About the Airtac MIJ Adjustable Cylinder MIJ20X300-100S
Dial in a precise forward end position on-site with the AirTAC MIJ20X300-100S, a double-acting round-body mini cylinder featuring a 100 mm extend-stroke adjustment window. You can trim the forward travel anywhere between 200 and 300 mm via the external stop screw, allowing a single part number to cover multiple stop distances without changing the hardware. Retract travel remains at the full 300 mm. Built with a stainless-steel barrel and piston rod, this riveted construction handles mild corrosion and washdown environments better than standard carbon steel units.
At 0.5 MPa, the Ø20 mm bore generates 157 N of push force and 131.9 N of pull force, yielding a safe working load of roughly 94 N or a vertical lift capacity of about 8 kg with a 2:1 margin. The 1/8" air port and M8x1.25 male rod thread match standard mini-cylinder interfaces, and the unit conforms to ISO 6432 mounting dimensions for easy bracket interchange. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing.

Where the Airtac MIJ Adjustable Cylinder MIJ20X300-100S Is Used
Changeover Diverter
Set the exact extend stop between 200 and 300 mm to deflect packages of varying sizes on a packaging line without physically swapping the cylinder.
Tolerance Take-Up Press
Use the 157 N push force to seat light components, dialing the external screw inward by a few millimeters to compensate for part thickness variations.
Staged Carton Feed
Push corrugated cartons into a labeling station with a safe working load of 94 N, adjusting the forward end position to match different box formats on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ20X300-100S the Right Cylinder?
When sizing this actuator, check your force margins both ways: stepping down to a Ø16 bore drops the 0.5 MPa push force to 100.5 N, while moving up to a Ø25 bore increases it to 245.3 N. The 100 mm adjustment window is highly useful for taking up mechanical tolerances during setup or staging feeds across changeover jobs, saving you from stocking multiple stroke lengths. Remember that the stop screw only trims the extend end point—it is not a mid-stroke lock.
This cylinder does not hold position on air loss; the piston will drift if pressure drops, so add an external rod lock or pilot-operated check valve for suspended loads. Deceleration relies on fixed TPU bumper pads rather than an adjustable air cushion. For mounting, you can use LB foot, FA flange, or TC trunnion brackets along with CA, U, R, or CM back covers, but note that the SDB pivot block is not available on this adjustable 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 MIJ20X300-100S FAQ
This double-acting cylinder uses a 1/8" air port and an M8x1.25 male rod thread. It delivers 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 stop screw shortens the extend stroke by up to 100 mm on-site, letting you set the forward end position between 200 and 300 mm while retract remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors, and the stainless steel build resists mild washdown corrosion.
