relates to a multi-track ball bearing system for the top roller in the textile industry. The multi-track bearing system has been developed with a core concept of a detachable and serviceable design to achieve the highest quality impact on the extracted sliver and yarn. Textile spinning mills will benefit from low maintenance by avoiding repeated roller replacements and achieving consistent quality in the sliver and yarn output to effectively serve their end customers. The design also allows for repair and recycling by reusing good functional parts and replacing worn-out parts. This can be done by the top roller manufacturer as needed and ultimately reduces the environmental impact due to the inherent benefits of recycling.

To provide a bearing for reducing the material fatigue of a machine.SOLUTION: A bearing (25) for a shed forming machine or a system for transmitting a motion to a frame of a loom comprises an inner ring (72), an outer ring (74) and rolling elements (76). The inner ring has two lateral surfaces vertical to a long axis and centered on a main axis line (A72), and defines a circular external peripheral ring (80) centered on the long axis line. The outer ring (74) defines the circular inner ring (72) centered on the main axis line. The inner ring (72) comprises at least one slot (90), is open onto the two lateral surfaces, extends opposite a part of the external peripheral ring (80), and forms a material bridge (94) between the slot and the external peripheral ring. The material bridge (94) extends above an angular sector (99) of the inner ring, the angular sector being centered on the main axis line (A72) of the bearing and having a vertex angle (α1) which is larger than a vertex angle (β2) of an angular sector occupied by the two rolling elements (76), or equal thereto.SELECTED DRAWING: Figure 4

The present invention relates to a roller device for guiding a material web, in particular a fibrous web, comprising a hollow cylindrical roller shell rotatable about an axis of rotation (R), a first bearing section and a second bearing section arranged inside the roller shell and connected to it in a rotationally and axially fixed manner, wherein the first bearing section has a first axial extension which is mounted in a first receiving section of a first bearing plate arranged on one of the end faces of the roller shell in such a way that a fixed bearing is formed, and wherein the second bearing section has a second axial extension which is mounted in a second receiving section of a second bearing plate arranged on the other end face of the roller shell in such a way that a floating bearing is formed.
