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?
We actually did start out with an accordion/bellows design, but found that the flexibility of the material alone was more than sufficient to handle the required distance of travel on the actuator piston!
