RE: [PSUBS-MAILIST] linear actuator- thruster range



Howdy Frank, thanks for the info.  1 inch a second is pretty slow.  OK for a manip possibly if it has a high load.  Which model was the Firgelli you bought?  Looks like they are 1”/sec as well. I would like to find a good one like the teledynes.  The Lenco is certainly good value.   Rgds,  Hugh

Hello Hugh. I don't know how fast they are but the Lenco's and Minnkota trim tab actuators are probably similar in speed. I seem to remember the 2-1/2 inch stroke on the Minnkota's was 1 inch per second.

Typically the more powerful they are the higher the gearing and slower speed.

After dis-assembling the Firgelli actuators I have to investigate how oil compensation might be accomplished, I saw how cheaply they are made. Not even close to the Lenco's brochure as to quality.

At $259 or so, they seem like a fairly inexpensive and powerful actuator.
