V groove casters

[AustinT]

Would V groove casters work well for a linear setup? They are cheap and easy to get.

Here is a link to some casters that might work

I dont know how tight the bearings are in the casters but the casters could be used horizontally and vertically at the same time. With this arrangment the gantry would not be able to move side to side on the rails.

What do you think?

This one can be bought without a bearing. Then a precision bearing could be used.

I don't want to burst your bubble but do you realize that these casters are made out of iron. Iron is heavy and the combined weight will add up quickly leaving you with a large inertial moment.

Yes that is a problem. I found a caster with a 3 inch diameter. If I could find one with a 2 inch it would be even better. Thanks for the feedback.
