Does anyone out there know of a source of proper F8-16M ball thrust bearings?

Does anyone out there know of a source of proper (not too expensive) F8-16M (8 – 16 x 5mm) ball thrust bearings?

By ‘proper’, I mean that both end ‘washers’ have ball grooves in, and the washers are not identical:

one washer’s central hole fits the shaft snugly, while its outer diameter is slack in the bore, while

the other washer is slack around the shaft, while its outer diameter fits the bore snugly

This kind of 8mm hole, 16mm diameter, 5mm thick bearing (see photo) can be found cheaply from many sources and the one I have bought are made remarkably well – they can carry large axial load smoothly – but every one I have has a pair of identical washers (with 16.0mm outer diameters and ~8.3mm holes) that both want to grip the bore and both slop-around on the shaft – and therefor confer no radial location.

Oddly, when I buy F8-19M ((8 – 19 x 7mm) or F8-22M thrust bearings, made to a similar price and arriving with similar quality, I get proper different washers which go on to locate the shaft radially as well as resisting thrust – so far, at least.

BTW, some similar-sized thrust bearings have flat washers – with no grooves – and therefor have no radial location capability either, and roller-type thrust bearings at this price also have flat washers and no radial location.

The F8-22M has the same 8 – 19 x 7mm dimensions as the classic ‘608’ radial skate bearing, so beloved of home constructors. The ones I bought had the same sized ball ring as the F8-19M types, just with wider washers, making me wonder if F8-22M is a made-up thrust bearing to match the 608.

Having radial and thrust bearings in the same size allows a fully-located bearing for not-too-critical applications to be made from three cheap bearings rather than a pair of expensive angular-contact bearings or a pair of expensive taper roller bearings.
