Camber plates

[Lajoosh]

bump the question.
they are cheap and also look cheap machined lasercut steel plates with lathed bearing housing welded in. this is the cheapest way you could produce a camber plate. even though these parts will do the job. the real question is: what spherical bearing do they use. the most of the spherical bearings are designed to deal with radial loads but in this case they get high dynamic axial loads. in the exact direction the outer ring was squashed around the ball. this application needs special axial loadable bearing for it to withstand longer use. since these are rare, they are expensive and this expense is not reflected in the retail price of these camber tops. though i cuold be wrong. but i think these are cheap 2 piece plain bearings, non self lubricating steel on steel, a strong type that wont break but wont last long until they become loose.
im also interested in these, i want some reasonable priced, non fancy badged camber tops for street use.
its a shame theres no information provided on their website:
