Airtac MIJ Adjustable Cylinder MIJ20X225-20
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X225-20 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 225mm 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 MIJ20X225-20
Dialing in a precise forward end position on-site is effortless with this stainless steel round-body mini cylinder. A built-in external stop screw shortens the extend stroke by up to 20 mm, allowing you to tune the usable forward travel down from the 225 mm nominal length without swapping hardware. The retract stroke remains full length, and the screw functions purely as an end-position adjuster rather than a mid-stroke lock.
Built with a Ø20 mm bore and an M8x1.25 male rod thread, it delivers 157 N of push force at 0.5 MPa. This translates to a safe working load of roughly 94 N, or about 8 kg of vertical lift with a 2:1 safety margin. The riveted stainless barrel and rod resist mild corrosion and washdown environments. Conforming to the ISO 6432 mounting interface, it drops directly into standard mini brackets and clevises. Air connects via a 1/8" port.

Where the Airtac MIJ Adjustable Cylinder MIJ20X225-20 Is Used
Diverting Gate Adjustment
Fine-tune a sorting gate's extend position by up to 20 mm to accommodate different package sizes on the fly, using the 157 N push force to swing the diverter reliably.
Staged Feed Pusher
Push parts to a varying downstream stop without changing the cylinder, trimming the 225 mm extend stroke to dial in exact placement during product changeovers.
Carton Flap Tucking
Tuck varying carton flaps precisely by adjusting the forward end position on-site, letting the fixed TPU bumpers absorb the final impact without crushing the board.
Is the Airtac MIJ Adjustable Cylinder MIJ20X225-20 the Right Cylinder?
When sizing this actuator, consider the next bore down (Ø16, 100.5 N push @0.5 MPa) for lighter duties, or step up to the Ø25 (245.3 N push @0.5 MPa) if your load exceeds the 94 N safe working threshold. The 20 mm adjustment window is highly useful for absorbing mechanical tolerances or matching multiple stop points during machine changeover using a single part number. Remember that the stop screw sets the end position but does not hold the load on air loss; the piston will drift if pressure drops. For suspended loads, integrate an external rod lock or pilot check valve.
This SKU is not equipped with a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors for position detection—order the -S variant if switching is required. Mounting options include LB foot, FA flange, and TC trunnion, along with CA, U, R, or CM back covers. Note that the SDB pivot block is not available on this adjustable-stroke series. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.
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 MIJ20X225-20 FAQ
This Ø20 mm bore cylinder uses a 1/8" air port. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. 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, letting you set the exact forward position while the retract stroke remains full length. This SKU lacks a magnet and cannot take position sensors; the -S variant is required for CMSG, DMSG, or EMSG switches.
