Airtac MIJ Adjustable Cylinder MIJ20X160-20
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X160-20 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 160mm 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 MIJ Adjustable Cylinder MIJ20X160-20
Dialing in a precise forward end position is effortless with this stainless-steel round-body mini cylinder, because an external stop screw lets you trim the extend stroke by up to 20 mm directly on the machine. As a double-acting actuator with a 160 mm nominal stroke, it yields a push force of 157 N and a pull force of 131.9 N at 0.5 MPa, making it robust enough for mid-range positioning tasks.
Built with a 20 mm bore, an Ø8 mm piston rod, and a 1/8" port, the unit conforms to ISO 6432 mounting dimensions for straightforward bracket interchange. The stainless barrel and rod shrug off mild washdown environments. For sizing, this bore provides a safe working load of roughly 94 N, translating to a vertical lift capacity of about 8 kg with a 2:1 safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ20X160-20 Is Used
Staged Feed Ejection
Uses the 20 mm extend trim to push parts of varying widths off a belt without repositioning the cylinder, relying on its 157 N push force to clear jams.
Changeover Stop Blocks
Allows operators to dial in the exact forward stop for different product runs on a machining fixture, absorbing setup tolerances on the fly.
Variable Flap Folding
Fine-tunes the folding arm extension for different carton depths, using the 131.9 N pull force to retract the arm cleanly between cycles.
Is the Airtac MIJ Adjustable Cylinder MIJ20X160-20 the Right Cylinder?
When sizing this actuator, the 20 mm bore sits comfortably between the smaller Ø16 (100.5 N push @0.5 MPa) and the larger Ø25 (245.3 N push @0.5 MPa). Choose this model when your application demands approximately 94 N of safe working force and requires on-site tolerance take-up, as the 20 mm adjustment window allows one part number to cover several slightly different forward stops without swapping cylinders.
Keep in mind the fixed TPU bumper pads only decelerate the piston near the stroke end; they do not function as a mid-stroke lock or brake. If your load must be held during air loss, install an external rod lock or pilot-operated check valve. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable), and note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.
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 MIJ20X160-20 FAQ
At 0.5 MPa it provides a 157 N push and 131.9 N pull. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8".
An external stop screw shortens the extend stroke by up to 20 mm, giving a usable forward range of 140-160 mm; the retract stroke remains full. The screw only sets the end position and does not lock the piston mid-stroke, so the cylinder drifts on air loss. This SKU has no magnet and cannot take sensors.
