off, not as quick as the rating suggests   I use a lot of linear actuators in different projects, and I don't always need the 250-pound ones. Many offer pound-for-pound force capability, but at the cost of bulkiness. These tiny machines can only handle about 4 pounds, but they're quick (about 1 cm (1/2") per second) and quiet. They're easier to fit into tight spaces because of their small size and the fact that the motor runs parallel to the drive axis rather than on the side like most larger devices. br>br>Like most linear actuators, these will stop automatically when they reach the end of their travel, but this is done in a unique way. Rather than end-to-end, When a travel limit switch with bypass diodes is activated, the motor is turned off due to an internal current sensor. This means that if the actuator collides with something else before reaching its normal end-point, it will stop working. The motor will be turned off after a certain number of strokes. The power must be turned off and on again in order to resume operation. applied, or, more commonly, reversed in order to go in the opposite direction br>br>This method ensures that if something unexpected occurs, such as a mechanism jamming, the actuator will not continue to push until it breaks or burns out. Furthermore, depending on how your apparatus is designed, you can have the actuator reach a mechanical limit and have it stop automatically without the use of limit switches - So you won't have to do any more wiring or fabrication. Because the shutdown is electronic, the actuator continues to draw a small amount of current (around 10 mA) even after it has been turned off. If you're a person with a lot of power, this is a good place to start. If you have a sensitive system, you may want to find a different way to ensure that the actuator is properly disconnected after it has completed its motion. br>br>The units appear to be well built. I've never dismantled one, but it appears that I could - The motor housing cover is secured with screws and can be removed for lubrication if necessary. The clevis mounts shown in one of the pictures were not included with the units I purchased. In addition, the speed is nowhere near as fast as the title suggests - It's closer to 0"/sec than 2"/sec. 6"/sec. I deducted a star for these two reasons, but I like the actuators and the price is reasonable in comparison to other items, so I'd probably buy them again.

Because of how small it is and how much power it produces, it came as a bit of a shock. In a prop I was working on, I needed a way to tilt a 10 pound object. It was able to do so in a timely manner. It moves quickly and has built-in limit switches that cut off power to the motor when it reaches the end of its range of motion. When stopped, it will stay put, but if enough weight is applied, it will move. I'm guessing 15 to 20 pounds. 20lbs. It's not silent, but it's not too loud for the amount of work it does in a short period of time; overall, I'm pleased with it and plan to use it in future projects.

  After a door lock solenoid failed due to vibration, I ordered this 1 inch actuator to use as a choke on a generator that I'm installing on a semi truck. The relay board wiring that I used to extend and retract the cylinder is shown in the photo. A single wire generator start is also available, which can be used to start the generator using the solar battery system and/or Alexa. br>br>I'm delighted that this actuator performs so well!.

I'm not sure what brackets to use for this. I intend to purchase two more, but having brackets would reduce my time in half.

I used this actuator for a purpose it was probably not designed for, but it worked perfectly. This actuator, along with a mount and a throttle cable, was used to convert a manual throttle on a machine to an electric throttle. I was able to adjust the throttle from afar using a button/switch, which solved the problem perfectly!.

It's what I use to open and close my RV's black water gate valve.
