Experimental 624z Linear Bearing by Acarius10 Aug 28, 2012

Description

After converting an original Mendel into a Prusa, I had scads of 624z Bearings left over. I designed this to use them on smooth rods.

I found tightening the nuts once the slider is on the bar makes it much smoother
Yeah I would roll the slider along the bar then take it off and see where it was rubbing and then file it down there to get the fit just right. Pretty clever design!
Very Cool!!! I've been trying to think of a way to use them. I was originally going to put them on my Prusa Z-Axis, but couldn't figure out a way to easily mount them. Putting washers in might help them roll a bit easier, but I found that as long as you didn't tighten the nuts and screws to tight, they rolled rather easily.

Instructions

1) Print as many as you need. 2) Take 3-624z bearings, insert into slots, put an M4 x 16 screw in each of the bearings. 3) Put nuts on the screws and tighten until the screw is no longer moving back and forth. Any tighter and the plastic will clamp down on the bearing, causing it not to move. 4) Slide over an 8mm smooth rod and move back and forth multiple times to loosen the item up a bit. It will be stiff when you first put it on, but after a while, it moves freely.

Have you thought about making the slots for the bearings a bit bigger so they can fit spacer washers?
I have a ton of these too, wanted to use them on this: thingiverse.com/thing:112718 but not sure if they'll work
Threadless Ball Screw. No More Backlash
Actually I'm going to use your design after all :)

Going to use it to make a camera slider I think.
