Linear Motion Guidance

Linear motion systems are supported and guided by linear bearings. The function of all linear bearings is to bear loads while ensuring stable and accurate linear motion. The three basic categories of bearing technology are recirculating element, plain, and cam rollers. The four basic bearing “shapes” are round shaft (round rail), profile rail (square rail), cam rollers, and drawer slides (telescopic slides).

When selecting a linear motion system, one can choose to design and assemble the components or buy a pre-assembled solution. Pre-assembled systems can be called actuators, stages, slides, tables, or positioners. Bearings and linear guide selection is based on: loads, speeds, duty-cycle, required life, rigidity, accuracy, machine configuration, and installation limitations.
