0.4 Inch 0.4" Stroke Mini Linear Actuator 12V 42.2lbs/188N Electric Micro Linear Actuator Speed 0.2"/sec with Mounting Brackets,for Robotics,Home Automation,Item Weight 0.082lbs

Great for a tractor project i made, little light duty for my task but would work wonderful for smaller tasks

Works as intended. Cheaper materials and parts, but you get what you pay for.

If you think your reviews four stars, why don't you rate it yourself. I bought this object and it does not function but it looks like it could if it had the right software in the background but doesn't have no USB port to hook up to the computer. You got to have a wiring system that you do yourself or just shove it up to a wiry adjust. Water was used and not paid for by Amazon, or it's use.

If you are just needing 2" more stroke then this is what you need! Works as advertised!

Excellent compact linear actuator smooth operation. It will work very good for opening and closing door on spreader.

I like the item, but it's slower than I had hoped. It has significantly more torque than I expected. My item's stroke was only .804", not the advertised .83".

I would order again

Works very well and nice price! Would recommend for experimenting with automatic motion control.
