Glacern cnc 20MM 25" linear motion guides (thk thomson)
Glacern SBR20 20mm Supported Linear Motion Set
GMT SBR supported linear rails and ball bearing blocks are perfect for building professional quality CNC routers, CNC plasma cutters, positioning systems, gantry robots, and other automated applications.
Compared to unsupported round rails, SBR rails provide drastically enhanced rigidity and resistance to deflection. They are also easier to install and are less prone to binding than rectangular-profile linear motion guides when they are mounted to surfaces that have not been precision machined, such as aluminum extrusions, steel tubes, and unsurfaced steel/aluminum plates.
Rails and bearings conform to standard "SBR" metric dimensions and specifications, allowing them to be used in both new applications as well as existing installations.
This action is for one set, which includes TWO (2) rails and FOUR (4) blocks. The length of the rails are 25" each.
