Description
Overview
The ControlAir Mini Might Rolling Diaphragm Air Cylinders deliver the same virtually friction-free performance as ControlAir’s larger rolling diaphragm cylinders in an extremely compact package. Utilizing ControlAir’s unique rolling diaphragm technology, Mini Mights eliminate stiction and blow-by leakage to provide exceptional sensitivity, outstanding repeatability, and precise linear motion for space-constrained applications.
Unlike conventional miniature cylinders that rely on sliding seals, Mini Mights use a rolling diaphragm that virtually eliminates friction throughout the stroke. The result is smooth, accurate movement with low hysteresis, making these cylinders ideal for precision force control, positioning, and OEM equipment where reliable, repeatable pneumatic motion is essential.
Available in MM-1 and MM-2 configurations, Mini Might cylinders feature a compact aluminum body, reinforced nitrile rolling diaphragm, chrome-plated steel rod, and sintered bronze bearing for long service life and dependable performance in demanding industrial environments. Both models provide a 0.70-inch stroke with a maximum operating pressure of 125 psig.
