He is asking about a hyd/air actuator, but is pointing to a cable holder. Just what is the real question. Please use a good camera, and no cell phone pic.

What I thought was a hyd cyl is actually a CNC mandrel used for gripping and turning metal tubing for bending. Although there are some hyd cyl for gripping and bending. As far as the original post, what is the question?

The whole machine or a particular part. Basically, the machine uses a computer program to bend a pipe to your specifications. You and the computer will make up a program to cause the machine to take a pipe/tube, and place it in a certain position, bend it at a certain angle and do this until the pipe is bent to your specifications. There are many different parts that work together to accomplish this. Is thee a question about individual parts?
