Are these parts from my valkyrie

I am in the process of removing the rusted out swing arm. So far I removed the rear fender, brake caliper, rear wheel, and rear drive unit. I found these bearings and cup washer on the floor, under the bike. Did they fall out from somewhere? Washer is 26mm with a 9mm hole and bearings are 4mm.

Looks more like a seat creeper pivot wheel brg. Can't  think of any brg assebly like that on a Valk.

Good call. I did remove the broken casters from a metal computer desk not to long ago.
I guess I should clean the work area before starting new projects.

Looks like a Axial Ball Thrust Bearing and you are missing some balls and one side. I just replaced one on my motorcycle jack.

If you don't mind me asking, how would the cup washer and bearing fall off the caster wheel though?

[edit] the mystery bearing is so cheap it didn't have a bearing cage. How much could the manufacturer possibly have saved?

[Skinhead]

The ball cage is used to maintain spacing between the balls.  In the case of bearings with a full, one-piece inner and outer race, the balls have space between them so they can be grouped to one side, allowing room to install the inner race.  The balls are then spaced evenly around the races and the cage added to maintain the spacing.  In a bearing that is split perpendicular to the axis, there is no need to group all the balls together to install the split races.  Enough balls are added to one half of the bearing to take up all the room in the race, then the 2 races are assembled together, since all the space is occupied by balls, there is no need for the spacer.  The neck bearings in a bicycle are a good example of this.  If a split bearing's races are loose enough to allow a ball(s) to fall out, they will all eventually fall out.

I did not know that.

I guess wages must be cheap at the factory to assemble bearing by bearing instead of a single motion with a caged bearing.

Almost every pivot wheel on every piece of  furniture I've seen has been this way. No cages.
Labor is cheap where most of this crap comes from.
