The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ32X60-40 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø32mm bore and 60mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Dial in the forward stop without swapping cylinders: the MICJ32X60-40 uses an external screw to shorten the extend end by up to 40 mm on site, giving a usable forward range of 20-60 mm. Retract remains full, and a needle-set variable air cushion at both ends soaks up high-speed shock so you control both the position and the impact.
This round-body stainless steel mini cylinder delivers 402.2 N of push force at 0.5 MPa through a 1/8" port, making it a robust choice for mid-weight automation. The stainless barrel and rod resist mild corrosion and washdown. Note this non-magnet SKU cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches. With a safe working load around 241 N, it lifts about 20.5 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.

| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Set the exact 35 mm extend stop for pressing small bearings, letting the dual air cushions absorb the 402.2 N impact without slamming.
Trim the extend stroke to 45 mm to deflect packages on a line, using the adjustable end position to match varying belt widths perfectly.
Deliver a precise tuck against cartons, tuning the needle cushion to stop the 32 mm bore rod smoothly before it dents the cardboard.
Stepping down, the smaller Ø25 bore provides 245.3 N push @0.5 MPa, which is likely too weak if you need the 402.2 N thrust this Ø32 provides; stepping up to Ø40 yields 628.3 N for heavier loads. Choose this adjustable-stroke model when you need fast set-position moves and want to tune out end-of-stroke shock without adding external shock absorbers.
The stop screw sets the end position but is not a mid-stroke lock, and the air cushion only decelerates near the stroke end. If the application must hold a load on air loss, add an external rod lock or pilot check valve. Mount using LB foot, FA flange or TC trunnion (SDB pivot-block is not available), and select the -S version if you need position sensing.
Quick checklist
This double-acting cylinder has a 1/8" port and an M10x1.25 male rod thread. It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm (retract is full), while needle valves adjust the air cushion at both ends to decelerate high-speed moves. The cushion is not a brake, and the cylinder drifts on air loss; use a pilot check valve to hold a load. This non-magnet SKU cannot take sensors.
