Airtac MICJ Adjustable Mini Cylinder MICJ20X75-30
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X75-30 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 75mm 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 MICJ20X75-30
Dial in the forward stop on-site without swapping cylinders: the MICJ20X75-30 uses an external screw to shorten the extend stroke by up to 30 mm, giving a usable forward range of 45-75 mm while retract remains full. This double-acting, stainless-steel round-body mini cylinder pairs that set-position flexibility with an adjustable air cushion at both ends to soak up high-speed shock.
Built with a corrosion-resistant stainless barrel and Ø8 rod, it drops into standard ISO 6432 mini-cylinder brackets. At 0.5 MPa it pushes 157 N and pulls 131.9 N, yielding a safe working load around 94 N or a 2:1 vertical lift of roughly 8 kg. The 1/8" port and M8x1.25 male thread match the Ø20 bore standard. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-30 Is Used
Light Pressing Stops
Trim the 30 mm extend screw to set exact 60 mm pressing depths on small assemblies, using the 157 N push force to seat clips without overshooting.
Package Diverter
Tune the forward stroke to clear varying box widths on a line, while the dual air cushions absorb the high-speed impact of rapid diverting moves.
Film Cut-off
Dial the extend end to a precise 50 mm to cut wrapping film cleanly, letting the adjustable cushion decelerate the blade before it hits the mechanical stop.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-30 the Right Cylinder?
Size both ways against your force needs: stepping down to a Ø16 bore drops the 0.5 MPa push force to 100.5 N, while moving up to a Ø25 bore raises it to 245.3 N. Choose this Ø20 when your payload is around 8 kg and you need to tune the extend endpoint on the fly. The external screw sets the end position but is not a mid-stroke lock; the air cushion only decelerates near the stroke end. If you need to 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 on this adjustable variant), and select back covers CA, U, R or CM. Because this specific SKU has no -S magnet, it cannot accept position sensors; order the -S variant if you need 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 MICJ20X75-30 FAQ
This Ø20 mm bore cylinder has 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 stroke by up to 30 mm (usable range 45-75 mm); retract stays full. A needle-set adjustable air cushion at both ends decelerates the piston near stroke ends but does not act as a lock. The cylinder drifts on air loss, so use an external rod lock to hold a load. This non-S SKU has no magnet for sensors.
