Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 150mm 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.

About the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S
Trim the forward stop by up to 75 mm on site without swapping hardware using the AirTAC MICJ20X150-75S. This double-acting round-body mini cylinder pairs that adjustable extend stroke with a needle-set air cushion at both ends, letting you dial in the exact 75-150 mm forward position while soaking up high-speed impact. The stainless-steel barrel and rod shrug off mild washdown environments. Because this is an -S SKU, a built-in piston magnet supports CMSG, DMSG and EMSG sensors for position feedback.
Built to the ISO 6432 mounting interface, the Ø20 mm bore runs on a 1/8" port and an Ø8 mm rod with an M8x1.25 male thread. Delivering 157 N of push force at 0.5 MPa, it provides a safe working load of roughly 94 N, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The external screw sets the extend end point but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve if you need to hold a suspended load.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S Is Used
Adjustable Stop Clamping
Dial in the exact 75-150 mm clamping reach on varying part widths, using the 157 N push force to secure light components while the air cushion softens the end-of-stroke impact.
Gate Diversion Tuning
Set the precise extend position to deflect packages on a conveyor without re-mounting the cylinder, relying on the stainless build for humid washdown zones.
Vertical Lift Dampening
Hoist roughly 8 kg loads through a 150 mm vertical path, using the needle cushions to prevent hard bottoming at high cycle speeds.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S the Right Cylinder?
When sizing this 150 mm stroke unit, step down to the Ø16 bore if your load is under 100 N (it pushes 100.5 N at 0.5 MPa), or move up to the Ø25 bore (245.3 N at 0.5 MPa) if the 157 N push proves marginal. The 75 mm extend adjustment window is ideal for tuning fast approach moves on packaging lines, while the dual adjustable cushions absorb the shock of sudden stops. Mount via LB foot, FA flange or TC trunnion—note that the SDB pivot block is not offered on this adjustable variant. Position sensing requires the included -S magnet; a non-S SKU cannot accept CMSG, DMSG or EMSG switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MICJ Adjustable Mini Cylinder MICJ20X150-75S FAQ
This Ø20 mm bore cylinder features a 1/8" port and delivers 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm (retract remains full), and a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The cushion only softens impact near stroke end—it is not a brake. The cylinder does not hold load on air loss; install an external rod lock or pilot check valve for suspended loads.
