12mm Diameter Linear Bearing Pillow Block - SBR12UU
Product Images and Video
Make your robot or CNC move on our Aluminum Slide Rail with this sliding linear ball-bearing platform AKA pillow block. The slider is 39mm x 36mm and has four holes tapped for M5 machine screws so you can attach pretty much anything you want. This slider has a plastic interior with small metal ball bearings to make it slide easily and smoothly.
The platform won't come off the railing but it does rotate a bit around so for best stability, use two support rails. Often times, CNC projects will have two of these on opposite sides of the machine body to support a larger platform. You can also have some other support mechanism of your own devising.
Comes as a single bearing platform. You'll want to pick up at least one 12mm railing as well. We have a bunch of bearings, supports and platforms that you may want to use with an 8mm based rail system so check out our CNC category
