Hello lemgineers!
I’m working on designing a claw that can be operated underwater. The plan is to use a linear actuator in a waterproof housing. The main issue is allowing the shaft to slide through without causing a leak. What’s the best way to go about this?
If the travel distance of the rod is fairly limited, you can use a corrugated boot.
Otherwise, maybe a gland seal with positive air pressure on the dry side?
