Rodless Cylinder
Pneumatic rodless cylinders working?
That is a very cryptic question, but they do manufacture pneumatic cylinders where the piston has a very strong magnet which moves back and forth with the piston. A sleeve outside the cylinder has a magnet too, and this couples the sleeve to the piston, transferring motion. The coupling of the magnets can be anywhere from a few pounds to over 100 pounds determined by the diameter and sizes of the magnets. They can be quite strong actually.
Another system has a loop (metal band) that attaches to the moving piece and the piston with seals on each end of the air chamber. The magnetic design requires no seals.

The 2009 Report on Non-Aerospace-Type Linear Pneumatic Fluid Power Cylinders with Bore Size of at Least 1-1/2 Inches Excluding Rodless, Aluminum, and Steel Types: World Market Segmentation by City $795.00 This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a “borderless world”, cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in… |
