Now on sale, a new linear motion system from www.cncrouterparts.com! These unique components turn a standard 1/4" thick steel rail into a linear rail. No angled mounting or fussing with alignment of gas pipe -- just bolt a piece of steel to your extrusion, and use these for square, rigid, trouble-free motion. Pre-load the bearings using the integrated nylon set screws and the t-slots on the extrusion.
Cost wise, these are designed to be very competitive -- everything you need, aside from the rail itself, is included in the price. No eccentric bushings, and no custom machining. Mount these straight to 8020 as an integrated part of your frame. A complete linear motion solution for your machine can be had for as little as $120, plus the price of low cost steel rails. Want greater stiffness? Just add more carriages to spread the load -- they're completely modular.
Like all the parts we sell, these are designed to work with 8020 15 series aluminum extrusion, forming an integrated system with the other parts sold on the site.
