NORJIN 12V Mini Electric Linear Actuator 0.8" Stroke, 32N/7.2lbs, Speed 15mm/s, Linear Motion Actuators with Mounting Brackets, for Robotics, Cabinets, Home Automation

Good cheap actuator for my humanoid lab work

Works great. Very powerful in a small package

I tried it it extended and retracted 4 to 5 times and it quit stayed extended I’m sure it will work for what I want to do .I like to try another for my application

I purchased the 1.2” version. It is quite compact and looks to be well made. The linear motion is smooth and consistent with endstop limit switches at both ends. Power consumption is 65mA under no load. My use-case is very light duty (opening an outdoor gate latch once a day), so won’t be anywhere approaching its limits. Shall see how it holds up over time.

Nice compact little actuator. This is probably typical of actuators, but it takes a little time to spin down when you disconnect the power. If you need precise movement you need something more like a step motor. My use is to adjust the throttle on a snow blower. full throttle and idle will be easy, but something in between will be hit or miss.

i dont think it will last very long, already sounding worse after 50 actuations

I bought this to power a mockup of a focus slider that I designed for macro photography. When I had the slider working I brought out this actuator, only to discover that no matter what power source I tried to use, it appeared to be completely dead. Why disappointment turned to horror as I checked the date of purchase and saw that 30 days had just passed and I would be unable to finish my project. I don't want to buy another actuator. The frustration caused me to abandon my focus slider prototype months ago.

I’ve extended and retracted it 50 times, and it appears to work flawless.
