The FrightProps High Speed Linear Actuators are built from a tubular aluminum alloy, light weight body, integrated with high speed planetary gear motor. The speed is 9" per second (230mm/sec) at no load with a force of 22lbs. The actuators are suitable for any type of indoor/outdoor application where high speed stroke is required and/or very low noise, measuring only 5dB above ambient. These actuators look great, are fast, versatile and quiet.
