Every day we are surrounded by things that move in a linear fashion. At THK, our roots lie in our initial development of a Linear Motion (LM) Guide that can guide a device accurately along a straight line. This manufacturing know-how has let us keep expanding the range of linear guidance products we produce to the present day.

Our LM guides are used for guidance of large automatic glass doors in many new intelligent office buildings. Conventional plastic resin rollers could not be used because of the increased weight of such doors and the windblast. Our LM guides solved these problems. They also make the door mechanism more compact and allow more freedom in door design.
