The SBR/TBR Series supported rail linear systems combine hardened steel shafts with continuous aluminum rail support, eliminating shaft deflection over long spans. Paired with matched linear ball bushings, these pre-engineered systems provide ready-to-install linear guidance for material handling, automated conveyors, and gantry robot applications.
