Linear Bearing

thingiverse

NOTE So, I see people "Liking" this and adding it to their collections, so I have been meaning to throw this not 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. Instructions Set screw holes are sized to be tapped with a #6-32 tap. See image for details on bearing adjustment.
