ポテンショメータフィードバック内蔵 リニアアクチュエータ（ストローク 101.6mm 推力 68Kg）

Pros: Price is okay, somewhat expensive but there's not many on the market to compare. It does provide 150lb force as its spec. It has resistance feedback, and also limit switches at the two ends, preventing it from over/under extend (seems obvious but this feature is not included in all feedback linear actuators!) Cons: This actuator has flaws. First of all, the clevises are not aligned. The actuating clevise has a weird angle to the hole, making it very hard to design around it. The feedback gearbox has no lubricant, so it makes noise while running. It also sounds much louder than the other linear actuator of the same 150lb spec, definitely not quiet. It also does not come with anything else, such as mounts, screws, connectors like other items we ordered previously. Overall it is fine, if you only need a strong actuator that push/pull up to 150lb, but don't expect anything exceptional from it.

1 unit I received, was defective. Second unit works perfect
