Airtac MIJ Adjustable Cylinder MIJ20X100-100
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X100-100 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 MIJ20X100-100
Dial in your forward end position on-site with the AirTAC MIJ20X100-100, a round-body stainless-steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 100 mm. Because retract remains at the full 100 mm, you get one part number covering several different forward stops without swapping hardware. Built with a riveted stainless barrel and Ø8 mm rod, it resists mild corrosion and handles washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets.
At 0.5 MPa this 20 mm bore generates 157 N of push force and 131.9 N of pull, yielding a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin. The 1/8" port and M8x1.25 male rod thread provide standard pneumatic connections. Fixed TPU bumper pads decelerate the stroke ends, operating at speeds from 30-800 mm/s. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ20X100-100 Is Used
Staged Part Ejection
Use the 100 mm extend adjuster to set varying push-off distances for different product lengths on a single conveyor line, leveraging the 157 N push force to clear parts efficiently.
Carton Flap Folding
Fine-tune the forward stroke on-site to fold varying carton sizes without repositioning brackets, relying on the 94 N safe working load to guide flaps smoothly.
Tolerance Take-Up Jig
Absorb mechanical tolerances in machining fixtures by trimming the extend end position up to 100 mm, ensuring the 8 kg vertical lift capacity contacts parts gently without slamming.
Is the Airtac MIJ Adjustable Cylinder MIJ20X100-100 the Right Cylinder?
If your application needs less push, the smaller Ø16 bore delivers 100.5 N at 0.5 MPa; if you need more power, stepping up to the Ø25 bore provides 245.3 N. The 100 mm adjustment window on this unit is ideal for taking up mechanical tolerances or staging feeds during changeovers. Remember that the stop screw only sets the forward end position—it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. You can use LB foot, FA flange, or TC trunnion mounts, but SDB pivot blocks are 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 MIJ20X100-100 FAQ
This 20 mm bore cylinder features a 1/8" port and generates 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, while retract remains full. This SKU has no magnet, so CMSG/DMSG/EMSG sensors cannot be fitted; choose the -S variant for sensing. The stainless build resists mild corrosion.
