A system for securing a linear motion guide track, the system comprising: a linear motion guide track comprising a rigid, axial member having a track interface surface running the axial length of said linear motion guide track; a support extrusion comprising a axial member having at least one well disposed therein running the axial length of the support extrusion, and a plurality of conduits extending therethrough in a direction perpendicular to said axial length of said support extrusion; and the system being characterised in that said at least one well includes a slit disposed therein running the axial length of the support extrusion; wherein said support extrusion further comprises a wedge comprising a rigid, axial member, a first side and a second side opposite the first side, wherein the wedge further comprises a protrusion on the first side of said wedge and running the axial length of said wedge, and a plurality of deformable teeth on the second side of said wedge, said plurality of deformable teeth extending substantially perpendicularly from the axial length of said wedge; wherein said support extrusion is configured such that said slit of said at least one well accepts said protrusion of said wedge and said wedge partially fills said at least one well; wherein said support extrusion is configured such that said linear motion guide track is press-fitted into said partially-filed at least one well, thereby deforming said plurality of deformable teeth such that said linear motion guide track is securely held within said at least one well; and wherein at least a portion of said track interface surface protrudes from said at least one well. a linear motion guide track comprising a rigid, axial member having a track interface surface running the axial length of said linear motion guide track; a support extrusion comprising a axial member having at least one well disposed therein running the axial length of the support extrusion, and a plurality of conduits extending therethrough in a direction perpendicular to said axial length of said support extrusion; and the system being characterised in that said at least one well includes a slit disposed therein running the axial length of the support extrusion; wherein said support extrusion further comprises a axial member having at least one well disposed therein running the axial length of the support extrusion, and a plurality of conduits extending therethrough in a direction perpendicular to said axial length of said support extrusion; and the system being characterised in that said at least one well includes a slit disposed therein running the axial length of the support extrusion; wherein said support extrusion further comprises a wedge comprising a rigid, axial member, a first side and a second side opposite the first side, wherein the wedge further comprises a protrusion on the first side of said wedge and running the axial length of said wedge, and a plurality of deformable teeth on the second side of said wedge, said plurality of deformable teeth extending substantially perpendicularly from the a protrusion on the first side of said wedge and running the axial length of said wedge, and a plurality of deformable teeth on the second side of said wedge, said plurality of deformable teeth extending substantially perpendicularly from the axial length of said wedge; wherein said support extrusion is configured such that said slit of said at least one well accepts said protrusion of said wedge and said wedge partially fills said at least one well; wherein said support extrusion is configured such that said linear motion guide track is press-fitted into said partially-filed at least one well, thereby deforming said plurality of deformable teeth such that said linear motion guide track is securely held within said at least one well; and wherein at least a portion of said track interface surface protrudes from said at least one well.
