Airtac MIJ Adjustable Cylinder MIJ8X20-20
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X20-20 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 20mm stroke, M5×0.8 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 MIJ Adjustable Cylinder MIJ8X20-20
Dial in a precise forward end position on-site with the AirTAC MIJ8X20-20, a round-body stainless steel mini cylinder. An external stop screw shortens the extend stroke by up to 20 mm, letting you absorb setup tolerances or cover multiple stop points from a single part number without swapping hardware. Retract remains full stroke. The Ø8 mm bore runs on an M5x0.8 port and delivers 25.1 N of push force at 0.5 MPa.
Built with a riveted stainless barrel and rod, the unit resists mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets. This SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 15 N (about 60% of the 0.5 MPa push), which translates to lifting around 1.3 kg vertically with a 2:1 margin.

Where the Airtac MIJ Adjustable Cylinder MIJ8X20-20 Is Used
Micro-actuation trimming
Use the 20 mm extend adjuster to fine-tune the forward reach of a 25.1 N probe or lightweight pick-head, hitting exact contact points without machining new spacers.
Small part staging
Push delicate electronic components into a test nest at a safe 15 N working load, using the external screw to dial in the exact feed distance for each product changeover.
Lab positioning stops
Set repeatable forward stops for fluid sampling or micro-dispensing heads in washdown-prone labs, relying on the stainless construction and fixed TPU bumpers to soften stroke ends.
Is the Airtac MIJ Adjustable Cylinder MIJ8X20-20 the Right Cylinder?
This Ø8 bore provides the smallest standard thrust in the range (25.1 N push at 0.5 MPa). If your payload needs less force, no smaller MIJ bore exists; stepping up to a Ø10 yields 39.3 N push. The 20 mm adjustment window is highly useful for taking up mechanical tolerances during changeovers. Remember that the stop screw sets the end position but acts as no mid-stroke lock; the piston drifts on air loss. For held loads, install an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here). Choose the -S variant if you need position sensing.
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 MIJ Adjustable Cylinder MIJ8X20-20 FAQ
It features an M5x0.8 port. At 0.5 MPa it pushes 25.1 N and pulls 18.8 N; at 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on-site; retract remains full. The screw is not a mid-stroke lock, and the piston drifts on air loss. This SKU has no magnet, so it cannot take sensors; the -S version adds magnet compatibility.
