Re: [CAD_CAM_EDM_DRO] I'm looking for a source of eccentric bushings.

I have always just drilled an off-center hole in the end of a big bolt, then cut the bolt the right length to fit the hole. You then have a hex to wrench on to adjust the amount of offset. If you have access to a lathe with a 4-jaw chuck, you can offset the bolt just the desired amount by offsetting it with a dial indicator. Then you can face off the end so the hex portion is about half or so of original. You can do a bunch in a short amount of time. You could still do it in a drill press, but a lathe is easier.

The hex gives you a good place to put a wrench on to dial in the right amount of squeeze.

Hope this helps -

Eccentric bushings are like bushings, except the inner hole is off
centered (eccentric)


I know I could make them, however I'm trying to find a supplier that
already has them for sale.


I looked at mcmaster.com, and tried to google it...


I've found lots of eccentric washers... and roller blade eccentric
spacers (which may work, but are flanged).


I'm looking for a spacer/bushing of the following features:
- 1/2" OD
- 1/4" ID.
- 1/4" to 1/2" thick. (I hope I can choose or something).


This would be used to adjust bearings/cam followers. I know that there
are eccentric cam-followers. However they're expensive, when I need
quite a few of them. So, eccentric spacer, bolt, and standard radial
bearing = cheap. :)

Cheap is good, when it does the same job.


If anyone knows where I can find some for sale, it would be greatly
appreciated.


Thanks.
