The operation of rodless actuators is similar to the electric cylinders described earlier. However, instead of an extending rod, a
            rodless unit features a moving carriage supported by linear bearings within an extruded aluminum chassis. This gives the rodless
            actuator the ability to guide and support a load, as well as position it.

            Kollmorgen rodless actuators are designed for outstanding overall performance, value, flexibility and reliability in industrial
            applications.                                                                                               LINEAR A
