NOTE

So, I see people "Liking" this and adding it to their collections, so I have been meaning to throw this in here for a long time, but finally got around to it today. I modeled this 7 years ago when I was an engineering student, and after much experience with linear motion mechanisms, I just have to say, this really is not a very good design at all and I would advise against using it. I am tempted to delete it, but have decided to leave it up.

As I look at it now, it is really a poor design, starting with the fact that you are using a "flat" surface (outside edge of 608 bearing) to traverse a curved cylindrical surface (linear rod). Anyway, I just wanted to throw that thought out there for whatever it is worth. Thanks.

Linear Bearing designed for 608 (skate) bearings and M8 or 5/16" bolts. (File is in Inventor 2011 format, as well as STL). Designed for a 1/2" rod. Two of the six bearing holes are slightly oval to allow for adjustment via the set screws.

Based on Dave Kush's Design (http://www.buildyouridea.com/cnc/hblb/hblb.html)

Update #1 (06-OCT-2010):

• Fixed scaling issue in STL file.

Update #2 (06-OCT-2010):

• Added mounting holes.
• Added additional STL file without mounting holes.

Update #3 (06-OCT-2010):

• Modified one set of bearing holes to be slighting oval.
• Added set screws to allow for bearing adjustment.
