Bearings
Linear bearing is rectilinear motion system. Due to the fact that the ball and axle are point-contact type as well as smaller work load and the ball rotation under the smallest bearing drag linear bearings can support smooth long-term and high-accuracy running.
They are extensively used in electronic aid tension tester digitized three-dimensional coordinate measurement system and slide unit of multi-spindle machine punch grinders automatic gas cutting machine printer card cull eliminator food packaging machinery etc.
