I used to know that a single full-electric linear actuator (with reduction gears) is not suited for thrusts higher than a ten tons, and strokes in the one-meter-maximum range. I know farmers offer catalog products promising even much better features (force and stroke). However, is anybody witness of practical applications of these geared full-electric linear actuators, and what is the experience reported mainly on the side of machine affordability and durability (I'm not interested in discussing the fault-tolerance against ball-screw seizure and winding short-circuit, which is obviously completely lacking in these kind of drives)? And, finally, what about competitive full-electric cylinders or flat-type linear permanent-magnet actuators?
