In the first picture the white piece is for a sliding glass door for the shower, the glass is curved and goes on the top. Its broke on the inside so I cant really show what's broken. The second picture is from a Lazy Susan cabinet, the screw for the hinge is not tightening for some reason.

For the shower door roller, see our 10-058. As for the hinge, the closest we have is our 39-346 though I do not know if it can work. You may need new installation holes. I'm sorry we cannot offer something closer.
