Beyond the press | World First Working Transparent Hydraulic Cylinder? @Beyondthepress | Uploaded January 2019 | Updated October 2024, 1 week ago.
Our workshop got pretty demanding task of manufacturing transparent hydraulic cylinder that actually works and can take pressures up to 70 bars that generates over 2 tons of force. With some special tooling guys were able to machine acrylic cylinder tube for cylinder. I didn't have time to film machining part but here is link to older acrylic machining video youtu.be/a4egfD3c8eM
