Looking for high push force micro linear actuators(reddit.com)

I’m aiming to optimize the ratio of (push force)/(actuator diameter), while also minimizing total diameter. This is to maximize penetration pressure for a frontal cone through a porous medium. The best I could find so far are the bullet series from firgelliauto.com. Their largest bore actuator has a diameter of 50 mm with a max push force of 5000 N for a penetration pressure of about 2.55 MPa. 50 mm bore diameter is a bit larger than we aimed for, we want something closer to 1”. Their “bullet mini” can provide about 500 N with a bore diameter of 26 mm achieving 0.94 MPa. Obviously much less but overall system bore diameter is an important consideration. Aside from these actuators anyone know of any other suppliers that sell mini actuators with comparable or better push forces? Mainly looking for off the shelf systems. Pneumatics and hydraulics cannot be considered. submitted by /u/quietbunny99554 [link] [Kommentare]
