Hey everybody:

I am planning to buy a linear actuator. I am not familiar with them. My question is: If i apply voltage to it and extended to a desired position and then remove to supplied voltage, does it lock in that position even if i try to contracted?

Second question is i want to make sure this actuator when one polarity is applied then it extends and if i apply the reverse polarity then it contracts.
Am i correct?

I appreciate all your information.

I used one from Saginaw with a 40" stroke. It stopped moving, but had no brake applied with power off.

Find out who makes it and get the specs from the manufacturer.

10:1 gear ratio suggest the actuator would at least be difficult to move when the power was off, but is no guarantee of "locking in place."
