The AirTAC MIJ Adjustable Cylinder MIJ16X40-20S is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 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 MIJ16X40-20S, a double-acting round-body mini cylinder featuring a 20 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 40 mm nominal length down to 20 mm without changing parts, while retract remains full. This stainless-steel riveted barrel and rod construction resists mild corrosion and washdown environments.
Built to the ISO 6432 mounting interface for standard mini brackets, this Ø16 bore unit pushes 100.5 N and pulls 86.4 N at 0.5 MPa. The M5×0.8 port and M6x1.0 male rod thread ensure straightforward integration, and the included -S piston magnet supports CMSG, DMSG, or EMSG sensors.

| Max (@1.0 MPa) | 18 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.
Shift the forward stop position for different product runs without swapping cylinders, dialing in the exact 20 to 40 mm extend length needed.
Leverage the 5.1 kg vertical lift capacity to push lightweight packaging materials into a fixture, adjusting the end point as wear occurs.
The integrated adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number. The stop screw sets the forward end position but does not function as a mid-stroke lock, so the piston will drift on air loss.
For load-holding requirements, pair this cylinder with an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion styles, plus CA, U, R, or CM back covers (SDB pivot-block is not available on this adjustable variant). Speeds range from 30 to 800 mm/s, and deceleration is handled by fixed TPU bumper pads.
Quick checklist
At 0.5 MPa this double-acting cylinder pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N, with a theoretical max of 20.5 kgf at 1.0 MPa. The air port is M5×0.8 and the male rod thread is M6x1.0.
An external stop screw shortens the extend stroke by up to 20 mm on-site, setting the forward end position without affecting the full retract stroke. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors; a SKU without S cannot take a sensor.
