Hello,
I've seen these casters that simply a rubber ball in a steel housing with a plate for attaching. There are probably some ball bearings fit in that housing somehow as well. I've googled and otherwise searched the web to no avail. I've called a few contractor hardware places in the area and while they know what I'm talking about no one has a clue where to get them.
I'm not talking about the stem type ball caster you see used on chairs. This is a plate caster, plate 4-6" square with the ball centered w/respect to the plate and held in place w/enough of a steel sphere to keep it there. The idea is a very very smooth swivel.
Anyone have a source for these casters?
Anyone have any experience with them, i.e. do they suck? I'm thinking they'd be a lot easier to find if they were popular.
thanks for the help ml
