A system having a rolling bearing providing at least an outer ring, at least an inner ring and at least a seal, which seals an inner space of the rolling bearing on a first axial end of the rolling bearing against ingress of liquids and dust. The system further provides a transportation safety device, which is attached to the rolling bearing and restricts swiveling of the inner ring relative to the outer ring in comparison to a state of the rolling bearing in which the transportation safety device is detached from the rolling bearing.

A connector holding mechanism includes a biasing member provided in a through hole formed in a bottom plate of a storage body, a cover having a connector insertion hole and an inclined surface which is fixed to the through hole, a connector, in which a terminal is loosely inserted into the connector insertion hole, and a flange portion protruding from an outer periphery of the housing biased by the biasing member. When the connector is waiting to be fitted to a stored object, the connector is held in a posture where the terminal is inclined due to abutment between the inclined surface and the flange with respect to a virtual line perpendicular to the bottom surface, and when the connector is fitted to the stored object, the connector is held in a posture where the terminal is vertical along the virtual line.

A rolling bearing having an inner raceway and an outer raceway and a plurality of rolling elements arranged therebetween. The rolling bearing is media-lubricated or oil-free lubricated. The lubricant forms an elasto-hydrodynamic lubricant film between the rolling elements and the raceways. At first use of the rolling bearing, at least one surface of the rolling bearing is coated with a protective fluid, preferably an oil-based preservative fluid. Also, a refrigerant compressor having such a rolling bearing.

A method for assembling a rotor bearing arrangement of a wind turbine, includes the method steps: providing a rotor shaft; providing a bearing block; providing individual slide bearing pads; inserting the slide bearing pads in the bearing block; and joining the rotor shaft and the bearing block fitted with the slide bearing pads.

A transport-securing unit for retaining a plurality of rollers in a rolling-element bearing cage during transportation may include an annular region and a plurality of axially extending, circumferentially spaced projections extending from the annular region. Also, an assembly of the transport-securing unit, a rolling-element cage and a plurality of rollers in pockets of the rolling-element bearing cage, where the transport-securing unit is formed separately from the rolling-element bearing cage, and where the projections extend inside the cage and limit radially inward movement of the rollers relative to the cage.

A packaging system having an outboard guard and an outboard retainer cap. The outboard guard includes an outboard guard opening having a hole through the planform of the outboard guard, an engagement portion having an annular surface radially surrounding the outboard guard opening, an outboard bearing protector portion having an annular surface radially surrounding the engagement portion of the outboard guard, and an outer rim having an annular surface radially surrounding the outboard bearing protector portion. The outboard retainer cap is configured to be removably affixed to the outboard guard and includes an outboard alignment protrusion having a circular surface, an engagement portion having an annular surface radially surrounding the outboard alignment protrusion, and a retaining flange having an annular surface radially surrounding the engagement portion of the outboard retainer cap.
