Apparently I am not searching the right place for this since I am striking out. I assume it actually exists but don’t really know.

Any guidance would be great.

I need a 1.5” – 3” wide roller bearing that can be halfway recessed into a board so the roller is mostly hidden bur protrudes enough to allow something to roll on it. I am thinking that the roller would be something like .5” in diameter and possibly mounted in a metal “cup”

I am trying to make a drawer for my pickup bed and the drawer itself will be almost 70” long and I want it to ride on a series of low profile bearings. I think i need cylindrical rollers not the ball bearing rollers due the weight of the drawer.

here is what i am trying to replicate.

A pre assembled slide would be nice however they add $500 or more to the project… I am hoping to find some roller of sorts.

Thanks in advance
Adam

Given those dimensions I doubt the roller will roll once there is a bit of weight upon it.

I’d suggest UHMW. It can be drilled, countersunk and screwed on a surface. 1/4” thick would work. You wouldn’t need to cover the whole surface, just maybe 4 inches on each side.

Here’s a source I got via Google:

http://www.plasticsintl.com/uhmw-sheet.html?filter[1]=&filter[2]=0.25&filter[3]=&filter[4]=

This one is pretty reasonable—12×60 x .25 for twenty three bucks!

Kindly,

Lee

You’ll need rollers on top too.

I could see something with 3 lengths of unistrust on
each side, 2 screwed to the carcase side, 1 to the
drawer side. You could fit rollers top and bottom
in the unistrut side. You’d have to have a way
to manage how proud each roller is of of the
side of the strut in which it is mounted. Maybe
wood could be substituted somehow but it
will wear out and not stay as straight.
