Kollmorgen offers electric cylinder drive mechanisms designed around either lead screws or ballscrews.  Ballscrews,
            being the more efficient of the two, utilize ballnuts riding on recirculating ball bearings resulting in higher speeds, loads and cycle rates.
            However, the more efficient design of ballscrew technology lends it to being backdriven when power is removed if precautions are not
            taken (e.g., electric brakes or counter loading).
            Lead screws are capable of holding the load in position when power is removed, but are less efficient in operation.
            Kollmorgen’s guide system prevents rotation of the ball / lead nut, thus eliminating any torque loading to machine linkage.


            Electric Cylinders Are Preferred When:                                                                      LINEAR A

            • There is a high concentration of airborne contaminants (rodless actuators
             are inherently less well protected).                                                                       A
