The REV 15mm Extrusion System uses plastic acetal (Delrin/POM) molded bearings and linear slides to create smooth, low friction rotational and linear motion interfaces. Bearings have a maximum 9mm outer diameter (OD) which fit inside the 9mm inner diameter (ID) hole in the all the motion brackets. The diagrams below depict several common configurations for bearings, linear slides, & pillow blocks. For more examples and building guides, please check out our Tech Resources page.
