Thanks billy for the link! I think I have it solved! I used the square lead screw because it seems the most efficient.. The axial torque seems to be .184 kg*cm.. Seems low but math doesn't lie! Hopefully it works..billy_joule said:
Oh heck! I didn't factor that in! It'll just be silicone on polyethylene.. sound be easy to find..billy_joule said:

A lead screw is a type of mechanical screw that is used to convert rotational motion into linear motion. It consists of a threaded shaft (the screw) and a nut with matching threads. When the screw is rotated, the nut moves along the threads, causing linear motion.
Psi (pounds per square inch) is a unit of measurement for pressure. In the context of a lead screw, the amount of psi applied to the screw can affect the amount of torque required to rotate it. Higher psi means there is more pressure on the screw, resulting in a higher torque requirement.
The torque on a lead screw based on psi can be affected by a few different factors. These include the diameter and pitch of the screw, the coefficient of friction between the screw and nut, and the amount of pressure or force being applied to the screw.
Yes, the torque on a lead screw can be calculated by multiplying the pressure (in psi) by the effective area of the screw (determined by the screw's diameter) and the coefficient of friction. The resulting value is the torque required to overcome the pressure on the lead screw.
To minimize the torque required on a lead screw, you can try reducing the pressure or force applied to the screw, using a screw with a larger diameter or smaller pitch, and choosing a lower coefficient of friction between the screw and nut. Additionally, ensuring proper lubrication and maintenance of the lead screw can also help reduce the required torque.
