Airtac MIJ Adjustable Cylinder MIJ20X75-40S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-40S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 75mm 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 MIJ20X75-40S
Dial in a precise forward end position on-site with the AirTAC MIJ20X75-40S, a double-acting round-body mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel anywhere from the 75 mm nominal maximum down to 35 mm, absorbing setup tolerances without swapping hardware. The retract stroke remains full length. Built with a stainless-steel barrel and piston rod, it resists mild corrosion and washdown environments.
Delivering 157 N of push force and 131.9 N of pull at 0.5 MPa, this ISO 6432 mounting-interface unit handles a safe working load of roughly 94 N, or about an 8 kg vertical lift with a 2:1 margin. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG position sensing. It uses a 1/8" port, an Ø8 mm rod with an M8×1.25 male thread, and relies on fixed TPU bumper pads to decelerate at the stroke ends.

Where the Airtac MIJ Adjustable Cylinder MIJ20X75-40S Is Used
Staged Product Diversion
Trim the extend stroke by up to 40 mm to push varying box sizes off a belt without repositioning the cylinder brackets, utilizing the 157 N push force for reliable actuation.
Tooling Tolerance Take-Up
Compensate for minor fixture misalignment on machining lines by fine-tuning the forward end position on-site, letting the 8 kg vertical lift capacity handle light tool transfers.
Adjustable Carton Stops
Set precise end stops for different carton depths on a packaging line. The stainless build handles light washdown, while the -S magnet confirms stroke completion via DMSG sensors.
Is the Airtac MIJ Adjustable Cylinder MIJ20X75-40S the Right Cylinder?
When sizing this 20 mm bore, step down to the MIJ16 (100.5 N push @0.5 MPa) for lighter loads, or step up to the MIJ25 (245.3 N push @0.5 MPa) if your thrust requirements exceed the 157 N offered here. The 40 mm external stop screw is ideal for changeover jobs where you need one part number to cover several staged feed distances. Remember the stop screw sets the end position but 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. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable 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 MIJ20X75-40S FAQ
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. It features a 1/8" air port and an M8×1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 40 mm on-site, but the retract stroke remains full length. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. Fixed TPU bumper pads decelerate the stroke ends.
