ball bearing
Bearing
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.
