About the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-50
Dial in a precise forward stop on-site with the AirTAC MICJ20X200-50, a stainless-steel round-body mini cylinder that lets you shorten the extend stroke by up to 50 mm without swapping hardware. Driven by a 1/8" port and an Ø8 rod with an M8x1.25 male thread, it delivers 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or an 8 kg vertical lift with a 2:1 margin.
Beyond setting the end position, this double-acting ISO 6432 unit features an adjustable air cushion at both ends to soak up high-speed shock before impact. The stainless barrel and rod resist mild corrosion and washdown. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to the -S variant.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-50 Is Used
Package Diverter Gate
Shifts a sorting flap precisely on a conveyor. The 50 mm extend trim sets the exact deflection angle, while the air cushion absorbs the impact of fast 8 kg carton flows.
Film Roll Tensioner
Feeds packaging material forward and dials in the slack. The stainless build handles light washdown, and the adjustable forward stop prevents roll tearing.
Component Push-off Station
Ejects machined parts from a fixture at speed. The needle cushions arrest the 200 mm stroke smoothly, protecting the M8x1.25 rod thread from end-of-stroke shock.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X200-50 the Right Cylinder?
When sizing this 20 mm bore, step down to an MICJ16 (100.5 N push @0.5 MPa) for lighter loads, or step up to an MICJ25 (245.3 N push @0.5 MPa) if you need more thrust. The 50 mm extend adjuster and dual needle cushions shine in fast set-position moves where you must tune the forward stop and decelerate the mass smoothly. Mount via LB foot, FA flange, or TC trunnion, plus CA, U, R, or CM back covers, but omit the SDB pivot-block as it is unavailable here.
Remember the stop screw sets the end position but acts as no mid-stroke lock. If air pressure drops, the piston drifts because the cushion only decelerates near the stroke end. Use an external rod lock or pilot check valve to hold a suspended load safely.
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 MICJ20X200-50 FAQ
This 20 mm bore cylinder uses a 1/8" port. 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 maximum of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm, and a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. This SKU has no magnet for sensors, and the cushion is not a brake—the piston will drift on air loss, so use a pilot check valve for load holding.
