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

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.
Avantages: Le prix est correct, un peu cher, mais il n’ya pas beaucoup de produits sur le marché à comparer. Il fournit une force de 150 lb comme spécification. Il a un retour de résistance et des interrupteurs de fin de course aux deux extrémités, ce qui l'empêche de s'étendre de manière excessive / insuffisante (cela semble évident, mais cette fonctionnalité n'est pas incluse dans tous les actionneurs linéaires à retour!) Les inconvénients: Cet actionneur a des défauts. Tout d'abord, les chapes ne sont pas alignées. Le mécanisme d'actionnement a un angle étrange avec le trou, ce qui rend très difficile la conception autour de celui-ci. La boîte de vitesses à retour n'a pas de lubrifiant, elle fait donc du bruit pendant le fonctionnement. Il semble également beaucoup plus fort que les autres actionneurs linéaires de la même spécification de 150 lb, ce qui n’est certainement pas silencieux. Il ne vient pas non plus avec autre chose, comme des fixations, des vis, des connecteurs comme les autres articles que nous avons commandés précédemment. Globalement, tout va bien si vous avez seulement besoin d’un actionneur puissant capable de pousser / tirer jusqu’à 150 lb, mais ne vous attendez à rien d’exceptionnel.
