A first cage part designed as a snap cage having axial webs projecting in the direction of the axis of rotation from a closed base ring and form ball pockets therebetween them, the first cage part encloses the balls along their outer circumference by more than 180° , holds the balls positively while forming an undercut and limits displacement of the balls within the circumferential surface in the direction of the at least one other second cage part.

A bearing assembly of a rotor of a wind turbine, for mounting a shaft of the rotor in a fixed housing, wherein the shaft of the rotor is coupled to rotor blades of the rotor via a hub, includes: a plurality of first housing-side axial slide bearing segments engaging on the housing; a plurality of second housing-side axial slide bearing segments; a plurality of first housing-side radial slide bearing segments; and a plurality of second housing-side radial slide bearing segments. An axial distance between the first and second axial sliding surfaces of the rotor defines a bearing length l. The radial sliding surfaces of the rotor on which the first and second radial slide bearing segments are supported, define a bearing diameter d of the bearing assembly, and V≤1 applies to a ratio V=l/d between the bearing length l and the bearing diameter d.

A blood flow assist system can include an impeller assembly including an impeller shaft and an impeller on the impeller shaft, a primary flow pathway disposed along an exterior surface of the impeller. The system can include a rotor assembly at a proximal portion of the impeller shaft. A secondary flow pathway can be disposed along a lumen of the impeller shaft. During operation of the blood flow assist system, blood can be pumped proximally along the primary flow pathway and the secondary flow pathway. The system can include a sleeve bearing distal the impeller. The system can include a drive unit having a distal end disposed distal a proximal end of the second impeller. The drive unit comprising a drive magnet and a drive bearing between the drive magnet and the impeller assembly.

The resin injection gate is disposed at the pillar part. When the bearing cage is divided into first and second regions by an imaginary line connecting the resin injection gate and a weld to be formed at a position radially facing the resin injection gate, a resin reservoir that can store therein the melted resin is formed at the pillar part in only one of the regions. A circumferential distance between the resin reservoir and the weld is smaller than a circumferential distance between the resin reservoir and the resin injection gate. A cross-sectional area of a communicating part of the resin reservoir, which is configured to communicate with the pillar part, is equal to or less than a quarter of a cross-sectional area of the resin injection gate.

A deep groove ball bearing includes an outer ring, an inner ring, a cage, and steel balls. The cage is provided between the outer ring and the inner ring. Pockets are formed in the cage, and the steel balls are placed in the pockets. The cage is split into an upper cage body and a lower cage body. Pocket grooves are formed alternately in each of the upper cage body and the lower cage body. A connecting portion is provided between adjacent pocket grooves in the upper cage body. A positioning portion is provided between adjacent pocket grooves in the lower cage body.
