JQDML Upgrade Reciprocating Linear Actuator High Torque 40 lbs, 24V, 120rpm

Solid construction. This thing feels industrial grade. The motor is good - not sure why others are complaining. They even sell replacement motors if this one stalls out. Plenty of torque - just need to raise the rpm a bit on the controller if it’s too low. Can hold plenty of weight and still oscillate. You’ll probably want a mount or a secure surface to screw it into. There are machines which cost several times more than this that do the same thing except use less quality parts and still stall out. Overall this is a great product and good value for your buck, especially if you don’t mind a little DIY.

Insanely low torque; can NOT push against me.

No issues it is working as expected. There were some instructions in the box but really folks? All you need to do is attach the two wire fast-on connectors on the Female power connector pigtail to the two motor terminals. I am not sure way they sent two pigtails, one without the fast-on connectors and one with the connectors. Easier to uses the one with fast-on connector that slid on to the motor power tabs. Be gentle people. The motor tabs are not super strong and could be bent off if to much force is applied. The only adjustment is the position of the shaft to the motor arm and attach the motor arm to the motor shaft. Motor shaft arm position example is if you want a two inch shaft travel just attach the shaft one inch from the motor shaft. Any other travel you want will always be 2X the distance from the motor shaft to the shaft knuckle. Mine came with the shaft travel set for the max travel which I believe is 6 inches. I only needed 3 inches of shaft in/out travel so I set the shaft knuckle 1.5 inches from the motor shaft.

Product works great. Not enough power for what I needed it for. Could have a better connection for the battery to the device.

Old motor was way stronger. Very disapointed.

It doesn't come with a stand unless you want to pay another 100 so I made one which was relatively easy I used a cast iron table removed the top and bolted the liner actuator to it, I've got the suction cup adapter on it which works well if your toy has a strong suction but not so well if it doesn't. I'm giving this 5 stars for the price and capabilities of this model compared to ones that are specifically geared for sexual functions this is cheaper, faster, and has a much longer stroke length than other items I looked at.

attempted to use this as a holiday decoration movement device, for hand waving and such on VERY light items, the reality is this thing try ed to start a fire, its poor quality and bad parts for anyone wondering how the item works or..doesnt in this case if you have it pointed straight up with ZERO load it cant even lift the weight of the main rod at anything less than half power and will stall out under its own weight, on level use it stalls out under the slightest loads, but worse youll think its working untill it just stalls at random gets hot and burns out

I wouldn't say powerful motor. But it does work until it doesent
