The AirTAC MICJ Adjustable Mini Cylinder MICJ40X75-75 is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 75mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Dial in the forward stop on site without swapping cylinders: the MICJ40X75-75 uses an external screw to shorten the extend end by up to 75 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. This double-acting round-body mini cylinder features a stainless-steel barrel and rod for mild washdown resistance, operating at speeds of 30-800 mm/s via a 1/4" port.
Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Pushes heavy cartons at high speed on a packaging line, using the 75 mm extend trim to dial the exact push distance while the dual air cushions absorb the impact at stroke end.
Acts as a heavy-duty stop gate for loaded pallets, tuning the extend position on site to match pallet depth and using the adjustable cushions to survive fast impacts.
The 75 mm extend trim and dual air cushions shine in fast set-position moves where you must tune the forward stop and decelerate the impact without changing the hardware.
Because a plain cylinder drifts on air loss, the stop screw and cushions only set the end position and decelerate—they do not lock mid-stroke. Use an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB is not available), and select the -S variant if you need position sensing.
Quick checklist
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm, and needle valves tune the adjustable air cushions at both ends to decelerate high-speed impacts. This SKU has no magnet for sensors. The cushions and stop screw do not lock mid-stroke; the piston drifts on air loss, so use an external rod lock for held loads.
