I am looki g for 4, 3/4 od x 1/4 id deep grooved pulleys x 1/4 thick

Dear friend Sorry , we don't have

How much weight can these handle?

They have a small inside diameter so they probably should be used for non-weight bearing loads, ie: rotational loads, like router bits and 3d printed joints; not pulleys.

B**N

These bearings are rough. They roll smooth enough for my purposes but they feel like they will degrade quickly under pressure. I'm using them on a MK8 extruder for a 3d printer. Glad I have a bunch of them...
