Airtac MIJ Adjustable Cylinder MIJ20X100-100S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X100-100S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 100mm 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 MIJ20X100-100S
Dial in a precise forward end position on-site with the AirTAC MIJ20X100-100S, a round-body stainless steel mini cylinder featuring a 100 mm adjustable extend stroke. An external stop screw lets you shorten the forward travel anywhere from 0 to 100 mm, allowing one part number to cover multiple stop distances without swapping hardware. The retract stroke remains full length, and the screw simply sets the end point rather than acting as a mid-stroke lock.
Built with a stainless-steel barrel and piston rod for mild corrosion and washdown resistance, this double-acting actuator delivers 157 N of push force at 0.5 MPa. It uses a 1/8" air port and an M8x1.25 male rod thread. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for position confirmation. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N or lifts about 8 kg vertically with a 2:1 margin.

Where the Airtac MIJ Adjustable Cylinder MIJ20X100-100S Is Used
Variable Stroke Diverter
Route packages of differing sizes on a belt by dialing the diverter arm out 0 to 100 mm, utilizing the 157 N push force to cleanly deflect parcels without overextending.
Tolerance Take-Up Press
Clamp assemblies with a safe working load of 94 N while using the external stop screw to compensate for part thickness variations, ensuring repeatable contact pressure.
Adjustable Staging Pusher
Feed components to varying stop points in a staging lane; the 8 kg vertical lift capacity easily handles lighter trays, and the stop nut allows rapid changeover between product runs.
Is the Airtac MIJ Adjustable Cylinder MIJ20X100-100S the Right Cylinder?
When sizing this 20 mm bore actuator, compare it against adjacent bores: a smaller MIJ16 yields 100.5 N push at 0.5 MPa, while a larger MIJ25 provides 245.3 N. The 100 mm adjustment window is highly useful for machine setup and absorbing mechanical tolerances, letting you fine-tune the stroke without machining spacers. Remember that the fixed TPU bumper pads only decelerate the stroke end; the cylinder will drift and cannot hold a load on air loss, so add an external rod lock or pilot check valve if you need true position holding.
This model conforms to the ISO 6432 mounting interface for standard mini brackets and clevises. You can use LB foot, FA flange, or TC trunnion mounts, but the SDB pivot block is not available on this adjustable variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for electronic or reed 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 MIJ20X100-100S FAQ
This 20 mm bore cylinder uses a 1/8" air port and provides 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100 mm on-site so you can set the exact forward end position; the retract stroke remains full. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, and EMSG sensors, and the stainless steel build resists mild corrosion.
