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 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.

A rolling-element bearing subassembly includes a first bearing ring having an axial face lying in a plane and a plurality of rolling elements on a running surface of the first bearing ring. The first bearing ring is connectable to a second bearing ring to form a rolling-element bearing. An annular retaining body having a first leg connected to a second leg by a bridge, the first leg being shorter than the second leg, is mounted on an axial face of the first bearing ring with the first leg contacting the axial face so that the bridge is located on a first side of the plane and the second leg extends through the plane to define an annular gap between a portion of the first bearing ring and the bridge and a portion of the second leg for retaining a lubricant.

A method of making an axle sleeve includes forming a main body comprising a cylinder and forming an expansion member whereby a diameter of the main body may be varied. The method includes cutting an inner helical cutout comprising a first slit defined through the main body and extending helically from an inner edge of the main body, cutting an outer helical cutout comprising a second slit defined through the main body and extending helically from an outer edge of the main body, forming an inner edge remaining portion comprising an annular section of the main body unbroken by the inner helical cutout, and forming an outer edge remaining portion comprising an annular section of the main body unbroken by the outer helical cutout.

This mobile-object-holding tool is mounted in place of a track body on a mobile object which moves along the track body, wherein the mobile object includes at least a pair of rolling element load rolling grooves through which a plurality of rolling elements roll and the mobile-object-holding tool includes a pair of holding parts which face the pair of rolling element load rolling grooves and hold the plurality of rolling elements, a biasing linking part which links the pair of holding parts together and biases the pair of holding parts away from each other, and a deformation regulating part which regulates a mounted contraction amount by which the biasing linking part is capable of contracting after being mounted on the mobile object to a predetermined value or less.

A bearing assembly includes first and second rolling-element bearings each having first and second bearing rings, a raceway and a flange element at both ends of the raceways. Two of the flange elements are formed on a common flange body, and the flange body is axially pressed onto cylindrical mounting surfaces of the first bearing rings of the first and second rolling-element bearings and held in place by a press fit.
