About the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-75S
Dial in a precise forward stop on-site with the AirTAC MICJ20X200-75S, a stainless-steel round-body mini cylinder featuring a 75 mm extend-stroke adjuster. The external screw trims the forward end position from 200 mm down to 125 mm without swapping hardware, while the needle-set adjustable air cushion at both ends soaks up high-speed shock. Retract remains at the full 200 mm. Driven by a 1/8" port and an Ø8 mm rod, this double-acting ISO 6432 unit pushes 157 N and pulls 131.9 N at 0.5 MPa.
The built-in magnet (-S) supports CMSG, DMSG and EMSG position switches for closed-loop confirmation. Stainless construction resists mild corrosion and washdown environments. For sizing context, it delivers a safe working load of roughly 94 N (about 60% of the 0.5 MPa push force), translating to a vertical lift of approximately 8 kg with a 2:1 safety margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-75S Is Used
Diverting Gate Actuation
Trims the extend stroke up to 75 mm to set the exact gate angle on a sorting line, using the dual air cushions to absorb impact during rapid 157 N routing moves.
Variable Tamping Stop
Adjusts the forward stop down to 125 mm for different carton depths, providing reliable 8 kg vertical tamping force while the cushion prevents end-of-stroke bounce.
Light Press Fit
Dials in a precise 125-200 mm extend position to press light inserts, leveraging the 219.8 N push force at 0.7 MPa and the -S magnet for stroke confirmation.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-75S the Right Cylinder?
When sizing this 20 mm bore, compare it directly against adjacent bores: a 16 mm variant yields 100.5 N push @0.5 MPa, while a 25 mm variant provides 245.3 N. Choose this model when you need 157 N of push force and an on-site extend adjustment of up to 75 mm to fine-tune a set position at speed. The dual air cushions decelerate the piston near stroke ends but do not lock the load; if your application must hold position on air loss, install an external rod lock or pilot-operated check valve.
This SKU includes the -S magnet for CMSG/DMSG/EMSG sensors. Mounting options include LB foot, FA flange and TC trunnion (SDB pivot-block is not available on this adjustable-stroke variant). The male rod thread is M8x1.25.
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 MICJ20X200-75S FAQ
This 20 mm bore cylinder uses a 1/8" port. At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm (usable range 125-200 mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke ends, but this is not a mid-stroke lock. The piston drifts on air loss, so use an external rod lock for load holding. The -S magnet enables CMSG/DMSG/EMSG sensors.
