About the Airtac MIJ Adjustable Cylinder MIJ20X80-20S
Dial in a precise forward end position on-site with the AirTAC MIJ20X80-20S, a double-acting round-body mini cylinder featuring a 0 to 20 mm extend-stroke adjustment window. An external stop screw lets you trim the forward stroke from the 80 mm nominal down to 60 mm, eliminating the need to swap hardware for minor tolerance take-up during setup. The retract stroke remains full length.
Built with a stainless-steel barrel and piston rod for mild corrosion and washdown resistance, this ISO 6432 mounting-interface unit delivers 157 N of push force at 0.5 MPa. That translates to a safe working load of roughly 94 N, or a vertical lift capacity of about 8 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for position sensing, and the 1/8" port ensures reliable airflow for speeds from 30 to 800 mm/s.

Where the Airtac MIJ Adjustable Cylinder MIJ20X80-20S Is Used
Staged Feed Diverter
Trim the 80 mm extend stroke by up to 20 mm to push packages of varying widths onto a secondary conveyor without repositioning the cylinder mount.
Tolerance Take-Up Press
Use the adjustable forward stop to dial in the exact contact point on a 94 N assembly press, compensating for material thickness variations on the fly.
Changeover Sorting Gate
Leverage the 8 kg vertical lift capacity and on-site stroke adjustment to switch a sorting gate between product families quickly, using the magnet for position feedback.
Is the Airtac MIJ Adjustable Cylinder MIJ20X80-20S the Right Cylinder?
When sizing this 20 mm bore, verify your load against the 157 N push force at 0.5 MPa. If you need less force, the 16 mm bore offers 100.5 N push; if your application demands more, step up to the 25 mm bore which provides 245.3 N. The 20 mm adjustable stop is ideal for changeover jobs where one part number must cover several slightly different forward stops.
Remember that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift if air pressure is lost, so add an external rod lock or pilot check valve for holding suspended loads. Mounting options include LB foot, FA flange, and TC trunnion (SDB pivot block is not available on this adjustable variant). Pair the built-in magnet with CMSG, DMSG, or EMSG switches for precise end-of-stroke confirmation.
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 MIJ20X80-20S FAQ
This 20 mm bore cylinder provides a push force of 157 N and a pull force of 131.9 N at 0.5 MPa. At 0.7 MPa, push increases to 219.8 N and pull to 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site, setting the forward end position without affecting the full retract stroke. The -S suffix means it has a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors. The cylinder uses fixed TPU bumper pads for end deceleration.
