We are building four 18" ID x 22" OD cylinders that require 5:1 safety factor at 2500 psi. The material sourced is a 4140 annealed tube with a mill cert yield strength of 62ksi. We have excess material on the ID to bore and hone the cylinder straight, but on the OD the mill specs say it could...
We are trying to come up with a solution to a bushing problem. We have a bushing in an reversing application where a sleeve rotates +/- 15° within a bushing continuously. The sleeve has a 2-3/4" OD for reference.
I need something that will withstand a Velocity of V=210 fpm, P= 2000 psi (force...

We are trying to come up with a solution to a bushing problem. While reviewing a bushing catalog I found that they rate there materials based on the PV values. In the book they state that PV values can be increased by addition of the correct lubricants. I'm also interested in possibly using...
