The AirTAC MIJ Adjustable Cylinder MIJ25X220-20S is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø25mm bore and 220mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface fits standard ISO 6432 mini-cylinder mounting interfaces.
Dial in a precise forward end position on-site with the AirTAC MIJ25X220-20S, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 20 mm, providing a usable forward range of 200 to 220 mm without swapping parts. The retract stroke remains full length.
This Ø25 mm unit conforms to the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port with an M10x1.25 male rod thread. The stainless barrel and rod resist mild corrosion and washdown environments. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG sensors for position detection. Fixed TPU bumper pads decelerate the piston at the stroke ends across a 30-800 mm/s speed range.

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 components down a line at 245.3 N, using the 20 mm extend adjustment to dial in the exact ejection distance for varying product widths.
Folds packaging flaps on demand; the external stop screw fine-tunes the forward fold position to prevent crushing, handling about 12.5 kg vertical lift safely.
Acts as an adjustable mechanical stop for machining fixtures, allowing operators to switch between two forward end positions on the 220 mm stroke without changing cylinders.
When sizing this 25 mm bore, stepping down to a 20 mm MIJ drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. The 20 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering several stop positions with one part number. The stop screw sets the extend end position but acts purely as an end stop, not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available), and use CMSG/DMSG/EMSG switches made possible by the -S magnet.
Quick checklist
The theoretical maximum force is 50 kgf at 1.0 MPa. This bore uses a 1/8" air port and a 10 mm rod with an M10x1.25 male thread.
An external stop screw shortens the extend stroke by up to 20 mm on-site, giving a usable forward range of 200-220 mm; the retract stroke remains full. The -S suffix means a piston magnet is built-in, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
