Rodless Actuators (screw drive) Rodless Actuators (belt drive) Precision Tables Notes: 1. Electric cylinders are designed primarily for thrust application where loads are supported externally. 2. Thrust ratings are based on mechanical limits rather than motor limits unless indicated otherwise. 3. Max speed and max thrust ratings are not necessarily available simultaneously 4. Repeatability is dependent on feedback resolution, load, friction, and drive gain settings. 5. Repeatability is unidirectional unless otherwise specified Because Motion Matters" LINEAR ACTUATION & POSITIONING SYSTEMS

Electric Cylinders Kollmorgen Electric Cylinders offer a cost effective solution for linear positioning of supported or pivoting loads. They are descendents of hydraulic or pneumatic cylinders with many of the same design features but offer the benefit of providing a simpler and cleaner transmission. When high thrust is required these rod type cylinders have the advantage over other linear components because the thrust is transmitted in-line. They also have the advantage of being isolated from the work area so can retract during other operations. Flexibility in mounting allows either rigid...

EC Servo Linear Actuators Electric Cylinders Are Preferred When: • Positioning an externally guided and supported load. • Moving a load that pivots. • There is a high concentration of airborne contaminants (rodless actuators are inherently less well protected). • Replacing a hydraulic or pneumatic cylinder with an electro-mechanical solution. 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...

Electric Cylinders Features E L E C T R I C Electric cylinders are direct descendents of hydraulic and pneumatic cylinders. Possessing many of the same unique design characteristics that made hydraulic and pneumatic cylinders popular, electric cylinders benefit from a cleaner and simpler power transmission. Decades of electric cylinder research and development has provided machine designers with a flexible, simple and unique approach to solving rigid or pivoting linear motion applications. Electrically Powered, Maintenance Free Today nearly all machines incorporate panel switches, sensors,...

ELECTRIC CYLINDER DRIVE COMPARISON Electric Cylinder Drive Comparison The following chart will help pinpoint which linear drive mechanism is right for your application. Kollmorgen offers many positioner options, such as brakes, encoders, lubrication ports, preloaded nuts, and precision ground screws, that may help you meet your specification. If these standard options do not meet your requirements, please contact Kollmorgen for information regarding custom solutions.

Lead Screw: Sliding nut design provides quiet operation. Ball screw: Transmits audible noise as balls recirculate through nut during motion. Lead Screw: Good for vertical applications. Ball screw: May require brake or holding device when no holding torque is applied to the screw. Lead Screw: Considered worn-out when backlash exceeds 0.020". Typically 0.006" when shipped from factory. Ball screw: Typically constant at 0.006" (screw/nut only). Lead Screw: Low duty cycle due to high friction from sliding surface design. Ball screw: High screw efficiency and low friction allow high duty cycle....
