Robo3D R1 Alternative Y Axis Pillow Block

This is a replacement / upgrade to the Robo3D R1 and the LM8UU linear bearings used to guide the Y Axis of the moveable bed. This model uses self-aligning self-lubricating sintered bronze bushings instead of ball bearings. Advantages are operation with less mess as little or no lubrication is needed along the rails. Quieter operation from the solid bronze bearings. No possibility of gouging the rails in the event of a bad or dry ball bearing.

This pillow block uses 7Z41MPSB08M bearings availa
