12V Linear Actuator, 4" Actuator 14 mm/s High Speed Linear Actuator Waterproof 1000N/220lbs Stroke with Reverse Polarity Switch Controller

Works just like it is supposed to. Using it to steer my trolling motor.

Haven’t had much time to test it. It appears to be of good quality and works as it should.

I have only bench tested the actuator. If it differs in actual use I will update this review.First impressions:Well built for the price, heavy duty brackets and a quality toggle switch. The Up/Down faceplate and waterproof boot for the switch are a nice touch. The shaft does not rotate and has very minimal play.At 12 volts from a benchtop power supply, the actuator draws ~900 milliamps with no load, and ~1.3 amps with a simulated load (me leaning on it).The unit is noisier than expected, though that is subjective. The description mentions the low noise level so I was expecting better. The motor makes a fair bit of the noise, more than the gears, and does not sound smooth. The gear set is plastic, which is expected at this price point. There are gaskets at the housing seams.From the label...Input Voltage: 12DCStroke: 100mmMax Load: 1000NSpeed: 14mm/sDuty Cycle: 10%Waterproof: IP54

Used it for a snowblower chute. Good quality. Comes with a very nice switch plate.

It's not 100% water proof. But I made some improvements and it's better.

Easy to set up. Its very simple and more powerful than I expected. It really gets the job done.

I ordered this for a Box-Lid Project I am working on.The build quality of this is very nice. It's sealed with gaskets and waterproof so can be used outdoors.This is a VERY powerful linear actuator in a small package. It can handle up to 224Lbs of force which is no joke. This is NOT a toy so it's important to know the amount of large forces you will be applying with this.I was not able to take it up to full load as I don't have anything near heavy enough (yet) but from trying to load it down with weight/force I have no reason to doubt it's rated load capacity.The construction is durable all metal. They give you a fair amount of wiring though I will be adding on my own harness.Operation is simple.. polarity one way to extend, reverse the polarity to retract. I tested aprox. 1amp with no load to extend/retract the motor.I like that once it reaches it's stroke limit, it just stops. and I verified it shuts off the motor and doesn't draw any current once it reaches the limit.There are many many uses you could use with this were need a some SERIOUS amount of actuation force in a small 12Volt based actuator.I highly recommend this unit.

This review is for 12V Linear Actuator, 4" Actuator 14 mm/s High Speed Linear Actuator Waterproof 1000N/220lbs Stroke with Reverse Polarity Switch ControllerThis is a well made and powerful 4" linear actuator that has limit switches to shutdown when the ram reaches full extension or retraction. Also included is a DPDT, center off momentary switch to allow up and down motions to be selected easily. A rubber switch cover makes the switch waterproof on the panel side. There are two brackets that connect to the ends of the actuator and allow flexible mounting to obejcts to move.I found the movement to be smooth and it seems to exert roughly the same force through its entire length of travel. The motor draws about 800ma at 13.8V under no load. It is not exceptionally noisy, and seems to meet the 50 dBa specification. I was unable to test with a full load, but partial loads were moved smoothly.I plan to use this as an azimuth actuator for a medium sized yagi antenna for amateur radio satellite operations. If you need a linear actuator with these specs, this is a good value and should meet your needs.This unit seems to be well constructed
