These bearings are often used to achieve linear movement in 3D printer builds. They will move smoothly along an 8mm diameter linear rail.
UU series linear bearings feature rubber seals on each end of the bearing, in order to protect the bearing against the ingress of dust, moisture, and other debris.
Many 3D Printers / RepRaps will use these bearings in x/y/z-axis movement.
