The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 60mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Dial in a precise 40 to 60 mm forward stop on site with the AirTAC MICJ40X60-20S, a stainless-steel round-body mini cylinder featuring a 20 mm extend-stroke adjuster. The external screw trims the extend end position without swapping hardware, while a needle-set variable air cushion at both ends soaks up high-speed shock to protect your tooling.
Driven by a 1/4 inch port and a 16 mm rod, this double-acting actuator delivers 628.3 N of push force at 0.5 MPa, yielding a computed safe working load of roughly 377 N or a 32 kg vertical lift with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors, and the stainless construction resists mild washdown corrosion.

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 Ø40 bore is a larger, non-ISO-6432 size.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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.
Delivers 628.3 N to seat components, using the 20 mm extend stop to dial in the exact crush depth while the air cushion absorbs the high-speed impact.
Handles payloads up to 32 kg safely, trimming the extend position to align with passing cartons without over-travel shock.
Stainless barrel and rod resist mild corrosion while applying consistent sealing pressure, with the needle cushion decelerating the stroke end.
For lighter pushes, the MICJ32 offers 402.2 N at 0.5 MPa, whereas this 40 mm bore provides 628.3 N; no larger standard MICJ bore exists. Choose this model when you need to set a fast, exact extend position and rely on the dual-end air cushion to decelerate the load smoothly. Remember the stop screw sets the end position but does not lock mid-stroke, so fit an external rod lock or pilot check valve if you must hold a load on air loss.
Mount using LB foot, FA flange or TC trunnion brackets, as the SDB pivot block is not offered on this adjustable variant. The included -S magnet enables position sensing with CMSG, DMSG or EMSG switches.
Quick checklist
It features a 1/4 inch port and delivers 628.3 N push / 527.8 N pull at 0.5 MPa, and 879.6 N push / 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on site, and a needle-set variable air cushion at both ends decelerates the piston near stroke end. The -S magnet allows CMSG, DMSG and EMSG sensors to track position.
