The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X90-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 90mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.
Trim the forward stop by up to 30 mm on site without swapping cylinders: the AirTAC MICJ25X90-30S is a double-acting, round-body stainless-steel mini cylinder with an adjustable extend stroke and needle-set air cushions at both ends. The external screw shortens the extend end position only (usable forward travel 60-90 mm), while the cushions soak up high-speed shock. A built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing.
Delivering 245.3 N of push force and 206.1 N of pull force at 0.5 MPa, this Ø25 bore unit drops into standard ISO 6432 mini-cylinder brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown environments. For a safe working load, expect about 147 N, or roughly a 12.5 kg vertical lift with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread match the standard Ø25 interface.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Dial in the exact 60-90 mm clamping reach on the fly. The 245.3 N push force secures parts while the needle cushion absorbs the high-speed impact at the end of the modified stroke.
Shift lightweight cartons on a washdown line. The stainless build handles splashes, and the 30 mm extend adjustment lets you reposition the diverting stop without changing hardware.
Pack product into containers by tuning the extend stop to the exact fill height. The dual air cushions decelerate the 12.5 kg tamping load smoothly before the end of travel.
When sizing this unit, compare its 245.3 N push force at 0.5 MPa against adjacent bores: step down to a Ø20 MICJ for 157 N, or step up to a Ø32 for 402.2 N if you need heavier push power. The 30 mm extend adjuster paired with the dual air cushions is ideal for fast, settable-position moves where you must dial in a precise forward stop and control impact at high speed.
Remember that the stop screw sets the end position but is not a mid-stroke lock; the cylinder will drift on air loss, and the cushion only decelerates near the stroke end. For load holding, add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant).
Quick checklist
This double-acting cylinder delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. It uses a 1/8" air port and a Ø10 mm piston rod with an M10x1.25 male thread.
An external screw shortens the extend stroke by up to 30 mm (retract remains full). Needle valves adjust the air cushions at both ends to decelerate the piston near stroke end, though this is not a mid-stroke lock. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG sensors.
