Airtac MICJ Adjustable Mini Cylinder MICJ20X175-30
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X175-30 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 175mm 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 MICJ20X175-30
Dial in a precise forward stop on-site with the AirTAC MICJ20X175-30, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 30 mm via an external screw (usable forward range 145-175 mm). It pairs this settable end-position with a needle-adjustable air cushion at both ends to soak up high-speed shock, giving you simultaneous position control and impact management. The double-acting bore delivers 157 N of push force at 0.5 MPa, translating to a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin.
Built with a riveted stainless barrel and an 8 mm rod, it resists mild corrosion and washdown while conforming to the ISO 6432 mounting interface for standard mini brackets. It uses a 1/8" port and an M8x1.25 male rod thread. Note that this specific SKU lacks a magnet and cannot host CMSG/DMSG/EMSG sensors; the stop screw and air cushions only decelerate near stroke end, so fit an external rod lock if you need to hold a load on air loss.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X175-30 Is Used
Tunable Clamping Press
Adjusts the 30 mm extend stop to clamp delicate 8 kg assemblies precisely, while the dual air cushions absorb the impact of rapid 175 mm strokes.
Dynamic Transfer Diverter
Sets an exact forward reach of 145-175 mm to deflect light goods on a belt, using the 157 N push force and needle cushions to brake the high-speed extend.
Carton Flap Folder
Folds packaging flaps at speed, relying on the stainless construction for washdown resistance and the adjustable stroke to fine-tune the fold depth.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X175-30 the Right Cylinder?
When sizing this 20 mm bore, step down to the MICJ16 (100.5 N push @0.5 MPa) for lighter probes, or up to the MICJ25 (245.3 N push @0.5 MPa) if your payload exceeds the 8 kg safe vertical lift. The 30 mm extend adjuster is ideal for fast set-position moves where you need to tune the forward stop without swapping cylinders. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant). Because this non-magnet SKU cannot take a sensor, choose the -S version if your sequence requires CMSG/DMSG/EMSG detection.
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 MICJ20X175-30 FAQ
This double-acting 20 mm bore cylinder uses a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa.
An external screw shortens the extend end by up to 30 mm (retract stays full), while needle valves adjust the air cushions at both ends to decelerate high-speed moves. This SKU has no magnet for sensors, and the cylinder does not hold position on air loss—use an external rod lock for that.
